“Split Brain” is a term used to describe an early method of severing the corpus callosum and separating the two hemispheres of the brain. This was done to reduce the spread of seizures. Following this procedure differences were found between the left and right side of the brain; most of this research is attributed to Sperry .
Split brain is a relatively rare situation which is usually the result of all other options being exhausted in attempting to control epilepsy and epileptic seizures. It involves the severing of a dense group of nerve fibers which connect the left and right hemispheres of the brain. Agenesis of the corpus callosum is often congenital and is secondary to a malformation that following surgical severing seems to provide clearer left-right differences. The result of having a split brain is typically the inability to name an object that is presented within the left visual field due to the information...
