I thought the lecture that professor Peterson gave on split brained people was very interesting. Separating the two hemispheres by severing the corpus callosum is a treatment often used as a last resort to help people that suffer from severe seizures. This procedure disconnects the two sides of the brain and they can no longer communicate. I think it is really interesting how after the surgery, patients will do things without knowing that they are doing it such as taking an article of clothing off after just putting it on with the other hand. The plasticity of the brain however eventually fixes that and they are able to carry on just as anyone else does with less seizures. Or can they? Since the two hemispheres of their brain can no longer communicate with each other anything that only enters the right side of their brain is rendered unknown by the person. As long as something enters both sides of the brain though the person can recognize it just as anyone else does. I was just curious as to whether or not they have any other side affects from this procedure other than not being able to recognize things that solely enter the right brain.
