Quizplus · Accepted Answer

The corpus callosum is a bundle of nerve fibers that connects the two hemispheres of the brain. Cutting it, also known as a corpus callosotomy, would impair communication between the right and left cerebral hemispheres. This is often done as a treatment for epilepsy when seizures originate in one hemisphere and spread to the other hemisphere through the corpus callosum.
