3. Brain-Splitting

The cerebellum, which is the largest part of the brain, can be divided down the middle into two hemispheres. A hemispherectomy is the surgical process that removes one cerebral hemisphere of the brain. Pioneering neurosurgeon Walter Dandy originally developed the technique to treat brain tumors. In the 1960s and 70s, the operation was rare and fraught with complications –CSF leakage, deep and superficial infections –but the procedure has evolved and is commonly used today to treat extreme seizures brought on by epilepsy. The operation is done mostly on children because they display more neuroplasticity, which  that allows the neurons in the remaining side of the brain to take over many of the functions from the half that was cut away.
