I was reading about alien hand syndrome about an hour ago, something peaked my interest. When where a person has had the two hemispheres of the brain seperated it leaves them susceptible to this condition, and from what I understand it's when the other hemisphere, the non dominant one, gains control of.. well your arm for instance. so I have to wonder something, if the dominant hemisphere is open to experience alien hand syndrome due to what is going on in the other hemisphere, does the other hemisphere function as a person and experience 'alien entire body' syndrome? Also, when you get a hemispherectomy, or have a large portion of your brain removed... doesn't the organ require some kind of support? and should you refrain from head banging? Because it seems liek there's a lot of free space, a vast open cavity for a less stable physical structure to move around and tear itself up in. Just an aside question. It seems like taking out a large portion of it without supporting it would make it less "structurally stable". Dunno, can't find an answer for this question specifically.
