Subject: RE: [tips] Split-Brain question
I remember the woman shown in one of the video series ("The Brain"?) who
had
had her corpus callosum cut. Her name was Vicky and she said that
sometimes
one hand will reach in her closet and pick out a blouse that she doesn't
really want. And her other hand will put it back.
One thing that I haven't been able to find the answer to - but I'll bet
someone on TIPS knows - is why, in severe epilepsy or seizure disorders,
sometimes the corpus callosum is cut and sometimes - in the cases I've
seen
it was in children - a hemispherectomy is done. Cutting the corpus
callosum
seems so much less radical than removing some or all of one of the
hemispheres of the brain. Obviously, neither is wonderful, but what are
indications for one over the other?

Beth: Don't quote me on this,but I was told that the .reason for the
cut of theCC in epilepsy was to confine the seizure to only one side of the
body.
Apparentlly this is less devastating than if the total brain
was involved.
