A lobotomy (Greek: lobos: Lobe of brain, tomos: "section") is a form of psychosurgery, also known as a leukotomy (from Greek leukos: clear or white and tomos meaning "section"). It consists of cutting the connections to and from, or simply destroying, the prefrontal cortex. These procedures often result in major personality changes.
