Document Summary
Callosal syndrome, friend autopsy, completely fine, but only one brain hemisphere, only one cerebral hemisphere to be fully functional, area 18: stereo vision, corpus callosum: bridging two hemispheres, callosal agenesis. Was thought to be useless: doctor: one ward 20% mortality childbirths, other ward 2% Why: dissection room nearby, people didn"t wash their hands. Doctor told them to wash hands, and mortality rate dropped to 2% in both: doctor was attacked and ridiculed for discovering germs caused disease, and people should wash their hands Seizure locus: small clump of misbehaving neurons that causes seizures: can be removed. Since it originates in one hemisphere, they thought if they cut the corpus callosum they would confine the seizures to one hemisphere: they cut it, and at first the patient was mute. Occasional signs of disconnect: one hand hugs, other hand pushes away: on casual inspection, patients without corpus callosum seem completely normal.
