In college our Business trainer wasted a week explaining the "armchair psychology" version of lateralisation. We should have been learning about KPIs and recognising team members' abilities and weaknesses. Instead we did a quiz which tells your "dominant side" and suggests career paths. Considering the facts it's a silly hypothesis. The "strict and analytical" left-side excels at creative and chaotic abstractions. The "artistic and intuitive" right-side diligently keeps track of important time/date classifications.
The split brain thing really intrigues me now, I want to know more, were the personalities of each half always there or did they form after the surgery? The brain which cannot speak, how aware are they of these things, does it cause them pain? A lot of moral questions, is the nondominant side now a new person who's trapped? Can the right brain point at letters to form sentences or is it purely limited to simple yes and no questions?
They're not two different personalities. They're two sets of functions that your brain uses to operate. Think about crossing your eyes. How are you able to see two distinct things at once? How are you able to focus on one eye at a time?
Man, those split brain patients are something else. So fascinating! I wonder if both halves would agree on things like sensations? If you ask them whether they're hungry, will they say/point to yes? Do they both feel the sensation of touch? Crazy stuff
Well the sensory gyrus of the left brain feels sensation on the right side of the body and vice versa. Same with motor gyri. So yeah maybe both consciousnesses don’t feel sensation on both sides.
I have only recently started watching your stuff and I was recommended this video today. I have got to say, with all honesty, the wonder-twin routine at the end was the best. I have not seen something so wonderfully innocent, true, and nerdy in a long time. The last five seconds are perfection.
I've always been perturbed by this myth. I'm fairly gifted academically (at least according to my grades) and I love learning new things, but I also love the arts and creative sciences. Who's to say you have to be one or the other? I want to be everything: excluding athleticism, in which I currently fail horrificly at.
I not only was told in school that being right handed meant you were inherently more analytical and that being left handed inherently made you more creative.
that would mean most people are analytical which is definitely not the case, I don't know how anyone believed it when evidence that disproves it is talking to the nearest right-handed person.
I am definitely what some would call “right brained”. I am left handed and have always had a knack for mathematics and philosophy(particularly metaphysics). However, I compose and produce my own music as a hobby, one of my favorite things to do. I am also exceptionally good at drawing. I find it silly that anyone would find themselves wanting to choose just one side of their brain to represent them or to define what they pursue. If you find something you like, go for it. It doesn’t matter what hand you hold a pen in.
Most people will immediately realise the whole left/right thing is a myth as soon as they've met a few people who are either very logical or very creative. A huge chunk of the people I've met who are extremely logically gifted are also impressive musicians, actors, artists, or some other kind of creative. That alone makes it clear that you're not creative OR logical, but going further, in my personal experience I've found a much greater proportion of very logical people are creative than just average people.
Regarding that extra comment towards the end: I actually always assumed that the whole "only 10%" thing just referred to *active* use, with the remaining 90% being all that subconcious stuff we have no direct control or awareness of.
Can you imagine not controlling half your body, being aware that another 'person' can talk for you without you knowing why, and you both have to somehow share one body? Far out....
i figured out that this is just a pop psychology myth when i realized I’m both a very artistically inclined person, AND science-y person (used to be a big fan of biology and chemistry. really just school in general. that changed…….)
Betty Edwards, author of Drawing On The Right Side Of The Brain, was heavily invested in this theory, but her methods clearly worked. What I don't understand is why, if the underlying premise is incorrect.
Sooo what about dyslexic people? I've heard that we process language in the right hemisphere as a compensation technique that doesn't work that well, hence it being a learning disability. Is that true?
There is a 19 year old girl named Cameron Mott who is actually left brained, but that’s because she got a hemispherectomy (removal of one side of the brain) when she was 3.
My sister got her brain split up because of her bad epilepsy, this is making me question a lot about her behaviour. I'll definitely have to do more research about the effects of the surgery like wtf???
I think that these strange occurrences happen when the two sides are isolated in an experiment. For the most part both sides are receiving the same information and make similar judgments.
I know I am really late to this video, but would love to see a similar discussion of "learning styles" "multiple intelligences" and other similar "poorly explained in Psych 101 class" topics :)
Listened to skeptics with a K podcast the other day and they had a psychologist/ past life regression therapist. She was using the whole left/right brain dynamic in her explanations. She also explained that if evidence came out disproving past lives, she wouldn't stop because she's been doing it for so long.
I have always rationalized the 10% thing as that much at that split second. Sort of to reduce heat generated by the firing neurons, most of us never needs all 100% in the on position at once but in states of on and off. But that is only my own rationalization from watching the fMRI images.
Pretty sure that's the fact that it got misinterpreted from. 10% of the brain at any moment got turned into 10% of the brain at all at some point and noone corrected it.
Thank you. I believed I was ""left brained"" because of my autism, which was troublesome due to the fact that I enjoy creating music, which is allegedly a ""right brained"" activity.
Great video, but I really want to find more information regarding the two hemispheres. When the communication between the two is severed, it shows the presence of another self within ourselves. I want to find research regarding how to communicate with the non-verbal half without being split-brain. I want to explore the idea of getting the halves to work better together, more harmoniously, because I feel like this is an interesting line of thought to pursue. I understand without being split-brain they already have the ability to communicate with each other, but still hold separate beliefs and have different opinions, which I genuinely want to understand in a non-split-brain.
Whenever someone throws out the “we only use 10% of our brains” statistic, my favorite retort is “So you genuinely think if you were shot in the head, there’s a 9/10 chance you’d be perfectly fine?”
In short, it's misquoted from research that generalized as "You only use 10% of your brain /at any one time/.", the last part is what many people do not include, and as such think 90% of the brain is functionless. In reality, because the brain is largely compartmentalized, you only use a fraction of it at any time. Reading, writing, motor functions, lying, remembering, all use different parts of the brain, or more or less intense concentration. So sure at any one time you might only use 10%, basic motor functions and light thought while jogging for instance, but the other 90% isn't a waste, it's there for other things, after all. It's like saying you only use 10% of your car. Sure, maybe I'm only actively "using" the steering wheel and the seat and the pedals, but the windshield is helping visibility, the engine is helping with movement, the wheels are helping with traction, even though you're only "using" a tiny portion at the time, it all gets used eventually.
i loved this video so much. i never believed we were one-sided, and espcially not that we use only 10% ofour brains (which is a common myth everywhere). thnak you guys
This is a very, very good video tending to a younger audience! It is scientifically accurate, which is not a given for many of the videos I’ve reviewed. It is using simple language and is presented slowly, fitting well for younger children. One aspect of improvement, instead of using percentages (over 90%) I’d verbalize them as (the very vast majority of) etc. to simplify even more! Thank you so much!!
This is only partially correct. Iain McGilchrist lays out the functions of the hemispheres in a more technical explanation in his published work "The Master and His Emissary". He goes into depth about the difference between the hemispheres as one being the Master (the right hemisphere) and the other being the Emissary (the left hemisphere). The distinguishing factor has to do with operationalizing in which the right hemisphere is concerned with maintaining overall functionality whilst being "reserved", and the left hemisphere is concerned with actions or impulsivity. There is extensive tests with both side hemisphere stroke patients and it's quite fantastic to go through the discovery.
I guess the statement "you only use 10% of your brain" applies when your brain is in "idle" state, when you aren't thinking of something particular or aren't fully focused to something. Similar to how computer's CPU isn't going to be at 100% all the time
I always thought this idea was bullshit. Another bullshit idea was "learning styles." The idea that there are "visual learners", "auditory learners", or "kinesthetic learners." On the one hand, it might have been useful to break away from previous rigid ideologies about education, it probably was not best practice to replace one bad idea with another bad idea.
Yes, I agree with you. However the ideas of left brain / right brain or auditory, kinesthetic, visual learning styles was taught and believed to be useful and relevant in education and business and many other areas of life. But it's not real.
Except most people respond to similar and varied learning styles that are appropriate for a given topic. That's why so many say they're visual learners - it's just that people crave actually seeing a demonstration of what is being taught rather than hearing about a nebulous concept. Also, people often use the "learning style" thing to excuse bad understanding, like people who want overly-simplified pictoral explanations that are easy to understand but misleading (at least as far as being taken for a full explanation) or people who can follow instructions but lack an actual, deeper understanding of what they're doing.
For anyone interested in a very interesting, albeit intensely dense, book on the intricacies of brain lateralization "The Master and His Emassary" is a good read. I found it to be very enlightening and gave me a lot to think on. (Edit: minor grammar)
Maybe in the future we could wire up the right side of the brain to a speech box of some kind, so we could have someone with a surgically split brain able to communicate to us through both sides of their brain after the split.
Once a guy giving a speech at my school prize giving he talked about it. And he just listed symptoms of adhd. Qnd i felt so bad about myself because he made "right brained" people seem stupid. And being stupid all this time even when my teachers praised me for being smarter than most of my peers. That they were wrong. And all the things I believed about myself were true. Stupid, pathetic, emotional, childish. It made me almost burst into tears :']
Very good info but I remember hearing that this idea might be older than the fifties (though it might have evolved and become a way more prevalent idea by then) and originated around the time when Broca and Wernicke had originally published their famous research on the Broca and Wernicke areas. _The Strange Case of Dr. Jekyl and Mr. Hyde_ is said to have been inspired by this myth and of course, it's publication predates the 1950s (it was published in 1886).
Always felt like this was one of those things everyone talks about like it’s fact but never felt like actual fact to me. I’m very mathematical but also creative so the typical definition of “right and left” brain people just didn’t feel believable to me
I'm autistic. I have an actual ASD diagnosis. So my brain is affected in different ways. My internal hippocampus filter is less efficient for one thing as others. Which makes me more sensitive, especially sound and smell. It's a sensitivity (read suffering) others cannot comprehend even if they believe they do. You don't have to live with my brain, do you? Everybody is sensitive to one degree or another, but definitely not on the autistic degree. And my dopamine transmission is as lost as an ex meth addicts one. I do have a sense of empathy, I'm vegan. But I hate dogs. (Hated them before I was vegan already though, just hated them even more after realizing the hypocrisy, irrationality, dangers and the environmental impact.) Although hating dogs is more of a good thing. At least it's a justified one. I'm also keen to rationality rather then indoctrination, religion, ideologies, following the mass and superstition. Very sceptic, sometimes a bit too much where I highly mistrust others. (although usually with people who have misused my trust in the past or tell plain bs in my face) I also play shakuhachi for example, you don't play shakuhachi if all you do is follow the latest hype. You'll only play it if you're authentic enough to not care too much about blindly following the crowd. Wait, what were we talking about? Right, aRTistic brains myth.
I first learned about the split brain thing from Sam Harris in one of his books... I like to freak people out by telling them all this... And adding at the end "ya know... A person can live and function with only the left hemisphere of the brain... If the right side can have opinions and is a separate consciousness... And objects to being removed... But you remove it anyway... Is that murder?"... And watch em squirm... Lol
I know I'm late to the party but great video Dave! Jewel you were amazing! I have a question about the whole one side of the brain controls the other side of the body, is it any different when someone is cross-dominant? They don't have one dominant hand or side, it's dependent on the task at hand (pun intended) and which hand or side was used to learn the skill first, for instance I write with my left hand, I use silverware with my left hand, I throw with my right hand, I swing a baseball bat right-handed, but after learning I was cross-dominant I taught myself how to weld with both hands, I didn't figure this out until I was about 25 after wondering for years why my dominant left writing hand wasn't my strong arm, it does seem that my left side deals with skills focused on dexterity and balance where as my right side deals with tasks that involve strength and large motions, would love to know what you think about this if you ever read this, thanks Dave! Have a good day, keep up the great work but don't forget to take time for yourself when you need it 😄
Just because we use each side of the brain equally doesn't mean that each side is as proficient as the other. I can think of a wire that's twisting from point A to point B. I can also think of a wire that is going directly from point A to point B without any twisting. Just because both wires start and end at the same point it doesn't mean that they are the same. One is clearly more efficient than the other. I could see how something like this could be similar to the brain where one side might be better at certain things than the other side is good at the things it can do. There's obviously people who are better at math than they are at painting. There's obviously people who are better at painting than they are at math. Just because the brain is used equally doesn't mean that the brain is equally talented. Then again this is just speculation based on what I heard from this video.
I literally took tests only to find out I'm neither right brained not left brained😂The same thing happened when I was a kid and now. I was in the middle. I'm good at drawing and is a creative type of person but I'm also equally interested in Science, logics and all
It is obvious that the suggestion a person is either left or right when it comes to brain function is not to be believed. That being said, my behaviour, interests and skills convince me that my right hemisphere is exercised more than the left. I justify this belief by the recognition that most of the functions of the left brain I avoid as much as is possible. An example would be speech and language, sure I can read and speak but do I? Not if I can avoid it. As a consequence how proficient to you think I am at these tasks? If you run down the list of the things credited to the left hemisphere, they are neglected by me automatically. This belief my not be upheld by an expert in the field of brain behaviour but I am very comfortable and inspired when lost out there pondering the possibilities of anything that my minds eye focuses on and extremely uncomfortable within when I call upon myself to engage in tasks such as this. The lack of skill must be evident but that’s my point. If you exercise one hemisphere and neglect the other I would conclude that the side that automatically draws you is your dominant side.

The split brain thing really intrigues me now, I want to know more, were the personalities of each half always there or did they form after the surgery? The brain which cannot speak, how aware are they of these things, does it cause them pain? A lot of moral questions, is the nondominant side now a new person who's trapped? Can the right brain point at letters to form sentences or is it purely limited to simple yes and no questions?
well they are connected so~
and plus in some cases we can't fully really say "no" and "yes" for something
They're not two different personalities. They're two sets of functions that your brain uses to operate. Think about crossing your eyes. How are you able to see two distinct things at once? How are you able to focus on one eye at a time?
@@EggEnjoyerwooooow chill don't gotta make a whole essay to disagree about something
@@EggEnjoyer when you say "the individual experiences both halves" what is the "individual" you speak of?
@@EggEnjoyer but do you have any evidence of such a thing existing?
What's even crazyer is that the only difference between those splitbrain people and us is that our brain's half communicate..
Man, those split brain patients are something else. So fascinating! I wonder if both halves would agree on things like sensations? If you ask them whether they're hungry, will they say/point to yes? Do they both feel the sensation of touch? Crazy stuff
Well the sensory gyrus of the left brain feels sensation on the right side of the body and vice versa. Same with motor gyri. So yeah maybe both consciousnesses don’t feel sensation on both sides.
I have only recently started watching your stuff and I was recommended this video today. I have got to say, with all honesty, the wonder-twin routine at the end was the best. I have not seen something so wonderfully innocent, true, and nerdy in a long time. The last five seconds are perfection.
I don't know how much of my time I wasted as a student and clinician trying to explain this to people who STILL argue about it.
I've always been perturbed by this myth. I'm fairly gifted academically (at least according to my grades) and I love learning new things, but I also love the arts and creative sciences. Who's to say you have to be one or the other? I want to be everything: excluding athleticism, in which I currently fail horrificly at.
Please make a video on that 10% bs. Please and thank you
not much to make a video on. all you have to say is bullshit and be dome with it.
The fact that I am stupid is not because of half of my brain is not well functioned. I am actually stupid.
I was always taught wrong. Thanks for clarifying this for me Dave. :) I hope to catch more of your awesome and informative videos. ;)
I not only was told in school that being right handed meant you were inherently more analytical and that being left handed inherently made you more creative.
that would mean most people are analytical which is definitely not the case, I don't know how anyone believed it when evidence that disproves it is talking to the nearest right-handed person.
I'm right handed and I'm almost completely creative.
I am definitely what some would call “right brained”. I am left handed and have always had a knack for mathematics and philosophy(particularly metaphysics). However, I compose and produce my own music as a hobby, one of my favorite things to do. I am also exceptionally good at drawing. I find it silly that anyone would find themselves wanting to choose just one side of their brain to represent them or to define what they pursue. If you find something you like, go for it. It doesn’t matter what hand you hold a pen in.
Most people will immediately realise the whole left/right thing is a myth as soon as they've met a few people who are either very logical or very creative. A huge chunk of the people I've met who are extremely logically gifted are also impressive musicians, actors, artists, or some other kind of creative. That alone makes it clear that you're not creative OR logical, but going further, in my personal experience I've found a much greater proportion of very logical people are creative than just average people.
It really sucks to be creative but not logically gifted at all.
For personality tests people sometimes use it a metaphor similar to saying 'follow your heart'
Regarding that extra comment towards the end:
I actually always assumed that the whole "only 10%" thing just referred to *active* use, with the remaining 90% being all that subconcious stuff we have no direct control or awareness of.
Can you imagine not controlling half your body, being aware that another 'person' can talk for you without you knowing why, and you both have to somehow share one body? Far out....
i figured out that this is just a pop psychology myth when i realized I’m both a very artistically inclined person, AND science-y person (used to be a big fan of biology and chemistry. really just school in general. that changed…….)
Betty Edwards, author of Drawing On The Right Side Of The Brain, was heavily invested in this theory, but her methods clearly worked. What I don't understand is why, if the underlying premise is incorrect.
Sooo what about dyslexic people? I've heard that we process language in the right hemisphere as a compensation technique that doesn't work that well, hence it being a learning disability. Is that true?
I don't know, all I know is that our brains are "wired" differently.
This video really helped me with my Corpus Callosum portfolio in psychology
There is a 19 year old girl named Cameron Mott who is actually left brained, but that’s because she got a hemispherectomy (removal of one side of the brain) when she was 3.
"I am using 100% of my brain"
- a person with epilepsy
My sister got her brain split up because of her bad epilepsy, this is making me question a lot about her behaviour. I'll definitely have to do more research about the effects of the surgery like wtf???
I think that these strange occurrences happen when the two sides are isolated in an experiment. For the most part both sides are receiving the same information and make similar judgments.
Glad you Mentioned the 10% Brain thing, But you should do a whole video debunking it!
Yeah, there's no way I use that much of my brain.
That'd be beating a dead horse, frankly. There are more debunks than there are people spreading the myth, at this point.
I know I am really late to this video, but would love to see a similar discussion of "learning styles" "multiple intelligences" and other similar "poorly explained in Psych 101 class" topics :)
Listened to skeptics with a K podcast the other day and they had a psychologist/ past life regression therapist. She was using the whole left/right brain dynamic in her explanations. She also explained that if evidence came out disproving past lives, she wouldn't stop because she's been doing it for so long.
I wonder if she considers astrology as another part of astronomy or cosmology?
I have always rationalized the 10% thing as that much at that split second. Sort of to reduce heat generated by the firing neurons, most of us never needs all 100% in the on position at once but in states of on and off.
But that is only my own rationalization from watching the fMRI images.
Pretty sure that's the fact that it got misinterpreted from. 10% of the brain at any moment got turned into 10% of the brain at all at some point and noone corrected it.
@@Winasaurus Thank you for understanding what I'm talking about.
Thank you. I believed I was ""left brained"" because of my autism, which was troublesome due to the fact that I enjoy creating music, which is allegedly a ""right brained"" activity.
Many people in STEM are also artistic! (Have you seen Prof Dave's band & music channels btw? 😁)
The fact that my high school science teacher showed us Bo Burnham's "Left Brain, Right Brain" as part of the lesson still haunts me
I am the left brain, I am the left brain
I'm so disappointed in Bo. Why did he have to contribute to idiotic pop psychology?!
Great video, but I really want to find more information regarding the two hemispheres. When the communication between the two is severed, it shows the presence of another self within ourselves. I want to find research regarding how to communicate with the non-verbal half without being split-brain. I want to explore the idea of getting the halves to work better together, more harmoniously, because I feel like this is an interesting line of thought to pursue. I understand without being split-brain they already have the ability to communicate with each other, but still hold separate beliefs and have different opinions, which I genuinely want to understand in a non-split-brain.
there's a bit more information in my biopsychology playlist!
@@ProfessorDaveExplains Thank you for the reply! I was not expecting the creator to respond to a comment on an old video! Thank you! Lots of Luv
@@Mossenfresh prof Dave is one of the best RUclips educators out there my other fav is Anton Petrov
Whenever someone throws out the “we only use 10% of our brains” statistic, my favorite retort is “So you genuinely think if you were shot in the head, there’s a 9/10 chance you’d be perfectly fine?”
Imagine only having half of your brain be developed.
I am not just creative and artistic, I'm also analytical and mathematical.
Would love to see a video on the 10% fallacy.
In short, it's misquoted from research that generalized as "You only use 10% of your brain /at any one time/.", the last part is what many people do not include, and as such think 90% of the brain is functionless.
In reality, because the brain is largely compartmentalized, you only use a fraction of it at any time. Reading, writing, motor functions, lying, remembering, all use different parts of the brain, or more or less intense concentration. So sure at any one time you might only use 10%, basic motor functions and light thought while jogging for instance, but the other 90% isn't a waste, it's there for other things, after all.
It's like saying you only use 10% of your car. Sure, maybe I'm only actively "using" the steering wheel and the seat and the pedals, but the windshield is helping visibility, the engine is helping with movement, the wheels are helping with traction, even though you're only "using" a tiny portion at the time, it all gets used eventually.
i loved this video so much. i never believed we were one-sided, and espcially not that we use only 10% ofour brains (which is a common myth everywhere). thnak you guys
This is discrimination of my people. Single brain cells rise up!
Can almost feel my hemispheres turn on each time it changes from the left/right partition of Joel and Dave
This is a very, very good video tending to a younger audience! It is scientifically accurate, which is not a given for many of the videos I’ve reviewed. It is using simple language and is presented slowly, fitting well for younger children. One aspect of improvement, instead of using percentages (over 90%) I’d verbalize them as (the very vast majority of) etc. to simplify even more! Thank you so much!!
None of my content is for children.
Professor Dave Explains Maybe not intended, but certainly appropriate.
Well, perhaps accessible to the inquisitive pre-teen. That I don't mind!
@@ProfessorDaveExplains i am. 9 years old.
This was an interesting and well made video to watch, the only thing I felt missing is music in the background.
This is only partially correct. Iain McGilchrist lays out the functions of the hemispheres in a more technical explanation in his published work "The Master and His Emissary". He goes into depth about the difference between the hemispheres as one being the Master (the right hemisphere) and the other being the Emissary (the left hemisphere). The distinguishing factor has to do with operationalizing in which the right hemisphere is concerned with maintaining overall functionality whilst being "reserved", and the left hemisphere is concerned with actions or impulsivity. There is extensive tests with both side hemisphere stroke patients and it's quite fantastic to go through the discovery.
You’re right.
I’m smoothbrained.
That's such a right brained thing to say.
I figured, since I'm decent at both math and creativity.
There are some yoga excersizes that are predicated on the so-called right/left dichotomy. The idea of those excersizes is to balance the two
5:40 is there a video with more on that I always thought that was BS
You may be using both brains but I'm using no brain
I always took it as a figure of speech not that people thought it was literally the left side or the right side
I compose music with sheet music and in an "academic way" and I study physics and maths now...brain ambidextrous. :)
Me: *Is both creative and artstic and extremely analytical*
Teacher: What now
I always felt that this was bs but I never had any proof, thanks.
have you ever thought of doing a podcast
I have one! It's called Professor Dave Debates. Check it out!
Oh man my day just got so much better.
awesome!
How do we know that the right brain is sentient and not just following patterns that it has been trained to do and assuming the correct answers?
~Let's talk about brains baby, all through the night~
I guess the statement "you only use 10% of your brain" applies when your brain is in "idle" state, when you aren't thinking of something particular or aren't fully focused to something. Similar to how computer's CPU isn't going to be at 100% all the time
I always thought this idea was bullshit.
Another bullshit idea was "learning styles." The idea that there are "visual learners", "auditory learners", or "kinesthetic learners."
On the one hand, it might have been useful to break away from previous rigid ideologies about education, it probably was not best practice to replace one bad idea with another bad idea.
finding what works best for you, and the best approach.es to a problem for your brain is not a "bad" idea
Yes, I agree with you.
However the ideas of left brain / right brain or auditory, kinesthetic, visual learning styles was taught and believed to be useful and relevant in education and business and many other areas of life. But it's not real.
There aren't really categories; the more senses are involved when you learn something, the more information is retained per repetition.
Except most people respond to similar and varied learning styles that are appropriate for a given topic. That's why so many say they're visual learners - it's just that people crave actually seeing a demonstration of what is being taught rather than hearing about a nebulous concept. Also, people often use the "learning style" thing to excuse bad understanding, like people who want overly-simplified pictoral explanations that are easy to understand but misleading (at least as far as being taken for a full explanation) or people who can follow instructions but lack an actual, deeper understanding of what they're doing.
Ill support any effort to stop movies like Lucy and Limitless
I only started hearing about "brain sidedness" recently, and still knew it was obviously fake lol
The whole left brain right brain thing falls apart when you realize being good at math/logic and art are not mutually exclusive.
Some of us are just middle-brained.
Right brain? Left brain? No thank you I have no brain
For anyone interested in a very interesting, albeit intensely dense, book on the intricacies of brain lateralization "The Master and His Emassary" is a good read. I found it to be very enlightening and gave me a lot to think on.
(Edit: minor grammar)
Maybe in the future we could wire up the right side of the brain to a speech box of some kind, so we could have someone with a surgically split brain able to communicate to us through both sides of their brain after the split.
WHEN YOU SAID HOGWARTS YOU GOT MY ATENTION SO FAST
Once a guy giving a speech at my school prize giving he talked about it. And he just listed symptoms of adhd. Qnd i felt so bad about myself because he made "right brained" people seem stupid. And being stupid all this time even when my teachers praised me for being smarter than most of my peers. That they were wrong. And all the things I believed about myself were true. Stupid, pathetic, emotional, childish. It made me almost burst into tears :']
Ah finally. The two have become one.
You see, I am only using 10% of my limited power.
Very good info but I remember hearing that this idea might be older than the fifties (though it might have evolved and become a way more prevalent idea by then) and originated around the time when Broca and Wernicke had originally published their famous research on the Broca and Wernicke areas. _The Strange Case of Dr. Jekyl and Mr. Hyde_ is said to have been inspired by this myth and of course, it's publication predates the 1950s (it was published in 1886).
"No you arent left brained or right brained, you just have a regular personality like the rest of us"
-Babylonian text
Makes sense everyone would use both sides of the brain roughly equally, underutilising one half of it would be a big waste of some heavy duty tech.
What about people that are creative and analytical?
Always felt like this was one of those things everyone talks about like it’s fact but never felt like actual fact to me. I’m very mathematical but also creative so the typical definition of “right and left” brain people just didn’t feel believable to me
I'm autistic.
I have an actual ASD diagnosis.
So my brain is affected in different ways.
My internal hippocampus filter is less efficient for one thing as others. Which makes me more sensitive, especially sound and smell. It's a sensitivity (read suffering) others cannot comprehend even if they believe they do. You don't have to live with my brain, do you? Everybody is sensitive to one degree or another, but definitely not on the autistic degree.
And my dopamine transmission is as lost as an ex meth addicts one.
I do have a sense of empathy, I'm vegan. But I hate dogs. (Hated them before I was vegan already though, just hated them even more after realizing the hypocrisy, irrationality, dangers and the environmental impact.)
Although hating dogs is more of a good thing. At least it's a justified one.
I'm also keen to rationality rather then indoctrination, religion, ideologies, following the mass and superstition. Very sceptic, sometimes a bit too much where I highly mistrust others. (although usually with people who have misused my trust in the past or tell plain bs in my face)
I also play shakuhachi for example, you don't play shakuhachi if all you do is follow the latest hype. You'll only play it if you're authentic enough to not care too much about blindly following the crowd.
Wait, what were we talking about?
Right, aRTistic brains myth.
You're "middle' brained. :))
@@nebtheweb8885 No, he's 100% brains.
I first learned about the split brain thing from Sam Harris in one of his books... I like to freak people out by telling them all this... And adding at the end "ya know... A person can live and function with only the left hemisphere of the brain... If the right side can have opinions and is a separate consciousness... And objects to being removed... But you remove it anyway... Is that murder?"... And watch em squirm... Lol
So which side of the brain is going to heaven? Lol, people most likely attribute their soul to the left side
I know I'm late to the party but great video Dave! Jewel you were amazing! I have a question about the whole one side of the brain controls the other side of the body, is it any different when someone is cross-dominant? They don't have one dominant hand or side, it's dependent on the task at hand (pun intended) and which hand or side was used to learn the skill first, for instance I write with my left hand, I use silverware with my left hand, I throw with my right hand, I swing a baseball bat right-handed, but after learning I was cross-dominant I taught myself how to weld with both hands, I didn't figure this out until I was about 25 after wondering for years why my dominant left writing hand wasn't my strong arm, it does seem that my left side deals with skills focused on dexterity and balance where as my right side deals with tasks that involve strength and large motions, would love to know what you think about this if you ever read this, thanks Dave! Have a good day, keep up the great work but don't forget to take time for yourself when you need it 😄
Just because we use each side of the brain equally doesn't mean that each side is as proficient as the other. I can think of a wire that's twisting from point A to point B. I can also think of a wire that is going directly from point A to point B without any twisting. Just because both wires start and end at the same point it doesn't mean that they are the same. One is clearly more efficient than the other. I could see how something like this could be similar to the brain where one side might be better at certain things than the other side is good at the things it can do. There's obviously people who are better at math than they are at painting. There's obviously people who are better at painting than they are at math. Just because the brain is used equally doesn't mean that the brain is equally talented. Then again this is just speculation based on what I heard from this video.
I literally took tests only to find out I'm neither right brained not left brained😂The same thing happened when I was a kid and now. I was in the middle. I'm good at drawing and is a creative type of person but I'm also equally interested in Science, logics and all
I prefer the Eyeshield 21 personality test.

this was an awesome video! Thank you!
You might not be left-brained or right-brained, but you're definitely scatter-brained.
I KNEW IT... I am sooo good at logic and reasoning, but am still categoried under right brained
It is obvious that the suggestion a person is either left or right when it comes to brain function is not to be believed.
That being said, my behaviour, interests and skills convince me that my right hemisphere is exercised more than the left.
I justify this belief by the recognition that most of the functions of the left brain I avoid as much as is possible.
An example would be speech and language, sure I can read and speak but do I?
Not if I can avoid it.
As a consequence how proficient to you think I am at these tasks?
If you run down the list of the things credited to the left hemisphere, they are neglected by me automatically.
This belief my not be upheld by an expert in the field of brain behaviour but I am very comfortable and inspired when lost out there pondering the possibilities of anything that my minds eye focuses on and extremely uncomfortable within when I call upon myself to engage in tasks such as this.
The lack of skill must be evident but that’s my point.
If you exercise one hemisphere and neglect the other I would conclude that the side that automatically draws you is your dominant side.
Holy crap - are these brain severing operations still done? No right? Sounds like torture...
it hasn't been banned, anyhow
having multiple seizures a day would also be pretty bad, but risk assessment looks different for everyone
@@river_brook Thanks!
Im not left brained or right brained, im brain-dead
spooky, I just read a book that talked about this and now I'm getting a video about it
man i couldn't live split brained. their sewerslide rates must be insane. its really fascinating but also depressing seeing as you could easily ruin someone's life by doing this procedure. i hope that there are better treatments for seizures and this operation deemed inhumane.
It's only done in absolutely extreme conditions where the seizures are constant and make life unbearable.
@@ProfessorDaveExplains ok i googled it and found that thankfully there are medicines that have (for the most part) deemed split brained surgery obsolete.
