Early Split Brain Research Gazzaniga

Documentary. Rare video. The end is CUT OFF so here's the rest of the narration:




"The question becomes: What happens when you allow both hands together to try and solve the problem? And what we find out is that they fight over each other. One hand knows how to do it and one hand does not. And so they more or less squabble. And the reason for this is that the hemispheres are disconnected. The right hemisphere controls the left hand and the left hemisphere controls the right hand and these are almost mutually independent systems as if two people were fighting over performing th task. One knew how and the other d one would fight for dominance over the situation. What have we gained from this research into split-brains? It is now possible to localize in one half brain, basic mental processes like learning and memory. This cuts the complexities of brain research almost in half so that in the future we can expect to achieve deeper insights into the mechanics of how the brain really works." END

Actually it cures epilepsy that was otherwise killing these people. They discovered these strange effects after the fact.

This is a current technique for improving quality of life for people with debilitating epilepsy.

@mrjollypantsjolly fucking moralfags still don't get it. Nothing is true, everything is permitted. I seriously hope you don't still believe in right and wrong/heaven and hell. come on, its 2011.

Thanks for uploading. Very fascinating. Also, quite horrible for the animals. Nonetheless, its very very interesting stuff, though I wonder what has truly been gained in terms of knowledge.

@beenn15 hahaha.

[beenn15]

wow. this is fascinating.  If I had seen this in high school, I probably would've been a brain surgeon by now.

THIS IS VERY VERY INTERESTING....I ENJOYED IT MUCH.

@koeber They've altered the procedure though so they cut the anterior end of the Corpus Callosum but leave the posterior end in tact, this means that we don't see the same effects because visual crossover (though not motor cross-over) is retained.
