Your Brain May Have Amazing Powers 498

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.

      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?

        I have borderline high-functioning autism myself. Regarding "special talents" (with me anyway) - it comes and goes. I can't switch it on/ off. Regarding the chairs if there were 6 rows of 8 chairs it isn't that hard to count. The ability to remember musical melodies isn't that difficult - and can be learned. It's part of most musician's training to be able to memorise not just a riff but entire pages of music. If you've taken a music exam you have to sing back a few phrases played to you - which is not far off playing them. I get the tension headaches too - one of the downsides of the frustration caused by having a communication disorder and being misunderstood.

        In my own experience I remember a migraine I had come on at work and it transformed me into a savant (of sorts) by giving me a mini Tourette's episode. I couldn't actually tell my colleagues in so many words why I was being a bit odd (apparently muttering "motherfucker" every third word is normal for me when I'm working on something tricky - who knew?) but I developed an amazing ability to communicate my predicament by pointing at my head, grimacing, and saying "shit motherfucker gnnn!"

        Who knew that talent lay latent within me, just waiting for its release through the method of blinding and nauseating pain?

      In college, we'd drop acid and go to the arcade (early 1980's) and play video games. I was a pretty good Missile Command player normally, but on LSD, I was basically perfect. The game was slow, smooth, and also had a weird 3D quality (it looked kind of like claymation animation).

      By LAWRENCE OSBORNE

      n a concrete basement at the University of Sydney, I sat in a chair waiting to have my brain altered by an electromagnetic pulse. My forehead was connected, by a series of electrodes, to a machine that looked something like an old-fashioned beauty-salon hair dryer and was sunnily described to me as a ''Danish-made transcranial magnetic stimulator.'' This was not just any old Danish-made transcranial magnetic stimulator, however; this was the Medtronic Mag Pro, and it was being operated by Allan Snyder, one of the world's most remarkable scientists of human cognition.

      Nonetheless, the anticipation of electricity being beamed into my frontal lobes (and the consent form I had just signed) made me a bit nervous. Snyder found that amusing. ''Oh, relax now!'' he said in the thick local accent he has acquired since moving here from America. ''I've done it on myself a hundred times. This is Australia. Legally, it's far more difficult to damage people in Australia than it is in the United States.''

      ''Damage?'' I groaned.

      ''You're not going to be damaged,'' he said. ''You're going to be enhanced.''

      The Medtronic was originally developed as a tool for brain surgery: by stimulating or slowing down specific regions of the brain, it allowed doctors to monitor the effects of surgery in real time. But it also produced, they noted, strange and unexpected effects on patients' mental functions: one minute they would lose the ability to speak, another minute they would speak easily but would make odd linguistic errors and so on. A number of researchers started to look into the possibilities, but one in particular intrigued Snyder: that people undergoing transcranial magnetic stimulation, or TMS, could suddenly exhibit savant intelligence -- those isolated pockets of geniuslike mental ability that most often appear in autistic people.

      Snyder is an impish presence, the very opposite of a venerable professor, let alone an internationally acclaimed scientist. There is a whiff of Woody Allen about him. Did I really want him, I couldn't help thinking, rewiring my hard drive? ''We're not changing your brain physically,'' he assured me. ''You'll only experience differences in your thought processes while you're actually on the machine.'' His assistant made a few final adjustments to the electrodes, and then, as everyone stood back, Snyder flicked the switch.

      A series of electromagnetic pulses were being directed into my frontal lobes, but I felt nothing. Snyder instructed me to draw something. ''What would you like to draw?'' he said merrily. ''A cat? You like drawing cats? Cats it is.''

      I've seen a million cats in my life, so when I close my eyes, I have no trouble picturing them. But what does a cat really look like, and how do you put it down on paper? I gave it a try but came up with some sort of stick figure, perhaps an insect.

      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.''

      Two minutes after I started the first drawing, I was instructed to try again. After another two minutes, I tried a third cat, and then in due course a fourth. Then the experiment was over, and the electrodes were removed. I looked down at my work. The first felines were boxy and stiffly unconvincing. But after I had been subjected to about 10 minutes of transcranial magnetic stimulation, their tails had grown more vibrant, more nervous; their faces were personable and convincing. They were even beginning to wear clever expressions.

      I could hardly recognize them as my own drawings, though I had watched myself render each one, in all its loving detail. Somehow over the course of a very few minutes, and with no additional instruction, I had gone from an incompetent draftsman to a very imp

      It wouldn't make much sense for us to have evolved brains that were 10 times larger than they had to be -- If such a huge portion wasn't being used, those with larger brains wouldn't have been selected above those with smaller brains. Those individuals with the most efficient use of brain would have been selected since they wouldn't have to supply all the extra brain matter with oxygen and food.
      • For some reason I had justified this by assuming that we used approximately 10% at any given time, but that overall just about every neuron was used in some capacity.

      Since most of a modern CPU's transistor count is cache memory you'ill probably find that outside the control unit at any one time even less than 10% of the transistors are active. If you include the number of transistors present for main memory in the mix that percentage gets even lower.

      "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.
      • i think they have big brains because they have big heads.. something needs to fill up that big head..
      • 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, w

      • It shouldn't require more data processing just to run a larger body

        Why shouldn't it? Most animals don't do much planning or even abstract thinking- the most important task for the neurons in the brain is to operate each and every muscular fiber in the limbs and organs.

        Let us say "It shouldn't require more Human Resources staff to run a larger corporation". That's obviously wrong- of course you need more as you have more things under control.

      But walking around and smelling things takes a lot of brain power (at least as much as reasoning does). Think about it. When you walk around and smell things your brain is doing a lot of work. Your brian is processing your vision, smells, and balance. Your brain is also regulating your heartbeat, breathing, and other bodily fun

      Even if the elitism of that idea doesn't bother, you, consider that smart people often spend a large portion of their time and energy trying to convince dumb people that their good ideas are in fact good ideas, or trying to explain their ideas to dumb people so that the dumb people can use them effectively. Being surrounded by smart people would make you (as a smart person) much more effective than trying to get your work done with the help of dumb people.

    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.
    • Yup Yup.

      "Don't draw the object, draw the space around the object" was a zen moment for me.

      Most people draw "symbols" of what they see like "a head is a circle, a neck is a tube" and they just break down entire objects like that and it looks like crap.

      But by having people draw the space around the object, it forces them out of "symbol mode" because the space doesn't have a symbol you can identify with and break down, just the actual lines.

      It's like why you can usually draw a picture better if you draw it

    As I recall from college anthropology, human childbirth is painful (and sometimes even fatal) precisely because our craniums are so large, relative to other mammals and relative to the size of our frames. (Humans have the highest ratio of brain mass to body mass; whales come in second.) If so much of our brain mass were hypothetically unnecessary, then humans with smaller brains would be more likely to pass on their genes, as those childbirths would less frequently be fatal. Over time, humans would come to have much smaller craniums (90% smaller, if the urban myth were true), not the large craniums that we currently possess. The fact that evolution is willing to pay such a high penalty (increased childbirth fatalities) for large brains indicates that there must be an offsetting evolutionary advantage to having large brains. The notion that much of our brain is therefore "unused" doesn't really make sense from an evolutionary standpoint.

      Then why do I have an appendix? (Or slim body hairs?)

      Evolution does not look at any one characteristic. It looks at the whole of the being. And, between equally fit species, there's still a measure of chance.

      Let's ignore the obvious rebuttal to your point (use of the brain's savant abilities is proportional; if we have a brain half the design, we might have half of the all-around intelligence) and focus on the evolutionary advantages of having unused brain tissue.

      First off, we're able to survive brain damage much easier. Being able to be thwacked in the head and still bring food home--and maybe go out and hunt some more the next day--is an obvious evolutionary advantage.

      Secondly, it increases mating. Having a bigger brain means our heads are shaped different--in a more asthetically pleasing fashion. The face is a human's primary means of identification and emotional communication--a clearer face is an obvious evolutionary advantage, within the species.

      Thirdly, it's entirely possible that over the uncounted generations of prehistory, human-ancestor-groups who had savants among them simply outperformed other human-ancestor-groups who did not, thus neccistating a retention of the savant abilities. Not a clear evolutionary advantage, but a distinct possibility.

      While your childbirth arugment is a good one, for it to work we'd need to have some mechanism to actually shrink brain mass at the start. Bugger me if I can think of one that'd work--larger hips would be a much easier evolutionary adaptation.

        I don't think I agree with anything you wrote :-) Just reading through, and this is longer than I intended, but what the hell...

        Then why do I have an appendix? (Or slim body hairs?)

        Because there is very little selective pressure to remove these low-cost (in evolutionary terms) additions to the body. This is assuming that you can get rid of X without affecting Y, which is a heck of an assumption - most of our body parts are created/regulated by the interaction over time of *lots* of different genetic codes, your overall genetic code is not a blueprint you can just erase part of... Besides, they're not useful *now*. They presumably were *once*, and they may yet be again. Not in our lifetime, I suspect :-) but possibly in the future...

        Let's ignore the obvious rebuttal to your point (use of the brain's savant abilities is proportional; if we have a brain half the design, we might have half of the all-around intelligence) and focus on the evolutionary advantages of having unused brain tissue.

        How do you *know* it's proportional ? It may be highly non-linear in nature. Intelligence could be an emergent property, as opposed to intrinsic. There could be a minimum (or maximum) neuron-quantity threshold for intelligence to occur, the decision-surface for relative intelligence could be as complex as a fractal plane. We don't know.

        First off, we're able to survive brain damage much easier. Being able to be thwacked in the head and still bring food home--and maybe go out and hunt some more the next day--is an obvious evolutionary advantage.

        I think you're overlooking the incredibly difficult process humans go through in childbirth. The non-assisted mortality rate (for both mother and child) is far higher than any other mammalian species on the planet. Primate females almost always give birth without excessive labour. Human females labour can last over several hours, although today the child is more likely to be induced or surgically delivered. Only 200 years ago, death in childbirth was commonplace for those who could not afford assistance.

        In contrast, being hit on the head hard enough to significantly break the skull will pretty much cause damage whatever size brain you have. Since all the higher-order functionality is on the outside of the brain (grey matter), that's the area that would be damaged anyway. If you don't break the skull, you're likely to just get a bruise either way, so long as you don't make a habit of it...

        Don't forget that (unless our ancestors were particularly keen on headbutting cliffs) this would be an effect on 1 person. The do-or-die childbirth thing is an issue for every human born. I suspect nature might come down on the side of the majority...


        Secondly, it increases mating. Having a bigger brain means our heads are shaped different--in a more asthetically pleasing fashion. The face is a human's primary means of identification and emotional communication--a clearer face is an obvious evolutionary advantage, within the species.

        Um. No. If we all had faces the size of pygmy monkeys, we'd probably have designs on our chests or backs, or some other method of recognition. Sexual preference is closely tied to genetic fitness, not the other way around.

        Consider that healthy-but-pug-ugly A has a 85% chance of surviving to breeding-age (and hanging around afterwards for protection etc.) because he's got strong arms. Handsome bigheaded B has only a 50% chance of making it, but he looks really cool. Unfortunately for B, the numbers are against him. No matter how many doting females are queueing up (hah!), if he only has a 50% chance of making it, his genes (and those of the doting females, since they choose B) are far more likely to be swept down evolution's sewer. The corollary is that the female

    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.

    "Two minutes after I started the first drawing, I was instructed to try again. After another two minutes, I tried a third cat, and then in due course a fourth. Then the experiment was over, and the electrodes were removed. I looked down at my work. The first felines were boxy and stiffly unconvincing. But after I had been subjected to about 10 minutes of transcranial magnetic stimulation, their tails had grown more vibrant, more nervous; their faces were personable and convincing. They were even beginning to wear clever expressions. I could hardly recognize them as my own drawings, though I had watched myself render each one, in all its loving detail. Somehow over the course of a very few minutes, and with no additional instruction, I had gone from an incompetent draftsman to a very impressive artist of the feline form."

    I would think a more convincing experiment would be to start with the machine turned on for the full "10 minutes", the cat drawing made, then the machine turned off and another made. If this is correct then the second should actually be worse than the first.

    The idea that the ability to draw better cats improves as you practice doesn't seem terribly startling.

      I can think of all sorts of variations on this experiment. I really want one of these machines!

      For example, do the experiment they did on one group. Do a control group. Then do a pre-treatment on both groups (control and experimental). Does the machine actually cause you to learn faster? Can the author actually draw at a vastly superior level now that he not connected to the machine?

      Or does the machine provide temporary amplification. I imagine that it is something in between. Often, when I have studied a problem, I gain a huge amount of insight into it. Afterwards, I look back upon the work I have done, am *very* surprised that it turned out so well, but end up at a higher level of skill overall.

      If this machine is anything like the way it is described, I'll trade a kidney for one.

If I read it correctly, the point is that we might be able to gain certain savant abilities by turning off parts of our brains that are responsible for other very valuable abilities. It might be really valuable to be abale to do this to yourself for a short period when you have to do certain kinds of tasks, but it is not like we would want to go through our lives wearing a headband that would keep us in this kind of state.

    This is almost certainly garbage. I'm working in a transcranial magnetic stimulation lab right now, and I've never even heard of the guy doing this stuff. However, the people who criticize his work are basically the most respected people doing TMS right now. I get the sense that he's trying to infer a meaningful pattern from a small number of poorly designed tests.

    The usual effect of TMS is just to slow you down by a couple seconds at whatever you're doing. For example, right now we're doing this experiment where we flash words on a screen and have the subject read them out loud. Then eventually we just put a * up on the screen, and they have to recall the last word they saw. By changing the device to send pulses into different parts of the brain, you can find out what is responsible for what. The subjects slow down a bit when you're hitting the right part of the brain.

    I mean, this guy could be insanely revolutionary and in five years we'll all be using his machines on our heads to make us geniuses... but I don't think so.

    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.
