<unk>  is a palliative surgical procedure for the treatment of medically refractory epilepsy. In this procedure the<unk>  callosum is cut through in an effort to limit the spread of epileptic activity between the two halves of the brain. After the operation the brain has much more difficulty sending messages between the hemispheres. Although the<unk>  callosum is the largest white matter tract connecting the hemispheres, some limited interhemispheric communication is still possible via the anterior commissure and posterior commissure. "Efficacy and relatively low permanent morbidity in<unk>  for medically intractable epilepsy have been demonstrated by more than six decades of experience. In addition to seizure reduction, behavior and quality of life may improve."
