So, your brain decided that your brain is its favourite part of the body, but then your brain thought about what part decided this and now your brain doesn't trust your brain.
You have no idea how reassuring it is to hear that I'm not going to significantly lose my ability to learn as I become an adult! I think that's been one of my greatest fears throughout my life.
Something important that you forget: You have work tomorrow, it's your recitative's Birthday / Wedding and some other incredibly important day. Something irrelevant: That annoying tune you can't get out of your head. XD
this is oddly motivating as it says that we can change our brain be smarter , be better , healthier habits etc and make us realize why it is hard to get rid of bad habits that we been doing for months/years
The entire video focused on learning on a strictly intellectual level (school) but I think its important to note than it also effects physical learning (motor development). Sports for example can create numeral synapses which allow a person to excel at hitting a baseball, throwing a football, or throwing a quick jab etc. Also works for skill trades or art. Anything (everything) that requires practice.

This is one of the most important knowledges you can have and accept. Plasticity is very critical to the progress of humanity.
DeathlordUSA Wrong, ingesting a significant quantity of ethanol is going to reduce your potential lifespan. I'm not saying that you shouldn't get drunk or drink at all, but if you choose to, you shouldn't then try and say that what you're doing isn't damaging to your body.
You guys are seriously amazing people. I'm sorry I don't have any money to give you guys (I'm not an adult yet) but I completely support you guys and please keep making videos :).
Fantastic stuff to know! I find that when I'm researching a topic for a new video on my channel or for my own personal curiosity, I crave that knowledge, and want to fill in as many of the gaps as possible, which usually leads to repetition in studying the material to reinforce my memory and understanding of the subject matter! The brain is AWESOME!
SciShow What exactly is the phenomenon called 'old man strength' where men who otherwise have passed their physical prime years (16-24ish) are suddenly so much stronger than they were in their younger days without putting on that much muscle? What is the science behind it and why does it happen?
I recall it being because we actually use only a fraction of the power our muscles actually possess, as you could easily damage and wear them out otherwise. However you can bypass this limitation by for example panic and adrenaline (explaining stories of moms turning over cars crushing their children and other disaster-related "superpower") or by training up a strong muscle memory, the latter being the reason why old men and well-trained but not exactly muscular martial artists can punch far over their size so to say.
Have you done an episode on the way a person's brain works if they have an autism spectrum disorder? If not, would you be willing to do an episode on this topic? I recently discovered that I have a moderate form of Asperger's Syndrome and would love to know more about how my brain works in comparison to a normal brain. Thanks! -Aaren S.
I thought you were gonna tell me my brain is literally made of plastic. I was like OH MY GOD REALLY? I am now disappointed. But not very, because I didn't know about synaptic pruning before, and that's pretty damn cool.
LtheprodigyH I thought we would find out that plastic can be biologically degradable so there's hope for the environment. That would have been a pretty nice surprise.
2:21 What you say here seems to imply that the "knowing" of a thing is fairly independent from the actual synaptic connections which lead to that knowledge. That seems odd to me. Am I misinterpreting something?
While you are on the topic of the brain, I noticed you don't have a video to explain the science on Hyperbaric Oxygen Treatment (HBOT) effects on the brain. I love the way how you put your video together and I think this will be helpful to many veterans with TBI, PTSD, etc...
Would you make a video on neural imaging devices like fMRI's, and others? what about a video on the different models and theories around memories, or should I expect this from Crashcourse psychology first?
Computers that can rewire themselves for different tasks are currently in the works. A few years back I read about the start of such research, so it'll be a while before we have anything major to show for it.
AAN (Artificial Neural Networks) are a field of AI which work more or less the same way the brain's neurons work. Except it's all software based rather than hardware.
Zukaro Travon Neural networks aren't really like this, though. They have neurons that are static in their connections, and we change only the weights of the synapses. We don't add or remove any connections. Although perhaps you could say that setting a weight to 0 is removing it and changing it from 0 to another value is adding it... it's similar, but not identical. Also, neuromorphic chips implement NNs in hardware, so they're not always software based these days.
I'm a bit confused. Now, that's OK--I've gotten used to the feeling. But if someone could help me out here, I'd appreciate it. At about 2:16 he says it's OK that you have fewer synapses than when you were three because "Now you know that pigs go 'oink'." But where is that "knowledge", if not in the synaptic connections? I understand the pruning of unused synapses, but aren't you using the synapses to know that pigs go 'oink'? If those synapses get pruned, how do you still remember what the pig says? And what's going on with the synapses that tell me what the fox says? (Oh yeah, he covered that in a different video. Never mind.)
Your brain tucks it away so you don't have to keep thinking about it, or else you would be focusing too much on small tasks like remembering how to breath or swallow.
flyingpnda247 "Tucks it away" where? I don't mean to be argumentative. I just really don't know. Is there a way to store knowledge in the brain without using neurons? Or a way of accessing knowledge stored in neurons without using synaptic connections?
Because they're not theories, they're hypotheses, and they're not supported by evidence. If they had evidence, they wouldn't need the "alternative" qualifier.
Oskar R. Spets And how is Spirit Science a quackery channel? Just because it is different doesn't mean it is wrong. If Thomas Edison was still alive today he would be even more radical then that channel. Also, just because it's called Spirit "Science" doesn't mean that it is your conventional science. Again, "Spirit Science". Not just science, it's spiritual science which requires your heart...as in feeling... not just your brain... as in facts and conventional ideas.
Any findings on what can make the brain more plastic (or flexible?), to allow on-demand capacity to retain more information when we need? What's gingko biloba's role in this? Other than continuously bombarding the brain repeatedly with the same information, any way to keep the brain from degrading synapses, even if we don't use it (to make sure that certain pieces of important information never leave our brain)? How long will it take for the synapse to become "unusable", if the information it's responsible for is not used? Any downsides with knowing too much - like would it impact the useful lifespan of brain cells, or will it make you more tired, because the brain has to keep all those connections active, which supposedly would require extra energy?
I remember reading an article that said that autism could be caused in the womb, and that children with autism have many brain irregularities in several places in the brain, not just one part. It also said that early identification of autism is very important because a baby's brain is still plastic enough for its brain to compensate and be restored. Could a teenager or an adult fully recover from autism as well?
Nathan Brindley "In theory yes a teen or adult could 'recover from autism'," Citation please. I wasn't aware the root cause/s of autism had been discovered.
1:17 isn't that kinda like the end scene of Lucy with the black computer matter weird thing? Anyone agree with me? I don't know that movie was weird...
I know it's icky, but I would really like an episode on head lice. More specifically, on head lice treatments: the good, the bad, and the holy crap people really do that.
I remember a time I managed to get a headache when my 5th grade (graduated HS in 2013) teacher had to teach my class basic geometry without any warm up or way to ease the lession over a few days. and cramming the lessions of perimeter, radius, diameter, and the concept of pi as well in a single afternoon (after lunch I think, so something along the lines of 3 hours).
Oh my god! Do you think, maybe... our brains control everything we do? But then, why would they let us have this conversation?! I'm so confused! It's probably my brain, preventing me from understanding this!
iambored2006 They want us to THINK we have control... but they want us to think they want us to think they have control, and they want us to think they want us to think they want us to... dammit it's a paradox..
I always feel like I learn something new when I watch SciShow but since no one talks to me about it and I never actually need to use the knowledge I probably don't remember any of it...
Your teacher is awesome. Scishow videos are high quality and engaging. If you don't like this topic, they have videos on literally every area of science
Love the video... i was a drug addict for 12 years and have been sober for almost two years, I've been studying various sciences for a few months and have a hard time retaining the information I want to retain. So are you saying that all brains will act this way or am I and other addicts just screwed?
Poor Billy Black. The world must have mistreated you so badly that you lack all self confidence, because anyone with any level of self respect wouldn't lash out at others for something so irrelevant. Of course, you'll get a few likes, because this is youtube after all. "Get a sense of humor," you probably will reply. "Get an intelligent sense of humor," would be my response.
So what happens when you've done something a certain way, 2years ago. But you just can't remember, although you are trying to. Did you lose the synapses? Of what is your brain doing when you try to remember something? Thanks!
So then how do brains the remember everything function differently from a normal brain? I have a friend that remembers everything ever experienced by him, so how does that differ from the norm?
If I took care of my brain wouldn't that just be my brain taking care of itself...great thinking about this makes my brain hurt and everything smells like copper now
The thing that I always thought was really fascinating about brain plasticity is that in 10 years time, you can use it to completely rewire your skill set. You can turn yourself from an expert engineer into an expert artist. The other really neat thing is how this plays into drug use and damage to the brain. in 10 years it can completely rewire itself to function normally again. This is rather simplified, but if you're under a constant drug effect that doesn't damage your brain, after 10 years it will be like you were never on the drug to begin with. Lose a section of your brain dedicated to sight? In ten years your brain will have repurposed another part of it to take care of sight. This is also why if you lose the ability to see, your other senses get sharpened, since your brain has repurposed the vision sections to focus on other things.
alexthesin3 actually No... brains cannot retain an infinite amount of information... partly because there is a physical limit to it's "growth" and association. And another part because the brain has mechanisms to essentially force itself to forget stuff. Especially if information isn't reinforced and or oft used.
DevTheBigManUno I think he meant the internet. But that's not true as well, even if we used every atom in the universe (which there /probably/ is a limited amount) to make memory chips, it would still be limited amount of information, albeit very huge.
Depends on what the religion is used for. For example, some civilizations in ancient Mesopotamia used religion to unify their people and as a primitive form of law enforcement. Other uses of religion like Westboro Baptist Church and Scientology, however, are completely stupid and make me feel pain on the inside because they exist.
Solid Structure your short-sighted ignorant view of science is disgusting. Were not in the dark ages get your head out of your ass and at least look at the other side with an open mind.
Since we're talking about brains so much, can we get a more detailed brain plasticity video? Like how if you wear glasses that flip your sight upside down, your brain adjust and flip that image to where it appears right-side up. Then it can actually flip back when you remove the glasses for a couple days.
Can you talk about if our brains run out of space over time? I know you said we grow new neural connections and stuff, but there is a limit to how much we can know, right? Talking from personal experience, I can only know 2 languages well. English is my first language, and I've noticed that if I know a second language and then study a 3rd language, I am constantly mixing up grammar and vocabulary from the 2nd and 3rd. And not only that, the more of a 3rd language I learn, the more of the 2nd language I forget. It's very frustrating. :(
That's false. I think that maybe you should put time into getting fluent in a second, then pick up a third. By the time you're fluent your brain won't be making mistakes like that, and you can go ahead and add a new one. Another important thing is using it everyday, so it doesn't fade. Also, there are people like Luca Lampariello, who have been learning languages since they were young, and speak over 10 languages fluently, most of them added after they were a kid. Don't give up! Push on! Visit reddit.com/r/languagelearning
Your brain doesnt store data in a way that can really "fill up" Imagine a 3D structure that can read differently depending on where you start. From one corner through its a memory about you skiing, from the other corner the same neurons give sensation of you eating a bowl of cereal, with millions of different combinations. Only the connections that are used repeatedly are kept, the rest shrink and thus open up new opportunities for new connections to be made in their place. In other words, You don't use the languages frequently enough for you to keep them.
Learning language is best done from starting from very early in age, by the time you are an adult if you havent even had experience learning a new language it will be difficult to pick a new one up.
Speaking from my own experience, learning multiple languages can be difficult. In addition to the skills in learning the new language itself you also need to improve your techniques for controlling which language you're speaking. Something you never had to learn with just speaking one language. Getting confused between languages can be common when you first start, however it doesn't continue forever. Gradually you learn the skill of handling all the languages that you know. The important thing is to continue practicing and to find opportunities to speak the languages you know. The more you use these skills, the better your brain will adapt. If you've stopped using your second language while you're focusing on learning a third, it's only natural for you to start forgetting some of what you know. Keep it alive by finding opportunities to use your different languages. Many cities will have language clubs where you can meet other polyglots and speak with them. These days as well, the internet offers amazing opportunities to find people on Skype to practice with.
So thats how your brain learns like technically... but are their any suggestions of best way to get your brain to remember the information it learns like for tests or everyday use? For example I heard if you write something in blue ink you are more likely to remember it
this video just made me think that all technology aspires to be like the human brain (eventually). but truly there is no tech that's even close to being as advanced/ dynamic as our brains.
I really appreciate your your video!!! I'm curious why your explaining it sooo fast. Great info, however I wish you spoke a bit slower for my students.
I'm not sure but I think that there is too much force when you decelerate on the way back down for it to be deemed safe or comfortable. It could also prevent blood form reaching your brain for a second and cause problems for some.
One thing I think is important to mention but maybe not relevant to the topic of this video is that your axons are protected by myelin sheaths. These will weaken over time (even faster by playing video games and watching too much TV) but they can also be strengthened. Why would you want to do this? Well the weakening of the myelin around your axons leads to poor memory, dementia, and Alzheimer's. There are more neural connections in your hand than any other part of your body. You can use that information to partake in a process called myelination. While memory exercises such as memorizing numbers help with this process, exercises involving fine motor skills of the hands ambidextrously will supercharge myelination. Exercises such as ambidextrous penmanship (that means forward and mirror-imaged with both hands) and bouncing a golf ball off the head of a hammer have all sorts of benefits for the brain. If you're interested in taking the strength of your brain (and as a result, your body) seriously, google "Whole Brain Power"
The slight niggle I have with this description is that it lends itself to a static conclusion, 'memory'. Maybe an addendum vid would touch on the plasticity of memory itself?
The brain was my favorite part of the body, then I thought about what part decided that and now I don't trust it.
this is such an underrated comment im so disappointed in this community
Bias opinion I’d say.
So, your brain decided that your brain is its favourite part of the body, but then your brain thought about what part decided this and now your brain doesn't trust your brain.
@Dusten Blythe underrated means it doesn't have enough attention bruv.

You have no idea how reassuring it is to hear that I'm not going to significantly lose my ability to learn as I become an adult! I think that's been one of my greatest fears throughout my life.
I let out a sigh of relief too! Phew lol
GG, that bullshit the narrowminded popcultists say is indeed bullshit as one rationalized!
As long as you work your brain to keep forming connections (promoting your brains own plasticity), you should be fine lol
well i didnt like school any ways
well, to add, the reason this idea propegated migth ahve something to do with the mind being more openminded as a young person.
My brain:
Something important: FORGET
Something irrevelant: REMEMBER FOR YOUR WHOLE LIFE

Too true. 😂

Math formulas for an important exam tomorrow: FORGET
Something embarrassing I did 10 years ago: REMEMBER LIKE IT HAPPENED YESTERDAY
this is oddly motivating as it says that we can change our brain be smarter , be better , healthier habits etc and make us realize why it is hard to get rid of bad habits that we been doing for months/years
The entire video focused on learning on a strictly intellectual level (school) but I think its important to note than it also effects physical learning (motor development). Sports for example can create numeral synapses which allow a person to excel at hitting a baseball, throwing a football, or throwing a quick jab etc. Also works for skill trades or art.

Part of my thesis was about this, and man was it hard to find information. Glad this area of science is developing!
Drinking large quantities of alcohol is also called synaptic pruning.
DeathlordUSA Wrong, ingesting a significant quantity of ethanol is going to reduce your potential lifespan. I'm not saying that you shouldn't get drunk or drink at all, but if you choose to, you shouldn't then try and say that what you're doing isn't damaging to your body.
styk0n hey, fool. he literally JUST said that.
marshall ling tell me more about him saying what I just said.
DeathlordUSA well drinking 8 ounces of alcohol a day is said to add 30 minutes to you life but drinking more than that drastically reduces it.
DeathlordUSA Look up Micromorts and Microlifes.
I have pruned so many synapses in my 52 years. ( 2:17 Synaptic pruning.... )
SciShow is so helpful in keeping my brain plastic. Thank you, SciShow.
Please do more videos on the brain there's always new stuff discovered all the time and you make everything intriguing keep up the good work!
Scishow could not do the complexity of the brain the justice it deserves. But yes they should do more with it(:
You should check out Hank's Psychology series on Crash Course. It's very interesting.
Shattered Anvil good idea I haven't watched crash course in ages
I should have gone to bed an hour ago, but then, SCIENCE!
Looks at title of video...*oh god*
They finally found out.
:D
Hello
I ALSO know why it took us so long to find out why our brains are made of plastic...
Because our brains didn't want us to know
*****
Because it used to be made of natural materials but everyone decided to go cheap.
Hank, you are my favorite person on TH-cam. Keep up the great work
Thank you SciShow for all the synapses :)
You and your crew are a gift. Keep it coming.
Every new information I learn takes the room of an old information.
That is why I forgot how to drive after a wine tasting course.

With muscle memory basically being about firing off stronger nerve signals = more ions released in the muscle = stronger contraction = more strength.

They did a story on fecal transplants, so I'd say that lice is not too icky a subject for them to cover.
Point taken.
Hank would be the most awesome teacher ever
Keeping that brain active is also a great way to stave off Dementia and Alzheimer's later in life.
I remember a time I managed to get a headache when my 5th grade (graduated HS in 2013) teacher had to teach my class basic geometry without any warm up or way to ease the lession over a few days. and cramming the lessions of perimeter, radius, diameter, and the concept of pi as well in a single afternoon (after lunch I think, so something along the lines of 3 hours).

iambored2006 They want us to THINK we have control... but they want us to think they want us to think they have control, and they want us to think they want us to think they want us to... dammit it's a paradox..
This is similar to search for intelligent life in universe, while forgetting that "intelligence" is human made concept ;)
WMTeWu Actually, it isn't. Intelligence isn't a human-made concept, it's a human-communicated description of behaviors.
Cute Anime Person
What kind of behaviors?
Why don't the Inner Transition metals react with anything to form compounds?
You should do a video on autism
I always feel like I learn something new when I watch SciShow but since no one talks to me about it and I never actually need to use the knowledge I probably don't remember any of it...
My teacher is making me watch this I don’t want to be here send help
same here...
Me too
i gotta watch 4 more videos like this :(
@@ms.bobatotes3945 R.I.P. man
Your teacher is awesome. Scishow videos are high quality and engaging. If you don't like this topic, they have videos on literally every area of science
you know im really quite curious... how does an app, or phone or computer for that matter CRASH? what is CRASHING?
And this is how to create a decent sponsored video.
Love the video... i was a drug addict for 12 years and have been sober for almost two years, I've been studying various sciences for a few months and have a hard time retaining the information I want to retain. So are you saying that all brains will act this way or am I and other addicts just screwed?

My brain is polyethylene terephthalate.
As a person with a brain injury I thank science every day for plasticity. Brain allowing me to relearn to walk.
there needs to be a scishow the helps explain and remove the mole on his neck
Ass.
But then he wouldn't be the same Hank anymore.
Poor Billy Black. The world must have mistreated you so badly that you lack all self confidence, because anyone with any level of self respect wouldn't lash out at others for something so irrelevant. Of course, you'll get a few likes, because this is youtube after all. "Get a sense of humor," you probably will reply. "Get an intelligent sense of humor," would be my response.
... Now I will never be able to see him without the mole...
Damn you I can't stop looking at it!! XD
Can you explain the science of heartache the physical and mental aspects?
WHAT!? PEOPLE STILL EXIST WHEN YOU CAN'T SEE THEM?
NOt unless you think about them. :)
So what happens when you've done something a certain way, 2years ago. But you just can't remember, although you are trying to. Did you lose the synapses? Of what is your brain doing when you try to remember something? Thanks!
I'm now going to spend 10+ minutes replying to everyone on this page.
good grief.
i feel you
you missed one ;P
Fucking nailed it.
So then how do brains the remember everything function differently from a normal brain? I have a friend that remembers everything ever experienced by him, so how does that differ from the norm?
If I took care of my brain wouldn't that just be my brain taking care of itself...great thinking about this makes my brain hurt and everything smells like copper now
The thing that I always thought was really fascinating about brain plasticity is that in 10 years time, you can use it to completely rewire your skill set. You can turn yourself from an expert engineer into an expert artist.
The other really neat thing is how this plays into drug use and damage to the brain. in 10 years it can completely rewire itself to function normally again. This is rather simplified, but if you're under a constant drug effect that doesn't damage your brain, after 10 years it will be like you were never on the drug to begin with. Lose a section of your brain dedicated to sight? In ten years your brain will have repurposed another part of it to take care of sight. This is also why if you lose the ability to see, your other senses get sharpened, since your brain has repurposed the vision sections to focus on other things.

so meta
"Occasionally" remind you where your phone is but always synaptic pruning the location of your keys.
So brain is kinda like the internet, just smaller?
Yes, except that it's not blocked in certain countries.
@Lydia: Unless you live in North Korea.
It can retain an infinite amount of information! I woulds say it is larger in that sense. xD
alexthesin3 actually No... brains cannot retain an infinite amount of information... partly because there is a physical limit to it's "growth" and association. And another part because the brain has mechanisms to essentially force itself to forget stuff. Especially if information isn't reinforced and or oft used.
DevTheBigManUno
I think he meant the internet. But that's not true as well, even if we used every atom in the universe (which there /probably/ is a limited amount) to make memory chips, it would still be limited amount of information, albeit very huge.
Great, now my brain is different. Thank you, Scishow!
Hey Brain,
I love you!
-me
Basically, your brain just told your body to tell itself that it loves itself... Brainception....
oohhh snap! get out of my head you! ;)
So funny you very nearly killed me.
Literally. I was eating. I nearly chocked.
Congratulations. You nearly made a man laugh himself to death.
Do personally disorders make it harder to retain memories and/or learn new ones?
Science is beautiful, so is the human brain... until it meets religion.
Depends on what the religion is used for. For example, some civilizations in ancient Mesopotamia used religion to unify their people and as a primitive form of law enforcement. Other uses of religion like Westboro Baptist Church and Scientology, however, are completely stupid and make me feel pain on the inside because they exist.
Science is a lie. We've never seen the big bang. Only god is real. God was there since the beginning. Only Christ is truth.
Solid Structure your short-sighted ignorant view of science is disgusting. Were not in the dark ages get your head out of your ass and at least look at the other side with an open mind.
I hope you know it's a troll...
765Alpha Well, if this was a video about religion, there is a big chance you would see comments like that even without trolls:D
Since we're talking about brains so much, can we get a more detailed brain plasticity video? Like how if you wear glasses that flip your sight upside down, your brain adjust and flip that image to where it appears right-side up. Then it can actually flip back when you remove the glasses for a couple days.
Can you talk about if our brains run out of space over time? I know you said we grow new neural connections and stuff, but there is a limit to how much we can know, right?
Talking from personal experience, I can only know 2 languages well. English is my first language, and I've noticed that if I know a second language and then study a 3rd language, I am constantly mixing up grammar and vocabulary from the 2nd and 3rd. And not only that, the more of a 3rd language I learn, the more of the 2nd language I forget. It's very frustrating. :(
That's false. I think that maybe you should put time into getting fluent in a second, then pick up a third. By the time you're fluent your brain won't be making mistakes like that, and you can go ahead and add a new one. Another important thing is using it everyday, so it doesn't fade. Also, there are people like Luca Lampariello, who have been learning languages since they were young, and speak over 10 languages fluently, most of them added after they were a kid. Don't give up! Push on! Visit reddit.com/r/languagelearning
Your brain doesnt store data in a way that can really "fill up" Imagine a 3D structure that can read differently depending on where you start. From one corner through its a memory about you skiing, from the other corner the same neurons give sensation of you eating a bowl of cereal, with millions of different combinations. Only the connections that are used repeatedly are kept, the rest shrink and thus open up new opportunities for new connections to be made in their place. In other words, You don't use the languages frequently enough for you to keep them.
Learning language is best done from starting from very early in age, by the time you are an adult if you havent even had experience learning a new language it will be difficult to pick a new one up.
Speaking from my own experience, learning multiple languages can be difficult. In addition to the skills in learning the new language itself you also need to improve your techniques for controlling which language you're speaking. Something you never had to learn with just speaking one language. Getting confused between languages can be common when you first start, however it doesn't continue forever. Gradually you learn the skill of handling all the languages that you know.
The important thing is to continue practicing and to find opportunities to speak the languages you know. The more you use these skills, the better your brain will adapt. If you've stopped using your second language while you're focusing on learning a third, it's only natural for you to start forgetting some of what you know. Keep it alive by finding opportunities to use your different languages. Many cities will have language clubs where you can meet other polyglots and speak with them. These days as well, the internet offers amazing opportunities to find people on Skype to practice with.
Wow, I'm learning about learning :D thank you Hank Green!
could synaptic pruning have anything to do or associate with dreaming?
So thats how your brain learns like technically... but are their any suggestions of best way to get your brain to remember the information it learns like for tests or everyday use? For example I heard if you write something in blue ink you are more likely to remember it
what colur would a synaps be if you scaled it up to a foot a cros
this video just made me think that all technology aspires to be like the human brain (eventually). but truly there is no tech that's even close to being as advanced/ dynamic as our brains.
i don't get it , is it harder to learn mroe as we get older or is it difficult to learn more because of what we've learned in our earlier years?
I really appreciate your your video!!! I'm curious why your explaining it sooo fast. Great info, however I wish you spoke a bit slower for my students.
Why are Rollercoaster loops tear shaped & not circular? Please clarify sciphysics.
I'm not sure but I think that there is too much force when you decelerate on the way back down for it to be deemed safe or comfortable. It could also prevent blood form reaching your brain for a second and cause problems for some.
Do different types of reading, cause different brain activity? Such as reading pop culture v.s Shakespeare.
One thing I think is important to mention but maybe not relevant to the topic of this video is that your axons are protected by myelin sheaths. These will weaken over time (even faster by playing video games and watching too much TV) but they can also be strengthened. Why would you want to do this? Well the weakening of the myelin around your axons leads to poor memory, dementia, and Alzheimer's.
There are more neural connections in your hand than any other part of your body. You can use that information to partake in a process called myelination. While memory exercises such as memorizing numbers help with this process, exercises involving fine motor skills of the hands ambidextrously will supercharge myelination. Exercises such as ambidextrous penmanship (that means forward and mirror-imaged with both hands) and bouncing a golf ball off the head of a hammer have all sorts of benefits for the brain.
If you're interested in taking the strength of your brain (and as a result, your body) seriously, google "Whole Brain Power"
SciShow is awesome. I wish my brain connections weren't faulty so that whatever I learn from videos would stick.
The slight niggle I have with this description is that it lends itself to a static conclusion, 'memory'. Maybe an addendum vid would touch on the plasticity of memory itself?
How do our electronics charge?
by increasing electric potential i the batteries
Very awesome vid🤔..thanks my man!👍😉
I find it hard to retain info is there eney thing I can do other than do the same thing over and over to learn it ?
so, are memories a physical thing?
we don't know where we keep our memories, yet.....
+Vladimir Putin Not adjectives.
Memories are pretty much eletricity that runs through your brain, so yes it is physical but not in the way you think
I don't know why I expected to learn something new here. I've been so obsessed with the brain for the last two years...
