- n. severing the corpus callosum so that communication between the cerebral hemispheres is interrupted (in cases of severe intractable epilepsy)
Sorry, no etymologies found.
All of this makes me wonder - is the optic chiasm cut during the corpus callosotomy and if so, does the person lack depth perception?
Last night's episode of Grey's Anatomy depicted a patient who underwent a "corpus callosotomy" and then was unable to identify his wife, baby, and a simple object in the room a cup placed in front of him.
A full corpus callosotomy creates some interesting side effects - but not the severe one depicted on the show of not being able to identify anything.
