About 70% of people with epilepsy can be treated with medication to prevent seizures from occurring. If medication does not work, surgery is an option for some patients. One of the procedures involves cutting the brain so that the seizures cannot be spread to other parts of the brain. A common goal of the surgical procedure to treat epileptic seizures is to reduce the connection between the two hemispheres of the brain. By cutting through this structure, an epileptic seizure occurring on one side of the brain will not be spread to the other side. Identify the structure that connects the two hemispheres of the brain.arrow_forward
