Corpus callosotomy

Corpus callosotomy is a surgical procedure that disconnects the cerebral hemispheres resulting in a condition which is called split-brain.

Most modern callosotomies involve only the anterior portion of the corpus callosum, reflecting the fact that the frontal and temporal lobes are the most commonly involved in the genesis of seizures. The deficits from this modified procedure are milder; some patients have no side effects whatsoever.
