Neurologists Debunk 11 Brain Myths | Debunked | Science Insider - วิทยาศาสตร์และเทคโนโลยี
The most surprising thing to me is how many of these myths originated back in the 1800s! Why are they still being spread today?!?!? It’s remarkable how out of touch we can be and how easily it can happen.
Gravity was discovered in 1600s. Just because something is old it doesn't mean it's junk.
@@dionium5462 gravity is not a myth though. You missed the point.
@@adamadam367 before newton proved that gravity is real it was considered as a myth. The Greeks created the concept of gravity and levity, and no one thought of it as real aside from ancient Greeks until newton has proven it to be real.
that's because there isn't anything better to replace it... such as the IQ test, it's still the best predictor for future financial success and longer life
Mostly because at the time it was being used to explain why White Europeans were 'superior' to other peoples.
My wonderful mom has always said that “everyone is smart in their own way,” as Dr. Kamitaki also so empathetically expressed, and in my 43 years of life I’ve seen this to be *so true*! There are so many ways in which a person can be talented and brilliant if we just look for it and appreciate it!
Yes! I've been an advocate of this perspective for as long as I've understood it, and the evidence is everywhere. We are remarkably resilient. Just look at the amazing things people with "disabilities" can do, or how the brain adapts when a part of it is damaged!

The IQ one has always bothered me. I am a "gifted" person with ADHD. While I ranked above average in IQ tests, I struggle to function because simple tasks like doing laundry and remembering appointments are incredibly daunting. It's like whoever chose my stats had a really fucked up sense of priorities
Same here x-x And then there's the "If they would only apply themselves more since they're so bright" and all that stuff. I mean, yeah. Like Dr. Barkley said, though; we know what to do, but can't do what we know D: That pretty much nails it for me, usually.
Man, now you've got me curious. A few months ago I I tried getting tested for ADHD and the phsicologicst argued in the results that it was negative since wasn't possible because I had an IQ above average

I want everybody to know that as soon as the left versus right brain myth was debunked in this video I got an ad for Twix, saying it doesn’t matter if it’s the left or right.
I was PROFOUNDLY confused bc I was merely listening to this, so I didn’t see that it had changed. It was a supremely jarring experience. Kinda terrifying, actually.
That’s beautiful!
I got the same ad at exactly the same time as you!
Hmm thats funny i got no ads?

Mine showed up earlier, far before the right left brain, yours just too meta.
I didn’t get a Twix commercial but now I want one just so I know what y’all are talking about.

Thanks for debunking the myth about male/logical female/emotional myth. I'm a woman and I can think pretty rationally when I need to. The only thing I become emotional over is cats, but it's a luxury I allow myself.

So true, I'm a woman n I'm less emotional than normal people (at first I didn't realize it but then many people told me, so..). My husband even more emotional than me. Haha. Be
I’ve been an RN for almost 30yrs & the stuff I learn about brains has changed so much since I was new. We’ve learned SO much but still some things we just shrug & say “i don’t know. Brains are weird.”
Also, does being ambidextrous change how one’s brain reacts? (As opposed to be left or right-handed?) just curious.
As an ambi', myself, I'm gonna have to say there's going to be a lot of "It depends" for that question...
I was born "left handed" and ended up LEARNING ambidexterity to get through life easier. My mother (God bless her) was a staunch supporter of the idea of "Never tell that boy he can't do something that way." SO the teachers at school got backed off when I picked up the right handed scissors (or the left handed ones) or any other utensils simply because they were in better shape and more available than the ones for my "handedness"...
Part of the "trouble" with ambi' is that I lose some of the sense of "right and left" orientation, because there's less influence on the cues for it. I had to just memorize it, where the "normal" person bases it on which hand they write with... AND the other direction is just the opposite... BUT I didn't get so much of that. Sometimes I write with one hand, but when it gets tired or I just don't feel it, I'm working with the other one... haha...
The "advantage", however, is that I'm not so limited. Having learned to do things with both hands, relatively equally well, while it's taken me just a little longer to develop that "hand-eye coordination", now that I've got it, I'm generally more intimately involved in any skills with my hands... Being able to carry on a task when one hand gets tired, simply changing the duties assigned to the hands, DOES give me more "range" or "endurance" for it, and that adds to productivity... AND if I injure a hand, well, the other has less trouble taking up the slack, so to speak. I'm just a little bit less inconvenienced... and you might be surprised at how aggravating life can get when the hand you USUALLY wipe your butt with doesn't work well enough to do the job. (lolz)
Someone who was just naturally ambidextrous might have developed their "hand-eye coordination" faster than me and not suffered nearly the disadvantages of putting up with dull scissors or trying to negotiate Caligraphy with the screwed-up "bent" pens... Switch-hitters in baseball tend to be prized by teams, making that bar of performance just a little lower than maybe the rest of the players, whether orthodox or "south paw".
AND A LOT of it's going to depend on the culture they were raised in, and their parents and general "support" for it. Some cultures still stigmatize left-handedness as "of the devil" so there can be dubious mistrust and outright abusive tendencies for such a little detail. That can stunt the skills with the left hand, and diminish their appreciation of a talent... just as much as quietly practicing on its own can be a great benefit, building the neural pathways and creating more dynamic flexibility in a person's dexterity overall.
IN ANY CASE, I hope this helps a little bit. I'm no pro' about neurology, of course... JUST a perspective that might offer even some subjective information about how life is experienced, and the evidence (as I have anyways) that suggests there most certainly IS some difference in brain development between right handed or left handed folks and ambidextrous folks.
I DO still have a dominant eye (my right one)... BUT just about everyone has one side of their binary systems (the organs and nerve nets in pairs) that's got a little shorter pathway to the brain and a little faster impulse travel, a little more dominantly reliable than the other... That's probably normal even for the most ambidextrous among us. ;o)
@@gnarthdarkanen7464 I appreciate the way you organized your comment.

Good grammar/writing skills are hard to come by these days, especially on TH-cam.
So I had to point it out, and hope that those skills might rub off on me and the rest of us here in the trenches of the comment section.

IQ is kinda like horsepower. Even if you have high horsepower, if you have poor grip, down force, high weight, poor aerodynamic, your car is still gonna be slow as hell😂
IQ is not fixed though, continuous education can increase a person's IQ
It's silly to want to believe that a kid after pre-school taking an IQ test would score the same if they take it after college.
Especially looking at the IQ tests which use specific formula that you can sorta train to discover, but also, you can generally train your brain to take tests better by taking tests over and over again.
Pretty sh## argument. iQ is not horsepower. You dont go around killing people like a car running over people. If you have High IQ just because u lack grip, down force etc etc. Usually IQ stands to denote how fast you understand certain things if not most things, a HIGH IQ individual is less prone to anxiety, erratic behavior and understand what most people don't around him if 100 people have 100 IQ and 1 individual comes with 120, he will certainly have higher Odds of becoming their leader if these 100 men have 120 IQ then a men with an IQ of 140 would be able to stand out. Its always ALWAYS gonna be a factor of genetic mutation as well as environment factors. People who strive to do something else and unique entirely will have higher probability to have high or better IQ then rest of the people/most of the people.
From what I’ve read, most parts of the brains do not make new brain cells, but neurogenesis does occur in the hippocampus and glial cells are possibly able to thicken or regrow as well.
Just wondered about that since I often heard that it’s a myth that we only have a finite number of brain cells after we become adults.
They stated that myth at the very end of the video.
Was wondering about the same thing
Neurogenesis in adulthood has been observed in 2 regions of the brain ( the Dentate Gyrus in the Hippocampus and the Sub Ventricular Zone of the lateral ventricles) in mice. In humans, it has been proven only in the Dentate Gyrus and the investigations regarding Neurogenesis in the lateral ventricles are still ongoing.
Therefore, we don't have a finite number of neurons. However, Neurogenesis in the above mentioned regions does slow down as we grow older.

Ok so on the subject of IQ tests, I have an 11 year old son with global developmental delays, he can't read or write yet, but boy, he can tell you about a LOT of things, and in great detail! Unfortunately this world is based on paper and ink, so to speak, so people like my son are considered intellectually disabled, but that's just not true, my son is very intelligent, so who cares if he can't write it down or read it? There's videos on literally everything these days, and literally everyone has different ways of learning and communicating, so why are we still measuring a person's intelligence by literacy alone? It doesn't make sense.
I was diagnosed with a linguistical disability, and now I'm an amateur writer. Things of life
I agree! We can't judge people just because their head is smaller/bigger or if they play basketball then it would depend on their height. Nah skills matter, it's the development. If you're not good at one then you're good at another. I actually think people who have disabilities like adhd or autistic could be great at certain other things than normal people.
@@exp-io853 oh yes, people on the autism spectrum, I know because myself and all 3 of my children are on it, are highly intelligent, my middle child has ADHD, and is extremely intelligent, but just isn't capable of focusing for long enough, especially on subjects that bore them to death! We're so incredibly grateful that their school has based their ILP on their interests, such as anime and manga, because otherwise they'd literally have no chance in hell of passing school! As it is, they will spend hours doing English and Art, but Math... they're so good at it that it's boring, it's not challenging at all, they absolutely hate it, but they need it to pass!
I recently read somewhere that a lot of CEOs/Higher level executives are dyslexic ( I'm not presuming your son is dyslexic by any means) because dyslexic persons tend to have good verbal communication, delegating and social skills, and excellent memory. Goes on to prove that there is many different ways of being "intelligent" and being not so good at certain things traditionally associated with higher intelligence doesn't mean anything any more. With sufficient technical and emotional support, learning "disabilities" should not affect the quality of life and opportunities.
I love your mindset and perception your son will become a good human rather than a highly educated inteligent rat like this shitty world asking for. Save him and make him a good human. 💙
This is probably the first "debunked" where i have known and believed half of the myths. I am mind-blown
Which ones?
Lol same
This was woke bllsht. IQ tests are the best thing and these people are 'debunking' it. Clowns. Anyone who parades social intelligence or emotional intelligence is a hack
That's because other equally qualified psychologists or neurologists can give you the opposite opinion. They look and read the same papers but come to different conclusions.
This video is false. IQ predicts outcome, and is the greatest predictor of outcome at 40% correlation.
I did the high school test without food and drinks after a military exercise where we didn't get to sleep a lot. Without preparation, once. Definitely noticed a difference. Everyone is dumb as a rock if they are tired enough.
If you miss enough sleep, you can become drunk, effectively speaking.
@@ewdtrey Yeah, then eventually on drugs, as you start hallucinating as your brain tries to access dream sleep while you are conscious. Or so I've heard.
I’ll never tire of saying how fascinating this theme is. Just love it. 🧠❤️
Lol, the size of the brain myth has always made me chuckle. Saying someone/thing is smarter because of a larger brain, is like saying a giraffe would be better at basketball than a primate, because it is taller. 😏
Good example
We're comparing same specie. That's not a good analogy. Tell me that height difference between a short and tall guy doesn't matter.
@@shadmansudipto7287 U r right too
@@shadmansudipto7287 in the video, they compare brain sizes in different species (chimpanzees are used as one example).
And in ours, height helps in basketball, but skill will beat it. Just like any other attribute, the key is development.
@@rolmodel12. my point is, there is not enough research to say that brain size doesn't matter. The people in this video speak too confidently expecting us to not fact check unlike the people from the other videos of this kind.
This is one of the best episode of these expert debunk videos. 😊
Yes. Please bring these guys back.
Pretty rich that neurologists are speaking about psychology topics as if they are experts. I understand that to the layman it may seem as though they should know a lot about psychology, and therefore IQ, but these are really two very different fields. Neurology is all about the physiology of the brain. While physiology can certainly affect cognition, neurologists aren't the ones measuring that. If a neurologist's patient is having cognitive issues, they may image the brain and run various tests to look for abnormalities, but how do they measure any potential cognitive deficits? That's right. They refer them to a psychologist to take an IQ test. This really turned me off from this channel as a whole. It's a real problem when experts pretend to be an authority on things they're not because the general public will just eat it up without question. I probably learned more about IQ in my one semester of cognitive science in undergrad than these guys did throughout their entire academic career. It just isn't a focal point of neurology.
Also, brain size does matter. It's just not the most important factor by a long shot, but it does likely matter. It's just that other things that make up the structure of the brain are believed to contribute much more to our intelligence such as cortical thickness. Brain size has a positive correlation (though admittedly weak) of 0.3-0.4 out of a possible 1 to intellectual capability. Having a larger brain than Steve doesn't mean you are smarter than Steve, but if your brain is significantly larger or smaller then it might be a good indicator of something. You just can't compare size when making interspecies comparisons due to the aforementioned structural features of the brain that we now believe contribute the most to our intelligence.
What's even more hilarious about this video is her example of the bear. Bears have significantly smaller brains than humans. It's not just the size of the animal that determines the size of the brain like she tries to claim. Many large animals have very tiny brains proportional to their body mass and this data is easily found in a google search. Embarrassing! Humans have one of the highest brain to body mass proportions. I seriously doubt it's mere coincidence that the animals in which we've observed the most intelligence behaviors also seem to share this high ratio of brain to body mass (dolphins, whales, elephants).
I would hate to have this lady as my neurologist. Did she even pay attention in class? What is even going on here?
Except that they are wrong on brain size, IQ and sexual dimorphism.

the videogame thing is so true. There's obviously trash in all entertainment and videogames are no exception, some really do feel like they're slowly strangling each of my neurons, but I've found that games like Snowrunner really make you think logically and do a lot of risk vs reward calculation, throwing in variables like your vehicle's capability or potential obstacles on the road. Same as sim or sim-adjacent racing videogames, you have to be aware of your own capability as a driver, your car's capability, your tyre wear, changing weather if it's a feature, strategy, other drivers...Videogames really do give you hand on experience to form connections regarding quick decision making, strategy and risk vs reward thinking that a book, a school lesson or a documentary can't teach you, specially for younger kids that can't get into IRL situations that build those connections.
IQ tests measure a number of different mechanisms for your intelligence, and even the primary determination of how fast someone can spot and process patterns is very valuable data, not to mention IQ is highly correlated with many outcomes in life. Just because we found some more nuances to define doesn’t mean we need to throw it out completely.
School staff made a big enough deal about my measured 1Q that my parents made big changes in my life. I realize the doctors put IQ test numbers in the appropriate place because people can have many skills and abilities those tests don’t measure. For me, however, my childhood and the peaks of my life have been highlighted my verbal ability and executive functioning. Lives can be significantly influenced by the experiences and opportunities given to a child. If you are young, try all the good things. You might find an extraordinary version of yourself no one yet sees.
One thing I've always wondered is, since our eyes are at the front of our heads - as it is in most species with eyes - why is the sight processing part of our brain located at the back? You'd think it would be at the front closer to the eyes. Also, how did the whole left side controls right side of body and vice versa come about? That seems like a very strange layout too.
I also thought about this strange positioning of visual cortex when they mentioned it in the video.
The answer lies probably in how the parts of brain evolved over the course of primate origin.
Optic nerve as it traverses the brain has projections into the temporal and parietal lobe which also processes the optic signal and final image is formed in the occipital cortex.
About the contra lateral control, it's because many nerves crosses to the other side either in the brain stem or the spinal cord.
It's most likely because of something called somatic twist that occurred in vertebrates during the course of evolution. Invertebrates don't show this anatomy.
I think because of the complexity and the success of life on Earth, people gain the idea that all life is optimised and designed almost perfectly but there are a lot of flaws and pointless waste of resources. A few examples of these unintelligent designs: giraffe’s laryngeal nerve is much longer than it needs to be, human hips and birthing canal are narrow causing birthing to be dangerous and painful and tasmanian devils’ have 4 nipples yet have a litter as large as 30 resulting in very few surviving. These are just a few examples but every species has at least a few flaws in their design.
My point was that there isn’t a good reason for it, its something that didn’t create a big enough disadvantage during our development as a species to evolve
@@kripa2982 also the optic nerves pass and cross (optic chiasma) in the thalamus and above the hypothalamus where it transmits information about the light conditions. With that information the hypophysis can regulate the circadian rhythm via the release of serotonin or melatonin hormones
@@kripa2982 and in the thalamus visual information is treated in the lateral geniculate nucleus before being sent to the occipital lobe

Did a neurologist just say that chimpanzees are just as smart as humans?
If it's a well-established fact by Science (TM), then the US needs some new category in their affirmative action quotas...
Well they are as smart as human children maybe that’s what they meant but they said it vaguely
Yeah, this was strange
yes? humans go through different intelligence quotients throughout life. so saying that a chimpanzee is as smart as a human (albeit a child) is a factual statement
Also mention pattern perception. Some of it happens before the neural signals even get to the brain. Interesting. Very interesting video. Thank you.
I love the violent paper ripping ! 😂
7:00 one key thing about memory problems they forgot to mention is how certain chemicals can cause them. Household paint without ventilation, spray paint or stroke paint either way, is highly toxic. Same thing with glue, solvents, degreasers. You can use these chemicals just make sure to do so with ventilation and protection.
1:01 She said that Chimpanzees are probably as smart as we are. She is supposed to be a neurologist.
Maybe as smart as she is lol

I love when TH-cam comments think they re more knowledgable than the people who literally do this as a job and studied it for years💀
First of all I have two things to state:
1.Amazing video, i have definitely learnt a lot
2.I am having a doubt depending on the part where the dominant hand indicates the kind of person you are. So what if you wrote with both hands since your childhood or learnt to write with the non dominant hand later in life
A tendency is not a solid rule and doesn't determine things. There was a correlation found between brain activity and hand dominance. As they stated, none of this determines what kind of person you are.
@@KxNOxUTA Thank you
IQ presupposes that the best way to measure intelligence is by testing an individuals pattern recognition aptitude because it is the closest synthetic analog for learning problem solving skills. That makes IQ scores an excellent predictor for aptitude in STEM fields and technical employment. However it is not an effective predictor of aptitude for creative or interpersonal skills, which are equally as important for personal success in life.
Thank you for this video. All of those myths have been taught to me during high school. And the high school teachers were so sure that their curriculum and lessons were factual because they were taught the same from the previous generation.
Excellent insights about strokes - thanks. Especially the one about where strokes can happen at any age.

When I was 13 I was diagnosed with Asperger's. This was in '08, before they redid the ASD to the 3 levels they are now. I scored a 145 on the IQ test I was given at that time. It was not until 12 years later when I was 25 that I found out I have Aphantasia. MOST people with Aphantasia have no idea they have it. I just thought that when people were saying to "imagine" they were only using a method like an analogy or metaphor, not that they LITERALY meant to picture something. I think this makes the test I took very flawed. I can remember there being a good portion involving mental assembly of shapes into a final form. I don't think Aphantasia has influenced my logical or academic intelligence, but my social instead. I have a really hard time relating to people. Empathy and sympathy are not in my head a bit. It's hard for me to relate my own experiences with others, since my recall is mostly like reading a script. Things just exist as a list of details in my brain, but obviously not a visual. I have inner voice. Some info I just know and don't try to recall, it just happens. I am also completely ambidextrous. I will grab a writing utensil and use it with whatever hand is closer to it, without thinking about it, and make the same poor quality penmanship.
Great video, but is "you can't prevent a stroke" really an existing myth that's out there that people believe??
Yes.
There’s myths.. and there’s rumors.. the question about “can’t prevent a stroke” is definitely not a “widely held belief or idea”, which is the definition of a myth.
I mean you can not reduce the risk to 0%, but you can reduce it.
Also, "you can't prevent a stroke" is a somewhat different postulation than "you can't reduce the risk of stroke", which is the one they addressed.
Fascinating, I have always said IQ tests education not intelligence & I was right, I scored a very high score on the IQ test but in the midst of it I realized this is not testing my intelligence at all, because if I could not read I could not take the test, being able to read does not test instinctual intelligence, because you have to be taught to read no one is born knowing how to read.
You have never taken a real IQ test
Saying that makes me think you're indeed bright
@Rick Vis some learning disabilities exist and some kids learn differently doesn't mean they've got a lower IQ and I've seen some kids who had a lot of trouble learning in elementary school but as they grew older their acedamic performances became average.
@@TheYankee006 I think I replied to the wrong person lol
That is asinine.
If you are able to take the test it tests intelligence. IQ tests measure problem solving skills and education plays a miniscule part of it. That is why a highly educated person can score worse than an uneducated person

We use "only 10% of our brain" at a time the same way that we use "only 33% of our traffic lights" at a time.
Yeah. The synapses in the region of the brain relevant to whatever task your performing will light up, and that will account for a small fraction of the total synapses that can be used. This is the basis for a very cool form of brain surgery, wherein neurosurgeons will map your brain activity in real time to see which areas of the brain 'light up' when you do various tasks, so they figure out where your most important neural pathways are, and if they have been disrupted or damaged during surgery.
That's false. Most activities require us to use far more than just 10% of the brain.

Using 100% of your brain would mean you are having a giga-seizure/stroke I guess?

Small comment on withdrawal from social interaction using videogames, this is usually a symptom of an underlying psychological issue such as depression, social isolation (e.g. due to bullying) or lack of stimulus for someone with high intelligence. This does give a feedback loop because it causes further lack of development of social skills, but is hardly ever the initial trigger

“Chimps are just as intelligent as humans”…
I can't see how that could be the case without some kind of definition of "intelligence" that would have to be designed for it to be true, somehow, and yet it's hard to imagine what it could be to be minimally valid. The best I could come up with is that perhaps by some neural correlates of intelligence, chimps' neurons are just as good, or some intelligence-related tasks. Chimps were actually found to have a significantly better working-memory than humans, and that's key for human intelligence (or highly correlated to IQ), but that's obviously not enough for human-like intelligence.
I think maybe the myth about different sexes having different brains probably comes about because of the difference in hormones and the testosterone. For instance, lots of testosterone in males may cause many things; one being greater risk taking - whether that be success in the business world, or be the choices that made the man sitting inside a prison cell.
The brain itself would be the same from an observation standpoint, but so much more would be going on behind the scenes.
IQ as a standalone is a measure of person's ability to identify and discern patterns - how fast, the complexity of patterns, e.g. from simple "find a missing picture of four" to identifying unmentioned amount of patterns in a set of many. Visual, verbal, sequential, and, most importantly, "existing". The last one is the difference between a functional and devoid-of-reality brain. "Social Intelligence" and "Emotional Intelligence" are pretty flexible and can be learned/improved with repetion and, again pattern recognition. I mean, psychopats apply just that. There is no imitate "abstract" and "logical" thinking. You either see it or not. Asperger, as an exception - it draws a cleaner line between the two.
I really like the way he talk, i wish I'm taking his class if he's teaching
2:18 I thought Iq tests were used to find the Geniuses yet it was used for another cause. I really think that's so cool and helpful for people. Wow I did not know that.
Is is a politically touchy topic. R@ce differences etc.
What about people that are ambidextrous? I do write with my right hand, but I can write with my left hand as well and there is very little difference between the two.
I write in cursive also. I'm a licensed cosmetologist and there are a few hair cuts that I use left handed shears and others I use my right handed shears. I was a switch hitter when I played softball, the glove was on my left hand and I throw with my right.
I play ping pong left handed.

The one about the eating fish getting you smarter I think is related to the phosphorus.
At least that's what I've been told as a kid - that the phosphorus in fish helps make you smarter.
I have no idea if there's any truth to it though.
So how everything works in the brain except the general areas depends of everything about the individual health, personality and post experiences.
Maybe we all are the individual formed by the acumulated experiences in our life. Experienced with the brain we were born with and interpred with culture, way of life and so much more.
It feels like research of the brain (and nore fields) to get an answer also opens 10 more questions.
The more we know, the more we also know that we dont know.
Its so cool and you people are Awesome standind at the frontier of science. People like you should be presidents and world leaders.
Awesome video, thanks! =)
I agree with everything in this video, but there IS at least one example of sexual dimorphism in the brain. There is a nucleus (a group of neuronal cell bodies) called the Sexually Dimorphic Nucleus of the Preoptic Area that is significantly different in volume and shape between males and females. But yes, through the naked eye, you couldn't really tell the difference. Awesome video!
Yes that’s the only difference. They have already spoken about brain size tho. Males tend to be bigger thus their brains are bigger.
I was just going to comment that as well. I don't like that she disregarded it because this discovery has real implications in science and is very important to the transgender community, since it has been confirmed that the only case known where people which were assigned male at birth have a female proportion in this area is in transgender women, and vice versa for transgender men.
There are also several functional and metabolic differences between opposite gender brains which cannot be seen with the naked eye, but can be observed through biochemical methods and functional magnetic resonance imaging. For example the ways that the brain lights up in different patterns when presented different stimulus. The differences aren't huge, but they're noticeable.
Sex hormones also induce many epigenetic changes in all cells of the body including brain cells, especially during development since they are able to cross the blood brain barrier. There are many studies confirming that differences in sex hormones during prenatal development have effects on future behaviour. There are also statistical differences in the types of mental disorder prevalences among different genders. And there are several other examples. The short story is, these may not be noticeable structural or volumetric differences seen at a macroscopic level, but they sure are functional differences going on at the microscopic level which we are yet to fully understand. And it is important we do not disregard these as they have real life implications in scientific discoveries and the research of new drugs and tratments.
@@athenachavez8 yes! I didn't even think about all these other differences that exist between the genders! You know your stuff!
The fact about transgender people is incredibly important as it shows that it is clearly not a choice; gender identity has a genetic component, there are predispositions.
And the same goes for sexual orientation! One of the Interstitial Nuclei of the Anterior Hypothalamus is different in volume and shape between heterosexual and homosexual males.
Sex, gender, and orientation are all factors that have a clear correlation to differences in the anatomy and physiology of the brain.
@@athenachavez8 Important to transgender community does not mean accurate tho. There are minor differences that as you said can not be seen with a naked eye but that is only natural as male and female bodies are still different. I’m pretty sure what they’re are talking about is the myth that men are more logical or their brains work completely differently which is not true at all. Other than that the studies showing those minor differences are actually not conclusive and more research needs to be done. Other things you mentioned are specific to sex as a whole or not actually related to significant brain differences. What you said just confirms what they have already mentioned.
@@ale-bt3pd Thank you
And yes! that's another one also. Totally agree. And I hope more people see this thread. I feel like the lady of the video kind of hit a big blow on decades of research perhaps because of political ideology. I can see how her intention may have been to do good. But when it comes to science we have to be careful to not introduce politics or personal bias which can easily spiral out of control. There should be no room for controversy. Science is neutral and does not stand sides with anyone. It's only goal is the search of the absolute truth of how things work and nothing else 😌👌🏻☘️
9:40 As a kid, in the 60s,I was told to eat fish which contains a lot of phosphorus that is good for your brain. Actually many other foods contain relevant quantities of phosphorus like chiken, pork and organ meat (liver, heart).
The problem is that phosphorus is not important for brain alone, Phosphorus is needed for the growth, maintenance, and repair of all tissues and cells, and for the production of the genetic building blocks, DNA and RNA. Phosphorus is also needed to help balance and use other vitamins and minerals, including vitamin D, iodine, magnesium, and zinc.
To age better : New ongoing longterm studies in france show that ("altruistic, compassion type") mindfull meditation (comfortable) makes a huge difference for aging better (wile), better than for instance starting to learn a new language or vs. changing nothing.
Actual change in the brain begins actually also to become detectable after 2-3 years 'practice' (that, BTW, becomes à pleasant need).
Fascinating... Science is awlays changing... For instance... Some of these debunks will be dubunked soon and so on!!!

"we do know for a fact that chimpanzees are probably as smart as we are" 😐
Just a comment on the epilepsy part of this video; epilepsy isn't necessarily lifelong. I myself had Petit mal epilepsy from the age of 10 to 17 and haven't had a seizure since (now 27).
That’s awesome.
Yeah, same.
I had rolandic epilepsy as a kid, but grew out of it by the time I was ten. Which most kids with that condition do - it’s the most common type of benign childhood epilepsy. And I didn’t need daily meds either. Just had some in case I I had a seizure, which were thankfully very mild
Well, if we go by a pedantic definition, you're never truly "cured" of epilepsy, thus it is a diagnosis that will always be with you in your clinical history.
For practical purposes though, it is like you said, sometimes seizures diminish and eventually can stop altogether for an indefinite period of time, which something important to note because most of the patients I've interacted with seem to hold the notion that being epileptic means being sensitive and in danger of any potential "trigger" or "surprise attack" for the rest of your life, when that isn't necessarily true.
I was discussing the myth about the percentage of brain we use and this video came to my feed
A person's intelligence is measured by how they exercise the basic rational capacities: he who understands abstract concepts can form true and correct judgments and can reason out clearly.
…which are found on IQ tests.

Long time after ...upto the point and factual smart people discussion 👍👍👍👍👍
These 2 are neuroscientists yet gave such a diluted explanation of intelligence to please everyone on the spectrum. Intelligence is the brain’s ability to adapt. It’s measured using logic tests, for example, because it best correlates with this ability. Language ability too can give an indication of one’s intelligence, though it’s not a very good way of measuring it because literacy is so much tied to education. “Emotional intelligence” on the other hand is a completely different set of skills and I’m not even sure if it’s ever been fully defined. Is it a measure of empathy? of sympathy? of social understanding?
I think it’s important to make these distinctions and define concepts clearly to give people _more_ confidence. Because I believe confidence stems from understanding one’s strengths but also one’s weaknesses. But if you falsely believe, for example, that your intelligence is comparable to that of Einstein because you’re very sociable, you’ll easily get disappointed and annoyed when someone points out that you’re not.
Know your strengths and weaknesses instead of convincing yourself you’re intelligent by _some_ measure. Because that would just end up with you endlessly comparing yourself to others. Any set of skills can be seen as a strength, not just intelligence.
What about IQ consistently correlated statistically with success in careers? What's the explanation for this?
IQ is an outcome
LMAO no, success in careers is far more correlated with your family connections.
I keep telling people that Intelligence is a mix of IQ and knowledge and people keep saying Im wrong
This is the best video to send uncles and unties. Thank you!
Social and emotional intelligence are not really conscious ways of problem solving to me but more in the department of intuitive perception. Not really sure why we label it as intelligence and thus branding people lacking some of it as "unintelligent".
1000 % quality comment.
Yep. Thank you. The terms were absolutely made up because human beings have a tendency to be incredibly insecure about their intelligence and this gives them more potential outs to preserve their egos. I'm not saying the concepts are made up. But yes, intelligence is a misnomer here and contributes to soooo many of the infuriating and brain-rotting takes of the general public about IQ and intelligence.
Yea, EQ isn’t really a quantifiable metric and more of a way for people to cope
So we're all intelligent, but it lacks development and practice(?)
Im gonna wait for someone to debunk them for debunking what they debunked
so much nonsense in the diet side of their debunking
Please keep making videos like these!! very interesting !
It's so interesting to think of this as the brain studying itself
I really enjoyed both of you. So sophisticated and direct.
@@priapulida please elaborate!
I do believe some people are born intelligent and I do believe that some people develop intelligence through being naturally curious. I have proven this with me vs a few people in my family. I've even notice that people who lack a certain level of intelligence have child like tendencies. My sister, father, and a few of my cousins. Let's go back to being naturally curious and how it develops intelligence. I have notice that a person who displays a high level of curiosity as a child tend be good at a lot of things and they can use other subjects to explain things that they are not an expert in very well and get most of it right. Many people don't realize that their is a difference between being smart and intelligent. Smart has a lot to do with decision making while Intelligence deals with decision making, problem solving, and creativity. Not just because you are intelligent doesn't mean you are good at all three equally, but you still posses the quality to get all three done regardless. A person who get all A's is considered smart which goes back to decision making and memorizing. Society reveres them, but a person who is a mechanic is considered not as smart, but people do not realize that this person is intelligence because putting a machine together requires all three that I mentioned before. This is why I say books doesn't make you successful, but hands on experience makes you successful. The subconscious mind is quicker to absorb when you do.
Incredibly subjective post and ultimately meaningless because of it.
Just a huge cope
It lacks any substantial evidence and reasoning
I used to make these kind of argument in middle school with my friends..we all thought we developed some huge reasoning capability with intelligence while sounding like this
Thankfully realised and out of that phase
Is the Mediterranean diet really so good, or just good relative to the "standard American" diet?
When someone said you're stupid I'd highly recommend this video show them
Thank you, for this and my pet peeve is why are they still being told about told about the ten percent and so on 🤷🏼♀️ . I can agree my dad was smart in both books and street smarts. You mean if you think someone is following you and you do things just to make sure that they're not and they still following you you're schizophrenic. Okay you said your gut feeling is wrong.
Some are set in their ways and beliefs and refuse to think otherwise.

I’m wondering if all strokes can be prevented though.. I work in neuro-oncology and our patients with brain tumors are at an elevated risk for stroke. Im not sure if this is due to their medications or because of tumors themselves. I can’t speak to their cardiovascular health, but sometimes they will get strokes and are otherwise healthy people who aren’t overweight and don’t have a history of cardiovascular ailments. Hailey Bieber apparently had a stroke recently. I guess all of these people had unhealthy hearts? Idk. Really curious about this.
You can prevent strokes due to preventable causes (of course), but there’s always gonna be those freak incidents where a perfectly healthy person has one
I have a question I was on Abilfy and I couldn't remember a persons name and how nice he was and I hated that medicine and later I got off if but I know his face but not his name but my memory is solid on a lot of it but some I have to be reminded of it.

I have one last question if we use of our brain too much will it get better or will it kill itself slowly (degrades it's performance like our kidney does) ???
☝️☝️look up that handle, she ships swiftly,and she got shrooms,Dmt,Isd,modal,psilocybin,chocolate bars,she got a lot..🍄💊🔌…..
No, it won't degrade, it will definitely get better.
While bigger brain doesn't necessarily mean better, saying size is completely irrelevant is not 100% correct either. If two brains are equally complex, size could be potentially relevant. There's a reason why we have bigger brains than gorillas despite being smaller in body size.
In 2007, doctors found a guy in France that was functioning normally with 90% of his brain eroded away due to fluid buildup. IQ was a bit low at 75, but otherwise normal. His name was withheld in the article.
Can they tell what improves executive function and memory
Same goes for prodigies, thank you for the left and right handed people even now there's people still say left handed people are evil. I beg to differ my little brother is left handed and so is my sister in law his wife I know lucky. Isn't hereditary could play a part in a stroke my dad had a few of them mostly light one's.
There is some evidence that left-handers have higher rates of psychotic disorders like schizophrenia. Also, strokes run in my family, but my family were also sedentary, overweight, diabetic, and had very poor nutrition. My cousin had a major hemorrhage at 30 years old, but he only ate microwave pizza, didn't exercise, and lived an extremely stressful life. A lot of health issues are not genetic, but we often inherit bad lifestyle which is something in our control. Exercise, fish oil, magnesium, are all very good at improving the vasculature and reducing risk of stroke
@@EhurtAfy Agreed. And yikes, sorry to hear all that. Reminds me partially of my family and me :( But in our case, the bad lifestyle etc. is caused by ADHD/us being untreated for years.

"fish makes you smarter" comes from iodine deficiency. Seafood is a good source of iodine. Prior to iodized salt, people who did not eat a seafood based diet had iodine deficiency which causes a lower average IQ of about 15 points.
You can get the benefits of fish without the drawbacks (needless killing, mercury, microplastics, PCB's, biodiversity loss, contributing to the environmental damage caused by the fishing industry) by eating plant based foods with ALA Omega-3 like ground flax, chia, and walnuts, as well as by taking a DHA/EPA supplement made from algae.
Fish get their Omega-3 by eating algae, or smaller fish who do so.
Thank you for the information ❤
