Question

Quizplus · Accepted Answer

The corpus callosum is sometimes surgically severed in patients who suffer from severe epilepsy. This is done to prevent the spread of epileptic seizures from one hemisphere of the brain to the other. By cutting the corpus callosum, the two hemispheres are essentially isolated from one another, which can reduce the occurrence of seizures.
