A person who undergoes split-brain surgery is most likely to do so in an effort to treat epileptic seizures that is unresponsive to drug treatments.
The split-brain surgery is a procedure that is performed to treat epileptic seizures which are caused by a disturbance in the electrical activity of the brain. The split-brain surgery involves cutting the corpus callosum (a group of fibers that connects the brain’s left and right hemispheres). After this procedure, the two hemispheres do not exchange information as adequately as before and it can lead to split-brain syndrome (a condition that influences behavior and agency).
