Just signed up to brilliant, and forgot to watch the video. Sunk the last hour and a half into it. Very addictive...I mean "fun"...Very fun. Now I gotta go do other stuff and come back to this later.
simon, i really like your narration lately, you're more animated and friendly than when you first started years ago. it's better like this because you're more relaxed 👍
Lost my right hand in 1993. The mirror box is all that saved me from insanity. It felt clenched exactly as Simon described, when I saw what looked like my right hand open up the pain went away pretty much instantly.
I do this kinda work as a medical massage therapist and I treat the attachments to amputated limbs the same way I would as if they were still there. It's pretty amazing when you are just rubbing the air where a knee use to be and the persons ghost knee somehow relaxes
My grandmother, whom hadn’t spoken French since she was a child, spoke fluent French despite her English being severely affected by her strokes. After a couple days the hospital had to find a French-speaking nurse. She was also an accountant for most of her life and, like the French, could count perfectly after. To this day she still has partial-aphasia when it comes to any English speaking
It's weird but not that unusual. Studies show that the brain area supporting the first learned language is smaller than the areas for later learned languages. Hence, strokes tend to interfere with later learned languages more so than the native language even if the language hasn't been used for many years.
@@SkipperMacky it’s not that they learnt a new language, it’s that their most used one (english) became unavailable, so the brain focused on the latent memories of French that she already had from her childhood but hadn’t used for many years.
I have very nearly a quarter of my brain removed due to a very large and nasty cancerous brain tumour. It was the front right portion but I have lost no function. My memory is still as good. And I am quite a clever chap by the way if I do say so myself.
I had a head injury in 1991 and lost most of my right frontal and right temporal lobes. Was a mess with many of the symptoms mentioned in the vid plus epileptic for years, but now it's like it never happened. `except for sleep problems`. Pleased you're alright now. We`re the same best wishes from Graham Coventry UK🤗

All I can say is that I seem to have encountered many people in my life who exhibit signs of only using 10% of their brain. Usually right after lunch, when they "forgot" their wallet...
I was born with hydrocephalus and I’ve had 7 brain surgeries and I’m thinking about going to medical school to become a neurosurgeon or neurologist and the human brain is in my opinion one of the most fascinating things
Same, had a lot of surgeries too, not fun, got 4 Masters degrees. Go for every dream you have, people like you can truly help the world. My hydro buggered my coordination, so surgery isn't for me...or for patients.
@@-Neo_Genesis- shunt insertions and shunt revisions and not they couldn’t help with that. A shunt is like a catheter that drains the excess fluid from the brain to another part of the body to get absorbed
My mom recently passed from MS. She was having a lot of seizures at the end, it would cause things like ..the entire concept of left not existing for her? Or cortical blindness which means she was blind but 100% thought she could see just fine. It was sad but also fascinating because of how complicated the brain is. During these episodes she honestly didn't think anything was wrong, even if the entire left side of her body was paralyzed. It just didn't exist anymore (neither did anything to the left) and she was fine cause it had always been like that
@@BlanBonco not really. An example I remember was the doctor asked what color shirt I was wearing and she immediately and confidently said the wrong color

Recap by Tammy AI
Age 52, I suffered a fall - face versus the lawn and the lawn won. I was in the middle of getting a masters in econ. I couldn't look at a computer for 3 months. It's 3 years later and I still deal with fatigue, intolerance to heat & temp changes, and I have not regained my ability to do higher math (complex algebraic simplification, calculus, linear algebra). I was able to reteach myself math through quadratic equations, and that was it. I got into a knock-down fight with the 1st neurologist because she told me a concussion "wasn't a brain injury". Two things on my side - I research like crazy, and I grasp complex information. Argued that diffuse axonal shear is a brain injury, and what she was siting (nothing on imaging) was the medical textbook definition of the difference between mild/moderate and major TBIs. Ugh. Had to quit the masters program, then had to quit my accounting job as more problems came up. But "not a brain injury", am I right?
I'm an anaesthetic nurse and it's fascinating to know that we're still not sure how anaesthetics work on the brain. We just know that they do work.....
well, you can be yourself without every other body part, except the head. This means we all are just naturally skilled meat-and-bone mech pilots. Fascinating, isn't it?
A friend of mine got hit on the head by a heavy falling object a couple years ago. He immediately was unable to speak. He apparently received some damage to his speech center. Along with that he had some seizures. He was not able to drive for a while because of it. He started getting speech therapy right away and has regained normal speech and the ability to sing again. (He's a musician). There are still some residual effects and he needs to take medication to prevent seizures.
It would make sense that the guy born without a corpus callosum would develop speech centers on both halves of the brain. Neuro plasticity plus the fact that the hemispheres were never connected so there would be a demand for speech recognition on both sides
Why does the brain have to be so complex? My step dad is suffering from dementia and is slowly losing his memory. You can tell him something, and (about) 5 minutes later, he's forgotten what you said. His long term seems to be intact - he remembers his daughter (from previous marriage). I just don't know how long it will be, before me and my mom are complete strangers to him. 😢 Until then, we are both spending as much time as we can with him. After that, 💔 we will do what we can, when we get to that point 😭.
I have minor nerve damage on the right side of my body, due to an accident. I have a loss of sensation, but it appears due to my brain's body map, that I still know I have a right side, although since the incident, I have suffered a loss of sensation which means if I don't see some event which causes me to suffer a minor injury like a cut...I don't know about it until I see it later....annoying. But at least I know it's only peripheral nerve damage and added to that when it first happened I was also very unstable on my feet, but because I learned dance and movement at primary school, those skills have kicked in from my memory and I am not so bad now, plus the muscle spasms I used to get badly are not so bad now, because I believe my motor center of my brain, has found a way around them. I believe this proves that such things can be overcome by your brain, provided they are not too bad to start with.
Man this is a good episode. I learned why people that lose a basic sense, why the others get better. Confirmed something I thought was BS in an episode of House, MD. And I think I know what is wrong with Amos Burton from The Expanse.
I was in the Air Force with a guy who got hit in the head as a kid and now only sees black and white, he always compared it to “an old I Love Lucy episode, not a splash of color.”
Whoa, *that's* interesting! Most colour blindness is caused by the eye not having developed one or more of it's types of 'cones' (humans have three types of cones that pick up on three wavelengths of light, each wavelength being a colour and all colours being a mix of these three). Never heard of someone being colour-blind due to a head injury, I'll have to look up why!😯 EDIT: Okay, looked it up! From what I can gather there a few reason why this happens, two of which are: a) The part of the brain that processes the exact wavelength of the visual input is damaged (so it can't tell the colour), or b) the brain can still tell the colour, but the part of the brain that allows a person to *consciously* know what that colour is is damaged (so the brain can figure out the colours, but the pathway from that part of the brain to the part that let's you consciously pick the colour is damaged, like a PC running properly without a display).
I was totally intrigued with the entire video. I am a brain tumour and meningitis Survivor. Lost Vision in one eye, and i struggle with depth perception issues. I'm just thankful I'm still here, and more than ever, always looking to learn more everyday! Thank you for the great video!
My grandfather had Phantom Limb after a series of right arm amputations due to cancer and he'd feel reflexive actions such as putting out his nonexistent hand to shake when meeting someone.
Excellent video. Something I am fascinated in as a neurodivergent with a bunch of neurological issues, is how the brain functions. I'd love some more in-depth on some of these topics, specially phantom limb, and brain damage. Anything on pain, and neurology would be great too.
I found this especially interesting, having suffered a stroke myself and feeling the effects on my memory, speech and motor control, it took quite a few years have my brain start to get some of that back
This videos was really awesome! Can you do some more videos on the human mind? Or, would you do a video of the amazing capabilities of non-human minds?
17:46 Ok, so now I'm fascinated: I lost my sight so young that I have no memory, conscious or otherwise, of sight. I know because I don't even see in my dreams even though I did live 18 months with perfect vision. So I've always been terrified of the idea of my sight being restored because I believe my brain would not know what to do with the stimuli because it's forgotten how to handle it. But now I wonder how accurate that belief is and also what would happen to my tactile knowledge?
It might take a while, but your brain would likely adjust. It depends I guess on why you lost your vision. If the visual cortex of your brain is undamaged (or could be restored to what it was pre vision loss), I image your vision would return as this is what that part of your brain evolved to do and vision is an incredible asset to have (over any other function that part of your brain might have adjusted to). Given that you did have vision at some point it's possible that your brain would be able to adapt faster than someone who was born blind. It's like how deaf people who get cochlear implants might struggle to make sense of the noise input at first (especially if they were born deaf), but once their brains get a chance to adapt to it the start to make sense.
You might wind up with blindsight. You might wind up able to see, but not know what you're seeing, no conscious awareness of it. It's a fascinating topic.
Thanks for another interesting video. I was lucky enough to get a research fellowship in a lab working with split-brained clients, and the work changed my professional path permanently, as it was so fascinating. One comment on the language centers, you mentioned that it is rare to see them in both hemispheres, but about 30% of ambidextrous people have them.
I think the reason why opposite side control is so you can present the non critical controls to a threat and still fight even if the brain on that side is damaged.
IIRC, the answer is found in the "fish" stage of evolution and is a result of the brain effectively turning upside down in relation to the rest of the body. So in some sense the right half does control the right side and vice versa, but the signal is twisted 180 degrees somewhere along the way and the right half is on the left now. It's around this time that we likely got our laryngeal nerve detour from brain->loop-around-heart->larynx because at that time for those animals that's what they had that worked out best and things only got complicated later on when their descendants inherited the results and had to work off of less-than-ideal plans.
simon, i really like your narration lately, you're more animated and friendly than when you first started years ago. it's better like this because you're more relaxed 👍
Have you done a vedio on the 'Hard Problem of consciences'? (How millions of distinct cell's somehow create an illusion of a single individual). I'm sure it would be captivating.
I'm going for brain surgery in September and of course, being a need, have read so many books in a sort of prep for it. I highly recommend "the brain that changes itself"
I suffered a TIA (mini stroke) a few years ago. I was also diagnosed with bipolar disorder when I was about 12-13. After I had the TIA, I noticed a drastic improvement in how well I was able to register the symptoms of my bipolar disorder (in particular, the duration of which I experienced extreme anger or anxiety). While some of this can be explained with experience and age, the change was too great to be attributed to those factors alone. I also noticed that I have a harder time with containing "happy crying" but I can quickly revert to normal.
I was probably 12 or 13. One of my pet cats lost one of his front legs after being hit by a car. I remember teasing him and being met with a retaliatory swipe at my eye from his stump. It's possible he would have caused real damage if the limb was still there, which I'm sure he intended, and I probably fully deserved! Thank goodness in that instance for phantom limb syndrome!
I learned to control switching sides of my brain. When I'm on my right side, I am and creative, and things starting chaotic. When I switch to my left side, I feel calm and quiet.
"learn and adapt at a rapid pace" also humanity,"lets do the same shit we've been trying for the last 1000 years and see if we get the same result" sure Simon.Sure.
Fascinating indeed! Interesting to learn the mirror box treatment - the TV show "House" actually used this in an episode, and I wondered at the time if that was a real thing or if the character House was (again) being god-tier brilliant. I did know the show tried to base MOST of its medical plot points on real science, so it's nice to see that confirmed. You could probably do a whole video solely on speech center troubles, or cases of brain injury that SHOULD have killed the person and didn't. Though I think y'all already covered Phineas Gage in a Biographics.
If you want know more about mirror box therapy, check out "The Tell-Tale Brain" by V. S. Ramachandran. He pioneered mirror box therapy and made many new insights into how our brains work, or don't work.
It's not true that children learn language faster. It takes about 8 years for a child to learn enough to get around. Meanwhile, a native English speaker, I learned Japanese in 5 years. I can practice a couple hours a day, but children have to practice almost every waking moment
I'm sorry but this isn't exactly correct either. Children can learn hundreds of words and grammar concepts daily without effort, whereas it requires focus and attention once we pass the critical language period. Yes, our abilities and wit allow us to learn languages faster later in life (I speak Russian and am currently studying Spanish), but we can no longer learn them simply by being absorbed in them, we must actively study and practice.
@@andyyang3029 you can totally learn them like a kid if you have total immersion like a kid would. The biggest difference is how we experience the language. I learned tons of Japanese passively from watching anime without subtitles. It's probably why I was the best in my classes. I'm currently learning Polish, and I've been watching lots of videos that don't have English, just Polish, and I've learned so much. I had trouble learning English as a kid btw
@@kokitsunetora As a native English speaker, I can confidently say that English is a nonsensical language, and any rules we try to apply to it is in vain. With it's multitude of origins, it's a bastard language through-and-through. At least with Japanese the 'vowels' all make the same sounds rather than have several different ones for each one 😂
@@hedera1332 Japanese was so much easier to learn, minus the kanji and keigo 😂. Polish is actually harder than English in my opinion. The words and grammar aren't that hard, but the cases trip up native speakers. And even Poles have asked why foreigners want to learn their language 😂
When my grandmother had a stroke when she was 91 years old. I went to see her in the hospital she was speaking Swedish because she was born and raised iean Sweden. It took me asking her to speak English a couple of times before she started talking in English. The nurse came into the room and said that my grandmother was speaking gibberish, and I told the nurse that she was wrong she was speaking Swedish.
As a tall person I can attest that living with head trauma is challenging in haunting ways. Sure sometimes you remember the color and texture of a childhood blanket lost decades ago, then you forget the name of your coworkers.
A long time ago I remember hearing that the "We only use 10% of our brain" claim to have been based on an observation that only 10% of our neurons were firing at a given time. The retort was that it wouldn't have been a good thing for all of them to be simultaneously firing. I have no idea if it was true, but it sounded good.
Optic ataxia can occur because what your eye perceives goes to different parts of your brain: One area that identifies *what* an object is and one that identifies *where* it is. Optic ataxia occurs when there is something wrong with the 'where it is' part (either at that part of the brain or somewhere else along the pathway from the eyes to that area). This means that people with damage to this area/pathway are able to identify an object, but they can't properly discern where it is so have difficulty coordinating their body to interact with objects. The opposite is also possible, where a patient can't identify *what* an object is, but is able to tell *where* it is (I'm not sure what the term for this condition is). This one I think is weirder as a lot of people with this are able to still interact with objects without being able to tell what it is (the example that was in my text book was using a lock, a person may not be able to identify it as a lock, but their hand will still get the feeling to try and do the twisting motion that is required to use the lock. They can still 'see' it, they just don't know what it is). Another interesting thing I learned was about 'proprioception', this is a sense we have that allows use to know where our limbs are without needing to look at them (eg, if I shut my eyes I can know where my arm is if I were to raise it above my head, or if I were to open and close my hand, etc). We looked at the case study of a man who was injured and lost the ability to feel where all of his limbs were. Doctors thought he would be bed ridden and essentially unable to move for the rest of his life, but with months of effort he taught himself to move and walk again by looking at his limbs and imagining moving them. This means to walk and do activities he has to actively think about them rather than doing them subconsciously, but it's still amazing that he was able to regain any movement at all. As for the brain re-purposing areas; many people who are blind or become blind are able to do a form of echolocation (some to an insane level, look up Ben Underwood, who has unfortunately passed away but had an amazing use of echolocation). The part of their brain that is usually used for vision is generally re-purposed to allow for this. The brain is truly amazing!!
🤯this is why I watched Simon Whistler no matter what channel it is I've been trying to get my wife to watch him because I watch five or six of his videos a day and it's just like wow what a learning experience and she went to school in Rexburg Idaho and I feel she can greatly benefit from watching videos like this since her IQ I guess is about 87 which makes it hard to communicate and teacher stuff when my IQ is 145 Simon you are a godsend and please don't ever stop making videos
I just watched a really interesting video explaining neuroplasticity and how it is re-activated for a short period of time after a trauma to the brain like stroke for example. If you start teaching the people who have suffered a stroke really quickly after it happened - you can reverse a lot more of the damage than starting the learning process just a week later. And - if that's not crazy enough - they did an experiment with mice. If the mouse had a stroke and was immediately taught how to be a mouse again - great success. If the learning was allowed later - the results were much worse. But that's not the weird part! If the mouse who missed the re-activation period of the first stroke and was as a result brain damaged, was given a second stroke later and then immediately started to learn again - even the damage from the first stroke was able to be reversed! The re-activated neuroplasticity power allowed the brain just repair everything it found to be faulty, doesn't matter if the trauma happened in the past! Truly fascinating!

Stroke Patient here, Right Brain-- Young age 31 years old, complete Left Side Weakness-- can't feel anything left side... I also have left side neglect-- I ignore objects on my left side. I often hit walls and just THINGS on the left side that I didn't see ( or even feel until it knocks me over). It's bizarre. I do all sorts of things to try and bring back my awareness of my left but it's not easy. I do the mirror therapy often. Seems to help!

"The human brain is the only object in the known universe that can predict its own future and tell its own fortune. The fact that we can make disastrous decisions even as we forsee their consequences is the great, unsolved mystery of human behavior.

The mirror box only works on about 50% of patients and at best relieves about 40% of a patient's pain. Not bad, for a noninvasive treatment. But not great if you're not in the 50%.
Simon you should do a video on the emerging science of the connection between autoimmunity-clinical infection - inflammation and mental health disorders, this area challenges the psychology vs physician dogma. Examples Encephalitis, PANS & PANDAS, oh and the film Awakenings.
The corpus callosotomy is only used in extreme cases where patients are literally seizing to the point of brain damage, many times in a day. There's a great interview on SBSK with a young woman who had the procedure when she was really small. Her mother describes her condition before the surgery, she was barely able to function at all, and her mental development was severely stunted as a result. I can see that you're able to watch a video on a fairly complex topic and make a completely coherent comment. I'm confident that no doctor would ever decide that the benefits would outweigh the risks in your case. I hope this makes you feel better. I realize it was just an offhand remark, but I know what medical anxiety can be like sometimes 🙃
@@ForestFire369 okay this genuinely made me feel better thank you so much. I seize multiple times a week and I do have slight brain damage as a result, and my neurologist basically told me 'idk what else to do' so it's always eating away at me
Thank you for this amazing information about the brain. It is interesting and I was unaware of the many facts mentioned. I believe that there is much more to be learned about the brain and the rest of the body. All of the functions of the brain are fascinating.
"Our incredible memory is what makes humans truly unique." Except, yano, for elephants. And other creatures that we simply haven't figured out a way to test. Humans may well be the only animal who cares so deeply about being the only animal who does something. That said, the brain is a tremendously amazing apparatus, and this was a great video.

It sounds a little weird, when you say, that the brain sends epileptic signals. Epilepsy is by definition the brain sending wrong signals. Epileptic seizures can also be very different, depending on how much and which part of the brain is affected. In myoclonic seizures only parts of the brain is affected, which is why some of us can walk and talk (it rarely makes sense). Tonic-clonic seizures are the ones, where you're on the floor shaking. It must be those, you are talking about here (also called grand-mal, but the term is outdated). Many of us have problems finding words, so it's a sideeffect some people may not even notice. EXTRA INFO!: If you are present when someone is having a tonic-clonic seizure, then put something soft under their head and then don't touch them. Don't put something in their mouth, and don't try to stop them from shaking. If you're scared, call for an ambulance, so professionals can take over, but otherwise just call if the seizure lasts for more then five minutes. With myoclonic seizures just drag them to somewhere, where they can sit. Every two minutes ask an obvious question with no yes/no answer. When they can answer, they are slowly waking up again. It takes time to wake up, and they shouldn't be alone afterwards. Needing to sleep afterwards is normal and completely okay
All truly intelligent life is going to have a brain as complex as ours. If and when we meet other intelligent life, it will be fascinating to swop anatomical data on each other. That of course is providing both parties, are honest, friendly and willing. It is all 🤯🤓😎😁

It would be fascinating to see a video about aphantasia (people who can't see anything in their mind's eye) and hyperfantasia (the opposite, where people can see perfect photographs and movies play in their mind). It's really interesting, especially as an artist & creative person who has aphantasia & who has friends who have hyperfantasia or something somewhere between the two, yet aren't creative. It's wild
I enjoyed this so much! I'm a huge Alice Sheldon & Harlan Ellison fan. My Mom got me into Ellison, and I got her into Alice Sheldon! Audible has a good selection of Ellison's collections recently, I think I have 13 of his books (short stories galore!) available to listen to, and I do very often. That number includes his general fiction & the things he wrote about being in a gang too.
We now know the brain uses a sort of wireless communication between areas that doesn't seem to be limited by direct neuron connections, too. A lack of the fatty insulation facilitates this, where we used to think the insulation was required for optimum signaling. The more we learn, the more we realize we know approximately jack. Also, glad you mentioned the concept of a functional brain map being vague. Because again, the more we learn...
you know how we cant read in our dreams because the language center is in only half of our brain? I wonder if Kim Peek can since he has language centers in both halves.

You forgot alien hand syndrome. Based on that, I actually have a theory that your conscious and your subconscious reside on opposite hemispheres and can think independently of one another. I would imagine that alien hand syndrome could probably also be treated by speaking out loud to your other hemisphere, as it can't hear your thoughts.
When I have serotonin levels drop due to missing a regular dose of an SSRI, I'll typically have altered proprioception in addition to the other symptoms such as brain zaps that cause consciousness to briefly fade. If I turn my head, my view changes as normal but I still feel my head pointing straight ahead. After a roughly a second I'll feel my head turn. I don't currently know if this is a direct result of reduced serotonin or if it's somewhere down the metabolic chain and directly controlled by something serotonin affects.
I know what you mean. I was on an ssri for about 18 months, then came off them cold turkey. I'd been told that they weren't in any way addictive, so I just stopped taking them. The brain zaps you mention were extremely disconcerting to say the least. It literally felt like I was being subjected to an electric shock. I did not like it at all.
A friend in school once asked me if i thought our soul was controling our body like a sim game, but our animal consciousness is still alive and trapped inside
Four actually. Your left and right brains are separate entities, both thinking in their own ways, one emotionally, one 'logically', one able to speak and see and do, the other blind and mute, both slaves to each other, as well as your primal brain, and your heart - largely unheard by most of humanity.

To this day she still has partial-aphasia when it comes to any English speaking
Being able to instantly speak another language is soooo weird! You'd think that it was something you'd have to learn. Amazing.
It's weird but not that unusual. Studies show that the brain area supporting the first learned language is smaller than the areas for later learned languages. Hence, strokes tend to interfere with later learned languages more so than the native language even if the language hasn't been used for many years.
@@peterjhayashi do you think people can have a sudden capacity for advanced mathematics and equation solving in the same way?
@@SkipperMacky it’s not that they learnt a new language, it’s that their most used one (english) became unavailable, so the brain focused on the latent memories of French that she already had from her childhood but hadn’t used for many years.

I have very nearly a quarter of my brain removed due to a very large and nasty cancerous brain tumour. It was the front right portion but I have lost no function. My memory is still as good. And I am quite a clever chap by the way if I do say so myself.
I had a head injury in 1991 and lost most of my right frontal and right temporal lobes. Was a mess with many of the symptoms mentioned in the vid plus epileptic for years, but now it's like it never happened. `except for sleep problems`. Pleased you're alright now.

Or cortical blindness which means she was blind but 100% thought she could see just fine. It was sad but also fascinating because of how complicated the brain is. During these episodes she honestly didn't think anything was wrong, even if the entire left side of her body was paralyzed. It just didn't exist anymore (neither did anything to the left) and she was fine cause it had always been like that

Recap by Tammy AI
Age 52, I suffered a fall - face versus the lawn and the lawn won. I was in the middle of getting a masters in econ. I couldn't look at a computer for 3 months. It's 3 years later and I still deal with fatigue, intolerance to heat & temp changes, and I have not regained my ability to do higher math (complex algebraic simplification, calculus, linear algebra). I was able to reteach myself math through quadratic equations, and that was it.
I got into a knock-down fight with the 1st neurologist because she told me a concussion "wasn't a brain injury". Two things on my side - I research like crazy, and I grasp complex information. Argued that diffuse axonal shear is a brain injury, and what she was siting (nothing on imaging) was the medical textbook definition of the difference between mild/moderate and major TBIs. Ugh. Had to quit the masters program, then had to quit my accounting job as more problems came up. But "not a brain injury", am I right?
Really sorry to hear that. Strange Parts on TH-cam recently had success treating his TBI from a blow to the head. Video about a month ago
I'm an anaesthetic nurse and it's fascinating to know that we're still not sure how anaesthetics work on the brain. We just know that they do work.....

A friend of mine got hit on the head by a heavy falling object a couple years ago. He immediately was unable to speak. He apparently received some damage to his speech center. Along with that he had some seizures. He was not able to drive for a while because of it. He started getting speech therapy right away and has regained normal speech and the ability to sing again. (He's a musician).
There are still some residual effects and he needs to take medication to prevent seizures.
It would make sense that the guy born without a corpus callosum would develop speech centers on both halves of the brain. Neuro plasticity plus the fact that the hemispheres were never connected so there would be a demand for speech recognition on both sides
I’d go absolutely insane if my vision started lagging like a bad COD lobby.

Why does the brain have to be so complex?
My step dad is suffering from dementia and is slowly losing his memory. You can tell him something, and (about) 5 minutes later, he's forgotten what you said. His long term seems to be intact - he remembers his daughter (from previous marriage).

You don't know that for sure.
I have minor nerve damage on the right side of my body, due to an accident. I have a loss of sensation, but it appears due to my brain's body map, that I still know I have a right side, although since the incident, I have suffered a loss of sensation which means if I don't see some event which causes me to suffer a minor injury like a cut...I don't know about it until I see it later....annoying.
But at least I know it's only peripheral nerve damage and added to that when it first happened I was also very unstable on my feet, but because I learned dance and movement at primary school, those skills have kicked in from my memory and I am not so bad now, plus the muscle spasms I used to get badly are not so bad now, because I believe my motor center of my brain, has found a way around them.
I believe this proves that such things can be overcome by your brain, provided they are not too bad to start with.
Man this is a good episode. I learned why people that lose a basic sense, why the others get better. Confirmed something I thought was BS in an episode of House, MD. And I think I know what is wrong with Amos Burton from The Expanse.

I was in the Air Force with a guy who got hit in the head as a kid and now only sees black and white, he always compared it to “an old I Love Lucy episode, not a splash of color.”
Whoa, *that's* interesting! Most colour blindness is caused by the eye not having developed one or more of it's types of 'cones' (humans have three types of cones that pick up on three wavelengths of light, each wavelength being a colour and all colours being a mix of these three). Never heard of someone being colour-blind due to a head injury, I'll have to look up why!😯
EDIT: Okay, looked it up! From what I can gather there a few reason why this happens, two of which are:
a) The part of the brain that processes the exact wavelength of the visual input is damaged (so it can't tell the colour), or
b) the brain can still tell the colour, but the part of the brain that allows a person to *consciously* know what that colour is is damaged (so the brain can figure out the colours, but the pathway from that part of the brain to the part that let's you consciously pick the colour is damaged, like a PC running properly without a display).

This videos was really awesome! Can you do some more videos on the human mind? Or, would you do a video of the amazing capabilities of non-human minds?
17:46 Ok, so now I'm fascinated: I lost my sight so young that I have no memory, conscious or otherwise, of sight. I know because I don't even see in my dreams even though I did live 18 months with perfect vision. So I've always been terrified of the idea of my sight being restored because I believe my brain would not know what to do with the stimuli because it's forgotten how to handle it. But now I wonder how accurate that belief is and also what would happen to my tactile knowledge?
It might take a while, but your brain would likely adjust. It depends I guess on why you lost your vision. If the visual cortex of your brain is undamaged (or could be restored to what it was pre vision loss), I image your vision would return as this is what that part of your brain evolved to do and vision is an incredible asset to have (over any other function that part of your brain might have adjusted to). Given that you did have vision at some point it's possible that your brain would be able to adapt faster than someone who was born blind.
It's like how deaf people who get cochlear implants might struggle to make sense of the noise input at first (especially if they were born deaf), but once their brains get a chance to adapt to it the start to make sense.
You might wind up with blindsight. You might wind up able to see, but not know what you're seeing, no conscious awareness of it. It's a fascinating topic.
Thanks for another interesting video. I was lucky enough to get a research fellowship in a lab working with split-brained clients, and the work changed my professional path permanently, as it was so fascinating. One comment on the language centers, you mentioned that it is rare to see them in both hemispheres, but about 30% of ambidextrous people have them.
I think the reason why opposite side control is so you can present the non critical controls to a threat and still fight even if the brain on that side is damaged.
Interesting theory. Where did you hear this? Just curious
IIRC, the answer is found in the "fish" stage of evolution and is a result of the brain effectively turning upside down in relation to the rest of the body. So in some sense the right half does control the right side and vice versa, but the signal is twisted 180 degrees somewhere along the way and the right half is on the left now. It's around this time that we likely got our laryngeal nerve detour from brain->loop-around-heart->larynx because at that time for those animals that's what they had that worked out best and things only got complicated later on when their descendants inherited the results and had to work off of less-than-ideal plans.

Have you done a vedio on the 'Hard Problem of consciences'? (How millions of distinct cell's somehow create an illusion of a single individual). I'm sure it would be captivating.
I'm going for brain surgery in September and of course, being a need, have read so many books in a sort of prep for it. I highly recommend "the brain that changes itself"
As somebody with a brain injury caused by a brain tumour, I find this very interesting! Thank you for sharing!
I suffered a TIA (mini stroke) a few years ago. I was also diagnosed with bipolar disorder when I was about 12-13.
After I had the TIA, I noticed a drastic improvement in how well I was able to register the symptoms of my bipolar disorder (in particular, the duration of which I experienced extreme anger or anxiety). While some of this can be explained with experience and age, the change was too great to be attributed to those factors alone.
I also noticed that I have a harder time with containing "happy crying" but I can quickly revert to normal.
I was probably 12 or 13. One of my pet cats lost one of his front legs after being hit by a car. I remember teasing him and being met with a retaliatory swipe at my eye from his stump. It's possible he would have caused real damage if the limb was still there, which I'm sure he intended, and I probably fully deserved! Thank goodness in that instance for phantom limb syndrome!
The fact we can conceive infinity in our finite minds is pretty amazing.
Good episode, Simon... Nicely done.
Ya, my brain hates itself I've decided.
I learned to control switching sides of my brain. When I'm on my right side, I am and creative, and things starting chaotic. When I switch to my left side, I feel calm and quiet.
"learn and adapt at a rapid pace" also humanity,"lets do the same shit we've been trying for the last 1000 years and see if we get the same result" sure Simon.Sure.
We routinely do both of these things. It is no surprise, definitely not impossible.
Fascinating indeed! Interesting to learn the mirror box treatment - the TV show "House" actually used this in an episode, and I wondered at the time if that was a real thing or if the character House was (again) being god-tier brilliant. I did know the show tried to base MOST of its medical plot points on real science, so it's nice to see that confirmed.
You could probably do a whole video solely on speech center troubles, or cases of brain injury that SHOULD have killed the person and didn't. Though I think y'all already covered Phineas Gage in a Biographics.
If you want know more about mirror box therapy, check out "The Tell-Tale Brain" by V. S. Ramachandran. He pioneered mirror box therapy and made many new insights into how our brains work, or don't work.
This is the most fascinating video I've seen in a while out of all Simon's channels
Great video. Always been fascinated by the jelly in our head
Odd that they learned braille blindfolded, but then forget it when the blindfold is off.
Because the part of the brain allowing them to learn it more quickly returned to its original function ;)
It's like having storage on a device. Vision is a large app, so they had to remove the braille to make room for it again lmao.
Simon gets so gesticulatory in his casual wear on this channel. I am a fan.

It's not true that children learn language faster. It takes about 8 years for a child to learn enough to get around. Meanwhile, a native English speaker, I learned Japanese in 5 years. I can practice a couple hours a day, but children have to practice almost every waking moment
I'm sorry but this isn't exactly correct either. Children can learn hundreds of words and grammar concepts daily without effort, whereas it requires focus and attention once we pass the critical language period. Yes, our abilities and wit allow us to learn languages faster later in life (I speak Russian and am currently studying Spanish), but we can no longer learn them simply by being absorbed in them, we must actively study and practice.
@@andyyang3029 you can totally learn them like a kid if you have total immersion like a kid would. The biggest difference is how we experience the language. I learned tons of Japanese passively from watching anime without subtitles. It's probably why I was the best in my classes. I'm currently learning Polish, and I've been watching lots of videos that don't have English, just Polish, and I've learned so much. I had trouble learning English as a kid btw
@@kokitsunetora As a native English speaker, I can confidently say that English is a nonsensical language, and any rules we try to apply to it is in vain. With it's multitude of origins, it's a bastard language through-and-through. At least with Japanese the 'vowels' all make the same sounds rather than have several different ones for each one 😂
@@hedera1332 Japanese was so much easier to learn, minus the kanji and keigo 😂. Polish is actually harder than English in my opinion. The words and grammar aren't that hard, but the cases trip up native speakers. And even Poles have asked why foreigners want to learn their language 😂
When my grandmother had a stroke when she was 91 years old. I went to see her in the hospital she was speaking Swedish because she was born and raised iean Sweden. It took me asking her to speak English a couple of times before she started talking in English. The nurse came into the room and said that my grandmother was speaking gibberish, and I told the nurse that she was wrong she was speaking Swedish.
As a tall person I can attest that living with head trauma is challenging in haunting ways.
Sure sometimes you remember the color and texture of a childhood blanket lost decades ago, then you forget the name of your coworkers.
A long time ago I remember hearing that the "We only use 10% of our brain" claim to have been based on an observation that only 10% of our neurons were firing at a given time. The retort was that it wouldn't have been a good thing for all of them to be simultaneously firing.
I have no idea if it was true, but it sounded good.
Optic ataxia can occur because what your eye perceives goes to different parts of your brain: One area that identifies *what* an object is and one that identifies *where* it is. Optic ataxia occurs when there is something wrong with the 'where it is' part (either at that part of the brain or somewhere else along the pathway from the eyes to that area). This means that people with damage to this area/pathway are able to identify an object, but they can't properly discern where it is so have difficulty coordinating their body to interact with objects.
The opposite is also possible, where a patient can't identify *what* an object is, but is able to tell *where* it is (I'm not sure what the term for this condition is). This one I think is weirder as a lot of people with this are able to still interact with objects without being able to tell what it is (the example that was in my text book was using a lock, a person may not be able to identify it as a lock, but their hand will still get the feeling to try and do the twisting motion that is required to use the lock. They can still 'see' it, they just don't know what it is).
Another interesting thing I learned was about 'proprioception', this is a sense we have that allows use to know where our limbs are without needing to look at them (eg, if I shut my eyes I can know where my arm is if I were to raise it above my head, or if I were to open and close my hand, etc). We looked at the case study of a man who was injured and lost the ability to feel where all of his limbs were. Doctors thought he would be bed ridden and essentially unable to move for the rest of his life, but with months of effort he taught himself to move and walk again by looking at his limbs and imagining moving them. This means to walk and do activities he has to actively think about them rather than doing them subconsciously, but it's still amazing that he was able to regain any movement at all.
As for the brain re-purposing areas; many people who are blind or become blind are able to do a form of echolocation (some to an insane level, look up Ben Underwood, who has unfortunately passed away but had an amazing use of echolocation). The part of their brain that is usually used for vision is generally re-purposed to allow for this.
The brain is truly amazing!!
🤯this is why I watched Simon Whistler no matter what channel it is I've been trying to get my wife to watch him because I watch five or six of his videos a day and it's just like wow what a learning experience and she went to school in Rexburg Idaho and I feel she can greatly benefit from watching videos like this since her IQ I guess is about 87 which makes it hard to communicate and teacher stuff when my IQ is 145 Simon you are a godsend and please don't ever stop making videos

So when I close my eyes to focus on listening to something more intently, that might actually be doing something??? Fascinating!
"10 times this unbelievable estimate" is ridiculous, the actual size of a brain is roughly 10^20 bytes
I just watched a really interesting video explaining neuroplasticity and how it is re-activated for a short period of time after a trauma to the brain like stroke for example. If you start teaching the people who have suffered a stroke really quickly after it happened - you can reverse a lot more of the damage than starting the learning process just a week later. And - if that's not crazy enough - they did an experiment with mice. If the mouse had a stroke and was immediately taught how to be a mouse again - great success. If the learning was allowed later - the results were much worse. But that's not the weird part! If the mouse who missed the re-activation period of the first stroke and was as a result brain damaged, was given a second stroke later and then immediately started to learn again - even the damage from the first stroke was able to be reversed! The re-activated neuroplasticity power allowed the brain just repair everything it found to be faulty, doesn't matter if the trauma happened in the past! Truly fascinating!

The corpus callosotomy is only used in extreme cases where patients are literally seizing to the point of brain damage, many times in a day. There's a great interview on SBSK with a young woman who had the procedure when she was really small. Her mother describes her condition before the surgery, she was barely able to function at all, and her mental development was severely stunted as a result.
I can see that you're able to watch a video on a fairly complex topic and make a completely coherent comment. I'm confident that no doctor would ever decide that the benefits would outweigh the risks in your case. I hope this makes you feel better. I realize it was just an offhand remark, but I know what medical anxiety can be like sometimes 🙃
@@ForestFire369 okay this genuinely made me feel better thank you so much. I seize multiple times a week and I do have slight brain damage as a result, and my neurologist basically told me 'idk what else to do' so it's always eating away at me

It sounds a little weird, when you say, that the brain sends epileptic signals. Epilepsy is by definition the brain sending wrong signals.
Epileptic seizures can also be very different, depending on how much and which part of the brain is affected. In myoclonic seizures only parts of the brain is affected, which is why some of us can walk and talk (it rarely makes sense). Tonic-clonic seizures are the ones, where you're on the floor shaking. It must be those, you are talking about here (also called grand-mal, but the term is outdated).
Many of us have problems finding words, so it's a sideeffect some people may not even notice.
EXTRA INFO!:
If you are present when someone is having a tonic-clonic seizure, then put something soft under their head and then don't touch them. Don't put something in their mouth, and don't try to stop them from shaking. If you're scared, call for an ambulance, so professionals can take over, but otherwise just call if the seizure lasts for more then five minutes.
With myoclonic seizures just drag them to somewhere, where they can sit. Every two minutes ask an obvious question with no yes/no answer. When they can answer, they are slowly waking up again.
It takes time to wake up, and they shouldn't be alone afterwards. Needing to sleep afterwards is normal and completely okay

I know, I have what I call "The octopus" and "the otter" and I've spent most of my life working them out. Consider my brains to be bodybuilders/powerlifters.
It would be fascinating to see a video about aphantasia (people who can't see anything in their mind's eye) and hyperfantasia (the opposite, where people can see perfect photographs and movies play in their mind). It's really interesting, especially as an artist & creative person who has aphantasia & who has friends who have hyperfantasia or something somewhere between the two, yet aren't creative. It's wild
I enjoyed this so much! I'm a huge Alice Sheldon & Harlan Ellison fan. My Mom got me into Ellison, and I got her into Alice Sheldon!
Audible has a good selection of Ellison's collections recently, I think I have 13 of his books (short stories galore!) available to listen to, and I do very often. That number includes his general fiction & the things he wrote about being in a gang too.
The mirror box is fascinating idea.
We now know the brain uses a sort of wireless communication between areas that doesn't seem to be limited by direct neuron connections, too. A lack of the fatty insulation facilitates this, where we used to think the insulation was required for optimum signaling. The more we learn, the more we realize we know approximately jack.
Also, glad you mentioned the concept of a functional brain map being vague. Because again, the more we learn...
One day it may even be possible to find treatments for severe concussion or severe brain damage in general.
My brain is my favorite side project. :D Great vid
you know how we cant read in our dreams because the language center is in only half of our brain? I wonder if Kim Peek can since he has language centers in both halves.
I didn't know that! Gonna try and read in my dreams now, if I manage to get into a lucid one that has words in it xD
I'm pretty sure I have vividly read small sentences in my dreams. Like notes on fridges or few sentences maybe. I have had bad brain trauma history through life. I will be anxious to observe better and test what your questioning.
@@julybliss4440 I've wondered if I can do the same. It may not be that I'm reading, but that I just know what text should be there because it's all a projection of thoughts. Last night, I 'read' a Wikipedia article but don't recall seeing the words.
Can confirm I can read in dreams. I was in an elevator and I could read an "emergency stop' button.
@@hedera1332 i can see a stop sign and "know" what it says, but since i learned this factoid ive been trying really hard to read in dreams and the letters keep changing and it doesnt make sense
You forgot alien hand syndrome. Based on that, I actually have a theory that your conscious and your subconscious reside on opposite hemispheres and can think independently of one another. I would imagine that alien hand syndrome could probably also be treated by speaking out loud to your other hemisphere, as it can't hear your thoughts.
When I have serotonin levels drop due to missing a regular dose of an SSRI, I'll typically have altered proprioception in addition to the other symptoms such as brain zaps that cause consciousness to briefly fade. If I turn my head, my view changes as normal but I still feel my head pointing straight ahead. After a roughly a second I'll feel my head turn. I don't currently know if this is a direct result of reduced serotonin or if it's somewhere down the metabolic chain and directly controlled by something serotonin affects.
I know what you mean. I was on an ssri for about 18 months, then came off them cold turkey. I'd been told that they weren't in any way addictive, so I just stopped taking them. The brain zaps you mention were extremely disconcerting to say the least. It literally felt like I was being subjected to an electric shock. I did not like it at all.

A friend in school once asked me if i thought our soul was controling our body like a sim game, but our animal consciousness is still alive and trapped inside
Wonderful video. VS Ramachandran is brilliant.
Someone: "If the human brain was simple enough for us to understand, we would be too simple too understand it"
Four actually.
Your left and right brains are separate entities, both thinking in their own ways, one emotionally, one 'logically', one able to speak and see and do, the other blind and mute, both slaves to each other, as well as your primal brain, and your heart - largely unheard by most of humanity.
