Your Brain May Have Amazing Powers

I've never given much credence to the "only use 10% of our brains" urban legend, but this article, Savant for a Day, is making me reconsider. I'd like to see controlled, double-blind studies, but Snyder's machine already sounds very interesting -- hey, anyone can learn to draw, but I want to flip a switch to put my brain into calculator mode. EM-brain experimentation has taken off since Michael Persinger's work and other recent research.

    On the "10% of your brain" legend, here is a pretty cool writeup. The best quote from the article:

    In other words, the "humans only use 10% of their brains" canard would more correctly be phrased "humans only use 10% of their brains for walking around and smelling things"...

    At first I just chalked up the down webserver to some poor schmed's server going belly-up under the weight of the slashdot effect. But no, that link is sitting on the New York Times server:

    But for some reason I can get to the NYT.com frontpage, albeit after some delay. Their search results do not show anything matching that article name ("Savant for a Day") and Google doesn't have anything either.

    Ca bien. Will just have to wait for it to die off.

  3. It doesn't make it sound like a legend... by Nindalf · · Score: 3, Interesting

    "they were of normal or above-normal intelligence ... their cerebral hemispheres had been compressed into a slab less than an inch thick"

    If kids can lose large portions of their brains and still grow up bright and healthy, then I think that suggests pretty strongly that most of the brain is either functionally redundant or simply unused.

    That's a great quote about the 10%, though.

    What I want to know is why large animals need a larger brain to handle their bodies, and brain:body mass ratios are considered more important than absolute brain mass. It shouldn't require more data processing just to run a larger body, when most of its processes are regulated without the brain. Furthermore, it sounds like that wasn't the case for dinosaurs, some of which had little bird-sized brains in enormous bodies.

      If this was the case, then you should be able to remove a large portion of the brain from an adult and they would remain bright and healthy.
      I don't think anyone would argue that a child who has lost a large part of their brain is going to be functionally equivalent to a full brained peer.
      Most of the human brain is used for body control and less exotic processes as those higher functions we attribute to our intelligence; language, problem solving, consciousness, etc. These take place on the neocortex, which is the portion of our brain that looks swollen when compared to typical primate brains. Even the neocortex is mostly white matter -- neurons that channel information -- compared with the gray matter which are the neurons that do the "computation". The gray matter is only on the surface of the brain, it doesn't go very deep, maybe several millimeters. Larger brains are necessary for larger mammals not as an efficient method of cooling blood, but also regulating many of the body functions and controlling a larger network of musculature.
      Brain/body mass ratios are a useful index insofar as they offer a useful conjecture about which animal should have, comparitively, higher mental functioning -- more neocortical development since the brain materials necessary to govern the body and movement are fairly standard. Humans and dolphins have the highest brain to body mass index, by far.

    Ever stand in front of a door for twenty minutes because you thought it was locked, and it really wasn't, you just couldn't figure out how to turn a doorknob?

    That's me. Aside from being totally inadept mechanically, I also can't draw, can't understand music to the point where I can't differentiate between different melodies, can't see color, can't reliably do arithmatic computation, can't speak foreign languages, and have no athletic ability.

    I know my limitations. Just thinking "hmm, one day, I shall surpass my limitations and use all the latent abilities in my brain" is wishful thinking. The vast majority of people are stupid, uninsightful, self-absorbed, and pathetic. To assume that you, yourself, are not part of the majority is simply a lie put forward by your self-absorbed sense of self-esteem. Your mind lies to you, makes you think you're special, somehow different from the vast majority of peons on this earth, when you're really not. It's a very destructive lie - it prevents you from realizing that you don't even have the capacity to understand what's really going on 90% of the time.

  5. Drawing on the right side of the Brain by scotay · · Score: 4, Interesting

    When I was in high school, this Book Drawing on the Right of the Brain was quite popular with the art teachers. It was said to be a new way to teach people to draw. From what I remember it worked quite nicely for me and did not require magnetic fields.

    To use the technique, we were told to lay out our drawing pads, place our hands into the middle of the pad and never to look at our hands as we were drawing. We were supposed to focus on what we were drawing and then try to remember where we left our hands in space without actually seeing where they were. I was told that I could glance down at my hand from time to time, but that I should not look at my hands while actually drawing.

    Whatever the technique did do my cognitive process seemed to work. My normal drawing style looked like figures 1 and 2. While I used the right side technique, my drawing looked like figure 3, with my lines conveying more movement and being more a stylized reproduction.

    Maybe this guyâ(TM)s apparatus is simply forcing the participants not to look at their hands while drawing. Seems a lot more controls would be needed to say magnetic fields have anything to do with this phenomenon.

  7. Brain Wars by limekiller4 · · Score: 5, Interesting

    From the article:
    "While I drew, Snyder continued his lecture. ''You could call this a creativity-amplifying machine. It's a way of altering our states of mind without taking drugs like mescaline. You can make people see the raw data of the world as it is. As it is actually represented in the unconscious mind of all of us.''"

    What I find seriously funny is the fact that while drug use is seriously shunned around most of the so-called "developed" world, there will be no such outcry over such mental manipulation utilizing this method. So it isn't the end we're concerned about, it's the vehicle.

    Do you realize that roughly 6x as many people have died either outright or by drowning after inhaling fumes while behind a motorboat since 1991 than have while taking MDMA (ecstacy)? And that doesn't even include the people who drowned and nobody suspected the poisoning.

    Do you realize that between cirrhosis of the liver (alcohol) and deaths resulting from drunk driving accidents there are 60,000 killed in the US every year? And ephedra, creatine and ecstacy are the problems?

    Sorry for going off on a rant here. I welcome this sort of research. But it does point out that what Americans are against is not people doing things to their own bodies. What people fear is a boogeyman that has been fueled by a multi-billion dollar industry that they need to maintain. Ie, jobs.

    Along these lines, my brother-in-law gets autism headaches where he hears a guitar riff and can copy it instantly, and can look at a row of lockers and say how many there are without counting. Was I ever shocked to be talking with him one day, he pauses, says "48", says he has a headache, and goes home. It turns out there were 48 chairs in that room.

    If that kind of autism can be turned on with a "switch", why not other aspects?

    And FWIW, which often isn't much in the realm of science, it makes sense that it could be important from a survival standpoint to hide some hypothetical lower structures which, say, count 87 toothpicks, and just send to the upper level an exectutive summary, like 'lots of toothpicks'.

  10. We use 100% of our brains - just not all at once. by Beardo+the+Bearded · · Score: 5, Interesting

    Come on, guys. Every single one of us has seen brain scan images of people remembering or doodling. In those images, different parts of the brain do different tasks.

    For example, I don't use my occipital lobe when I'm not looking at stuff. Once I start doing visual work, ol' occy goes to work.

    The idea that we only use 10% of our brain is silly. We're not latent psychics or telekinetics, nor does the other 90% hold penguins. We just don't use all of our brain all of the time. Throughout the day, though, you'll use all of your brain, unless part has been removed via surgery, accident, or believing the US "President".

  11. There's a name for 100% brain usage by nimblebrain · · Score: 3, Interesting

    It's called a grand mal seizure. Well, even that is likely less than 100% ;) I had always thought the origin of the 10% myth was a misquote on 10% "at a time" - thanks for some more of the origins regarding it. It's pretty unlikely that there's masses of unused neurons hanging around. Neurons are kept alive by having connections - past their initial growing stages, they die by apoptosis voluntarily. This is not a bad thing - one condition, synaesthesia, arises from neurons connecting auditory and visual parts of the brain not dying off. Most of the 'information' in neurons comes from the connections; on the order of 10,000 in and 10,000 out - the stained cell micrographs you see in textbooks do the real picture no justice. Thoughts are akin to a travelling contour amplitude modulation map (sorry, everyone, your brain operate in AM, not FM :) - the 'contour map' can suffer some degradation of detail from dying neurons or forgetfulness before losing meaning. Walter J Freeman's book "How The Brain Makes Up Its Mind" is full of interesting information. Someone should help him make a next edition in English (instead of merely using purportedly English words as "limit cycles" and "zero-point attractors") to widen the audience for the fascinating discoveries in the book.

    If this kind of stuff gives you a charge, you HAVE to check out Paul Pietsch's work on trying to relate brain to mind. He swaps brains in amphibians, mushes them up, etc., and watches the wee beasties more or less get along.

    I thought of this because of the question raised in the article about identity: "It probably would change people's ideas of themselves, to say nothing of their ideas of artistic talent."

    Another interesting angle is to look into the way the brain may rely on quantum processes... Apollo 14 astronaut Dr. Edgar Mitchell has done some interesting, if nigh-kooky, summaries of work on this.
