Speech is not always on the left side of the brain. My mother died of a brain tumor. She was, also, born left handed, but when she went to school they forced her to be right handed. When she had a FMRI they discovered her speech was on the right side. This is when I learned that she was born left handed, and that, commonly, which side of the brain has speech and handedness form together.
do you think whenever people say stuff like “haha my brain is being so dumb today” we’re actually talking about our mute brain hemisphere with our speaking brain hemisphere?
Same here. I find it difficult to recognise people. I will sometimes recognise that I know someone but not know where from, seeing someone out of the usual context appears to be a problem for me.
Social scientists already know some of the answers to intelligence. It also largely depends on starting conditions, where they grew up, the status of the family, family ideology, their local infrastructure and transit, etc. Like one of the greatest predictor of a poor child being able to obtain a college degree? Living near a rapid transit. For the general child getting a college degree? Living in the right family that has a tradition of intellectual pursuits, or even living in the right zip code in the US (no idea about other countries). The primary cause why many born Deaf people have poor education and poor perceived intelligence? Language deprivation, usually, or improper balance of their education focusing far too much on oralist approach or some other Manual English or other Manualized oral languages causing the rest of their education to suffer, as well having to suffer trauma the entire way through childhood.
So region of the brain responsible for music is closer to the emotion region and that might explain why are we so prone to associating music to emotions?
Keep in mind that "statistical significance" is not a measure of effect size. It is simply a measure of whether a study had enough data to reasonably conclude that the effect was not completely zero (under some assumptions). I noticed your reporters emphasizing the word "significant" as if it means important or large differences were concluded.
@@Speed001 That's not what the word means... The word you should look into is hypothesis. In science, a theory is an already-proven, through experiment, postulate. The hypothesis comes first, the scientist then tests it multiple, repeatable times to be sure that hypothesis is right, **then** builds the theorem around it. The word theory, the way non-scientists use it--to mean an unproven idea--is different from how actual scientists, use it--a proven idea that's still perhaps being built upon. You wouldn't call gravity "just a theory" and mean it's something unproven and then jump off of a building expecting to float, now would you?

It honestly never occurred to me that our brains use more than one kind of cell. But in retrospect, it makes a lot of sense. Most organs in our body are made up of multiple kinds of tissue cells. Our blood is made up of three types of cells (and that’s excluding the different subtypes of white blood cells) that all do different things. So to think the most important and complex organ in the body, doing as much as it does literally all the time, would operate using only one kind of cell is kinda ridiculous, honestly.

"Surgically changing it could be the best way to heal it." Uhh...lying by omission? We're not going to talk about the major complications that can happen from split brain surgery, due to the cross communication of the brain? (Left controls right, right controls left) Or how brain surgery is MASSIVELY different from any other surgery because the brain is the only organ that doesn't regenerate/heal like the rest of your body? Or that ANY type of brain surgery is a roll of the dice? The rest of your body typically behaves in a predictable way during surgery i.e. when you clamp a blood vessel, it re-routes blood flow in a specific way, most specific surgeries have a known outcome etc. Neurosurgeons (even the best in the world) can give you an _idea_ of what _should_ happen, but there's absolutely no guarantee because the brain could refuse to re-route blood flow, healing/compensating for damage is completely random, and there's no way for a neurosurgeon or neurologist to 100% or even 80-90% give you a recovery prognosis until well after the surgery. It _can_ be the best way to heal it, BUT it can also be massively detrimental. I met sooo many people who had brain surgery after having mine, some for different tumours or causes for it along with 3 that had the same tumour and exact same surgery, and every single one of us healed differently. Not a single one of us had the same results. I was VERY lucky, because some of the people I spoke with had various types of paralysis (regardless of if it was complicated or minor surgery) one person with the same rare tumour (smaller than mine) ended up healing to only 70% of her pre-surgery functionality, and the list goes on.
We just need to learn more about it and where out consciousness originates from b4 trying to heal surgically. You are correct and I agree we shouldn't do anything that risk outweigh benefit .. with that Said "at the right times" its necessary to take risk in order to learn and progress
Your brain does regenerate to some degree .. it is different in each case but the brain can make new connections that do not run afoul with mental health .. you may want to look into modern nuero-placistity
@@jasonhiggins6236 But that's not regeneration. If you get a cut the wound scabs over, and creates new cells. Yes, there might be a scar, but it's overall the same. The brain doesn't create new brain cells when you damage them. Once those cells are dead, they're permanently dead. That being said, you can indeed make new neutral pathways to make up for the ones lost, but that's changing how your brain works, to compensate for the lost cells, not actual healing. It's absolutely amazing, and fascinating, just very different from how surgical healing works on the rest of your body.
@@Amarianee from my research new brain cell generation not regeneration of old cell but generating new ones has been shown with something as simple as thc/cbd tinctures.. may want to look into it.. it's a certain cannabinoid that they can isolate ... also , not legal here but I've heard, not seen study or read publishing that stem cell and something from cord blood " helped" regeneration . I commented before reading all your comment. I'm sincerely not trying g to troll or be bothersome.. just bored really and I've been struggling since 2012 with trying to rewire my brain after an incident left me in hospital for a few weeks .. I left "different " and I've been trying to learn why.. my memory pre 2012 is nearly wiped but now I take information in at a crazy rate .. my wife and mom says my speech has changed and I know somethings changed .. ironically in my case I think for the better although.. who knows
What's in my brain? Minor brain damage. Always been straight edge, because I LOVED my brain as a kid/teen and still constantly pursue knowledge...then they found one of the rarest tumors in the world, in 2008 when I was 19. No rhyme or reason, just one of those random situations, and was so slow growing, it had probably started years ago (it was 2 in when it was found). Treated that gray matter so good, and it betrayed me, just my luck 😒
@@arzelzon1137 I'm now epileptic (controlled with meds though, another bit of good luck) and, for a while, my short term memory was severely impacted. That got better over time, but it took a good 3yrs before it was back to "normal." Normal for _me_ was above average. I used to be able to recite movies/quotes verbatim after watching anything, but now it's pretty average. I also get migraines a few times a month, whereas I used to only get them 1-3 times a year. I got off pretty easy compared to others I've met, and especially considering how large the tumor was, right in the center (it was blocking the third ventricle, causing spinal fluid to build up). We didn't have time to do a biopsy because the pressure would have killed me in a week, tops, so the neurosurgeon was basically going in blind. Luckily, it ended up being gelatinous and was able to be suctioned, rather than a hard tumour, which would have required cutting and inevitably more damage. It was also partially cancerous (grade 2 & 3 cells), so I spent about 10yrs getting follow up MRIs, just to make sure it didn't come back. Pineal parenchymal tumor of intermediate differentiation. Spent my 20th birthday in the hospital.
@@arzelzon1137 I'm assuming you meant symptoms post surgery. For anyone worried, the symptoms pre-diagnosis was severe headaches that felt wrong. I've never had a headache like that or since then. It felt like massive pressure built up in my skull...because it is was. The vomiting started as once every few weeks, and progressively got more and more frequent. 3 different urgent care doctors dismissed me and called it, "muscle spasms," "migraines," and, "too much iron in [your] diet." It was an e.r. doctor that pushed for a CT scan because he was concerned he couldn't find anything wrong, despite my symptoms. He literally saved my life. The moral is: you know your body better than anyone else. If you _know_ something is wrong, and the doctors blow you off, put your foot down. You're the patient and whether it's private healthcare or universal, you pay their salary, and it's their job to treat you. Don't let doctors/hospitals push you around, you've got a right to be listened to, and it could save your life.
@@Richard-tj1yh Of course! After coming to terms with everything, I realized that my situation could help others, so I use it as an opportunity to advocate for patients and people with chronic illnesses. The best thing you can remember as a doctor is, listen to your patients. It's ok to not have an answer. It will always be better to tell someone you're "not sure, but you'll keep trying," rather than, "I can't find anything, so there's nothing wrong." Sometimes things are psychosomatic, but that should be the last avenue explored, not the first 😉
Growing a backup brain is an odd thing that might be impossible because we don't really know how consciousness works. Even if you grew a brain that was identical to your own brain would it still be you? Like if you remove your old brain and replaced it with the new identical one that person might have your memories and personality but you might not be aware of it, in other words the new brain is just another person in your body and not actually you. It would be hard to confirm this as if you ask this new person they would say it is you but that's only because they have your personality and memories.
The new brain would be malleable like an infant's brain and their natural proclivities would just impose onto your consciousness. In short, you'd be you and them But they're an infant mentally so you'd take over the young brain. You'd be you 2.0.
@@aftersexhighfives malleable or not that doesn't really mean anything. You are you, you're conscious you can see out of your own eyes but not others, If someone successfully cloned your brain and implemented it inside you after you died there would be no way to tell if it is actually you or just someone who thinks they are you. You (the old you) may not see out of your eyes or even control the body just like you can't control other people's bodies or see out of their eyes technically the new you would be an entirely different person that just thinks they are you because they have your personality and memories. If somehow you (the old you) can see out of the eyes and control the body then that would suggest that consciousness isn't directly caused by the brain but is caused by something else, it would suggest that consciousness comes from an outside source (different dimension?) That's where the major problem comes from, there would be no way of knowing as like I said the new you will confirm that it's the old you but how do you know that it isn't simply because of them having your memories and personality. It's really hard to explain what I'm talking about as this is an extremely hypothetical concept the point being is our understanding of consciousness is quite limited, we both know and don't know, we know why we can see, feel, hear etc but not "why." What in our brains makes us aware, why isn't it all just black? Think about it if we need our brains to remember things then why do we remember? Like if when we die we cease to remember due to our brains no longer functioning then shouldn't life be similar to sleep? (Without dreams) Why are we aware?
If basic neural clusters can be cultured, it might help people who have conditions where they are unable to move most of their body and can't communicate with anyone.

As an hard atheist, I wonder if we can influence our thoughts or are we just perceiving them. If everything is determined by the physical lows (and chemical and so on), then everything is predetermined from the start, isn't it? I might decide now to write this very sentence but can I really? Wasn't it already decided from the start of times? In a sense we are only a witnesses of our thought process. I know this is a known theory which has it's name but the more I thing about it, the more sense it makes. By that thesis also, if we would somehow grasp all the knowledge about how "things work", we might as well know what will happen in the future. Makes sense?
29:53> not that difficult - unimpeachable science says that mice need the same nutrients as humans as do all backboned creatures. if it good for the mouse - it is as well for the human. the mighty mouse & the somewhat mighty human are still the same. btw 90+1 are virtually the number of nutrients required if not literally, okay, the +1 is cholesterol, get as much as i can and i feel somewhat like the mighty mouse of the cartoon. keep the science coming and be the good hand. thank you SciShow Psych.
A philosophical question about the morality of experimentation: Are we just the compilation the billions of cells in our body collaborating in a common cause to unite as a consciousness/sentience? Or are we individual beings beyond the bounds of 4D time and space only altering and manipulating the lifeforms that compile our bodies as a tool/vessel until we move on after death, leaving the organic material as we transcend into a higher or different dimension? I tend to question everything and don't like to be firm in one belief or the other, but I like to believe in the latter; an individual renting my body rather than the collective of the body itself. After all, most of what we know is minuscule among the vastness of the unknown, which the more I begin to know, the more I realize the less I truly know.

What is going on with the number of compilations you're doing lately?! I have been watching you for years, I have seen this stuff before. Since you've done your rebranding, something like 50% of your programming has been old data. I am a scientist, I want to see new science. I'm not asking you to stop doing them completely. This viewer is getting bored! If people want to see your old shows, they can go directly to your channel
I’m totally speculating, but maybe they’re preparing a bunch of new content (it’s certainly an appropriate time of year for that), and they don’t want to “go dark” in the meantime, since releasing fewer videos risks the wrath of the TH-cam algorithm. They could also be trying to bring in new viewers, especially to the other SciShow channels, and/or to boost conversion of occasional viewers into channel subscribers. I’d imagine that compilations serve a similar purpose as network TV reruns used to when they were still a thing. I also wonder if the COVID of it all has something to do with it, like by slowing down production of new content or causing a drop-off in Patreon member support. But like I said, I’m speculating. 🤷🏽♂️
It only superficially looks like a brain because folding like that was somehow advantageous to it. It is, like all corals, a colony organism, and each individual organism has very little brain to speak of... I highly doubt there's going to be much in the way of communication between colony individuals. Perhaps the folding aids in propagation: the folds maybe make it easier for sperm and egg to meet in the water, or something. Or, maybe the shape helps the coral survive wave-action: it's low and rounded, the wrinkles could break up water movement into little eddies, possibly causing less damage than a larger wave, who knows? A computer model could test that. Or there may be no real reason for it at all. You're trying to make completely different organisms function the same way you do when they evolved for a very different environment and purpose. Similarity in shape doesn't always translate to similarity of purpose.

That being said, you can indeed make new neutral pathways to make up for the ones lost, but that's changing how your brain works, to compensate for the lost cells, not actual healing. It's absolutely amazing, and fascinating, just very different from how surgical healing works on the rest of your body.
@@Amarianee from my research new brain cell generation not regeneration of old cell but generating new ones has been shown with something as simple as thc/cbd tinctures.. may want to look into it.. it's a certain cannabinoid that they can isolate ... also , not legal here but I've heard, not seen study or read publishing that stem cell and something from cord blood " helped" regeneration . I commented before reading all your comment. I'm sincerely not trying g to troll or be bothersome.. just bored really and I've been struggling since 2012 with trying to rewire my brain after an incident left me in hospital for a few weeks .. I left "different " and I've been trying to learn why.. my memory pre 2012 is nearly wiped but now I take information in at a crazy rate .. my wife and mom says my speech has changed and I know somethings changed .. ironically in my case I think for the better although.. who knows
This presenter is great. Well done 🎉👍
If a neurologist and I fall in love, I'm probably going to propose, "Let me be your glial cell!?"
What's in my brain? Minor brain damage. Always been straight edge, because I LOVED my brain as a kid/teen and still constantly pursue knowledge...then they found one of the rarest tumors in the world, in 2008 when I was 19. No rhyme or reason, just one of those random situations, and was so slow growing, it had probably started years ago (it was 2 in when it was found). Treated that gray matter so good, and it betrayed me, just my luck 😒
symptoms? how it affect you?
@@arzelzon1137 I'm now epileptic (controlled with meds though, another bit of good luck) and, for a while, my short term memory was severely impacted. That got better over time, but it took a good 3yrs before it was back to "normal." Normal for _me_ was above average. I used to be able to recite movies/quotes verbatim after watching anything, but now it's pretty average. I also get migraines a few times a month, whereas I used to only get them 1-3 times a year. I got off pretty easy compared to others I've met, and especially considering how large the tumor was, right in the center (it was blocking the third ventricle, causing spinal fluid to build up). We didn't have time to do a biopsy because the pressure would have killed me in a week, tops, so the neurosurgeon was basically going in blind. Luckily, it ended up being gelatinous and was able to be suctioned, rather than a hard tumour, which would have required cutting and inevitably more damage. It was also partially cancerous (grade 2 & 3 cells), so I spent about 10yrs getting follow up MRIs, just to make sure it didn't come back. Pineal parenchymal tumor of intermediate differentiation. Spent my 20th birthday in the hospital.
@@arzelzon1137 I'm assuming you meant symptoms post surgery. For anyone worried, the symptoms pre-diagnosis was severe headaches that felt wrong. I've never had a headache like that or since then. It felt like massive pressure built up in my skull...because it is was. The vomiting started as once every few weeks, and progressively got more and more frequent. 3 different urgent care doctors dismissed me and called it, "muscle spasms," "migraines," and, "too much iron in [your] diet." It was an e.r. doctor that pushed for a CT scan because he was concerned he couldn't find anything wrong, despite my symptoms. He literally saved my life. The moral is: you know your body better than anyone else. If you _know_ something is wrong, and the doctors blow you off, put your foot down. You're the patient and whether it's private healthcare or universal, you pay their salary, and it's their job to treat you. Don't let doctors/hospitals push you around, you've got a right to be listened to, and it could save your life.
As a future doctor, thank you for sharing your story. Very insightful. Wish you the best going forward.
@@Richard-tj1yh Of course! After coming to terms with everything, I realized that my situation could help others, so I use it as an opportunity to advocate for patients and people with chronic illnesses. The best thing you can remember as a doctor is, listen to your patients. It's ok to not have an answer. It will always be better to tell someone you're "not sure, but you'll keep trying," rather than, "I can't find anything, so there's nothing wrong." Sometimes things are psychosomatic, but that should be the last avenue explored, not the first 😉
i'm like a microglia, i also eat my problems :')
My brain sure doesn't how it works
Growing a backup brain is an odd thing that might be impossible because we don't really know how consciousness works. Even if you grew a brain that was identical to your own brain would it still be you? Like if you remove your old brain and replaced it with the new identical one that person might have your memories and personality but you might not be aware of it, in other words the new brain is just another person in your body and not actually you. It would be hard to confirm this as if you ask this new person they would say it is you but that's only because they have your personality and memories.
The new brain would be malleable like an infant's brain and their natural proclivities would just impose onto your consciousness. In short, you'd be you and them But they're an infant mentally so you'd take over the young brain. You'd be you 2.0.
@@aftersexhighfives malleable or not that doesn't really mean anything. You are you, you're conscious you can see out of your own eyes but not others, If someone successfully cloned your brain and implemented it inside you after you died there would be no way to tell if it is actually you or just someone who thinks they are you.
You (the old you) may not see out of your eyes or even control the body just like you can't control other people's bodies or see out of their eyes technically the new you would be an entirely different person that just thinks they are you because they have your personality and memories. If somehow you (the old you) can see out of the eyes and control the body then that would suggest that consciousness isn't directly caused by the brain but is caused by something else, it would suggest that consciousness comes from an outside source (different dimension?) That's where the major problem comes from, there would be no way of knowing as like I said the new you will confirm that it's the old you but how do you know that it isn't simply because of them having your memories and personality.
It's really hard to explain what I'm talking about as this is an extremely hypothetical concept the point being is our understanding of consciousness is quite limited, we both know and don't know, we know why we can see, feel, hear etc but not "why." What in our brains makes us aware, why isn't it all just black? Think about it if we need our brains to remember things then why do we remember? Like if when we die we cease to remember due to our brains no longer functioning then shouldn't life be similar to sleep? (Without dreams) Why are we aware?
Great way to think out of the box.
We aren't dumber as a species? Could have fooled me.
You just blew my mind, microglia girl.
Fabulous, thanks.
If basic neural clusters can be cultured, it might help people who have conditions where they are unable to move most of their body and can't communicate with anyone.
Me after clicking onto this video: oh **** I forgot my brain
Actually this makes total sense one side you prioritize complexity on the other efficiency. The survival rate of said animal would increase.
So, what's the evidence that we didn't become dumber since inventing stone tools? Maybe stone age human will perform better if he was raised in our environment.
A stone age human would run away and live in the middle of nowhere 😂
@@nyuex1317 Stone age is a social characteristic, not a genetic one. Many people who live today in cities, were living in tribes (stone age basically) just several generations ago.
I have trouble sleeping and it always _feels_ like my brain is cluttered, or like it doesn't ever get a chance to "clean house."
I wonder if in the future, we could regrow parts of a dying brain the same way we attach the tissue to mice

The entire Pinky and the Brain mini show that happened in animaniacs was a complete misdirection considering the definition of insanity is trying the same thing over and over and over again getting the same result and still doing it over and over and over again hoping for a different result.
Also Pinky and the Brain one is a genius the other's insane even in the theme song it states that pinky is the genius and the brain is insane.
I love that dress on you! You look amazing!
I clicked on this video and I do not have a brain. Is this where I get one? I heard they're useful.
Some of the youtubers I watch use smooth brain as an insult and it's kind of hilarious.
Glia begin as embryos!? Do other cells begin as embryos? (Maybe I don’t get what an “embryo” is.)
There was a study I read about where baby mice had their brains inoculated with human embryonic glial cells. The mice showed more intelligence than normal mice.
It actually were astrocytes, and yes, they quickly spread through their brains and their intelligence increased.
When Anthony said “we all know that chicks use their right hemisphere too…”
I was like woah, am I about to get dating advice?
As an hard atheist, I wonder if we can influence our thoughts or are we just perceiving them. If everything is determined by the physical lows (and chemical and so on), then everything is predetermined from the start, isn't it? I might decide now to write this very sentence but can I really? Wasn't it already decided from the start of times? In a sense we are only a witnesses of our thought process. I know this is a known theory which has it's name but the more I thing about it, the more sense it makes. By that thesis also, if we would somehow grasp all the knowledge about how "things work", we might as well know what will happen in the future. Makes sense?
Have you read Mark Solm's "The Hidden Spring"? Lots of food for thought...
@@silviopina_111 thnx, will check it out
@@silviopina_111 The spring is not God, right? :)
@@AnteBrkic 😂 nope. It's the brain stem. And "affect" (a.k.a. feelings) are what kickstarted consciousness. It's way cool, check it out.
29:53> not that difficult - unimpeachable science says that mice need the same nutrients as humans as do all backboned creatures. if it good for the mouse - it is as well for the human. the mighty mouse & the somewhat mighty human are still the same. btw 90+1 are virtually the number of nutrients required if not literally, okay, the +1 is cholesterol, get as much as i can and i feel somewhat like the mighty mouse of the cartoon. keep the science coming and be the good hand. thank you SciShow Psych.
A philosophical question about the morality of experimentation: Are we just the compilation the billions of cells in our body collaborating in a common cause to unite as a consciousness/sentience? Or are we individual beings beyond the bounds of 4D time and space only altering and manipulating the lifeforms that compile our bodies as a tool/vessel until we move on after death, leaving the organic material as we transcend into a higher or different dimension?
I tend to question everything and don't like to be firm in one belief or the other, but I like to believe in the latter; an individual renting my body rather than the collective of the body itself. After all, most of what we know is minuscule among the vastness of the unknown, which the more I begin to know, the more I realize the less I truly know.
Did anyone else get a giggle from "We know that chicks use their left hemisphere for..."?
amazing!
Less connection good for tests and if you already know where your going but what about figuring out the unknown (unconnected)
Not quite sure there's a brain in here, would need a scan to confirm.

What is going on with the number of compilations you're doing lately?! I have been watching you for years, I have seen this stuff before. Since you've done your rebranding, something like 50% of your programming has been old data. I am a scientist, I want to see new science. I'm not asking you to stop doing them completely. This viewer is getting bored! If people want to see your old shows, they can go directly to your channel
I’m totally speculating, but maybe they’re preparing a bunch of new content (it’s certainly an appropriate time of year for that), and they don’t want to “go dark” in the meantime, since releasing fewer videos risks the wrath of the TH-cam algorithm. They could also be trying to bring in new viewers, especially to the other SciShow channels, and/or to boost conversion of occasional viewers into channel subscribers. I’d imagine that compilations serve a similar purpose as network TV reruns used to when they were still a thing. I also wonder if the COVID of it all has something to do with it, like by slowing down production of new content or causing a drop-off in Patreon member support. But like I said, I’m speculating. 🤷🏽♂️
Microglia are zombies? Braaaaaaaaains
Look at polyps and their tentacles and reason for brain wrinkles wonder if brain coral functions as an actual brain
It only superficially looks like a brain because folding like that was somehow advantageous to it. It is, like all corals, a colony organism, and each individual organism has very little brain to speak of... I highly doubt there's going to be much in the way of communication between colony individuals. Perhaps the folding aids in propagation: the folds maybe make it easier for sperm and egg to meet in the water, or something. Or, maybe the shape helps the coral survive wave-action: it's low and rounded, the wrinkles could break up water movement into little eddies, possibly causing less damage than a larger wave, who knows? A computer model could test that. Or there may be no real reason for it at all. You're trying to make completely different organisms function the same way you do when they evolved for a very different environment and purpose. Similarity in shape doesn't always translate to similarity of purpose.
@@DrachenGothik666 yeah i thought of all those possibilities but looking at polyps. And their tentacles reminds me of neurons

I don't know if my little brother has ever returned to eat kraut and weiners again, let me explain when we were kids mom made it not all the time but on occasion this one time she made it and he was getting sick and after he was and after that, he never did eat it again, yes he thought that made him sick also my mo never did eat chicken when she was little she spent the night with one of her friends and had dinner with them she did get sick she never did eat it again but she did cook it thoroughly though I do the same.
My ex's son has the same association with chili because he was sick one time when he had it.
I feel like the easier life becomes the less intelligent we will become on the future
