Neurologists Debunk 11 Brain Myths | Debunked | Science Insider 

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.

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

She's still pretty I want her to be my doctor

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)

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.

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 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. 💙

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.

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.

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.

@@navneetkaushik2482 poor wording but to our know universe yeah probably

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

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.

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

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.

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 😌👌🏻☘️

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.

@@maxi1ification That is highly unlikely

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.

Psychometricians generally regard IQ tests as having high statistical reliability.

@@psychicspy Statistical reliability relies on normed data. When a child comes in and their testing shows high variability, that screws with the statistics. You take two children with a 120 IQ. One child is neurotypical and all of her subtest scores were within the normed stasticial variability. You can say that yes, the likelihood of this child's FSIQ being an accurate measure of their IQ is pretty high. Now take a twice exceptional child- gifted and disabled. This child also has an IQ of 120, but their subtest scores are extremely varied. Their lowest score was 91, and their highest score was 144. The normed data is for under a 23 point variability- this child has 53 points variability. This happens in less than 1% of time in intelligence testing. How does an average FSIQ of 120 help this child? The truth is, it doesn't help them. It isn't an accurate representation of their intelligence or their weaknesses. These children are often stuck in the middle and can't get help for their special needs or their gifts.

@@sj4iy Ever heard of outliers? Just knowing that a person had a learning disability would be reason enough to exclude them from the set of normal people who have taken an I Q test.

@@psychicspy An outlier is still a person affected by the fact that the test was not made for them. When IQ testing determines whether someone can recieve enrichment or special education at school, that's creating a lot of problems right there.

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.

Exercise, fish oil, magnesium, are all very good at improving the vasculature and reducing risk of stroke

Oh, like Marcel Proust!

I also believe there is a misunderstanding about the whole 10% issue, it's not about only using 10% of your brain, what is really meant by this is, we only use a fraction of our mental capacity or potential, think about highly intelligent people, that are also very knowledgeable, individuals, that know 7 languages, remember, everyone's name, can do complex math in their head quickly, these people are using the same amount of their brain as everyone else, but they are also using a much higher capacity of their brains potential than others. and so many studies have been done on this, educational stimulus, at a very early age, has a major influence on how much of the brains potential we are taking advantage of, experiences, create new neural pathways, it's all about the "wirings", so under this context, it is very plausible that the average human is only using "10%" of their brains, potential.
