Lobotomy (Greek:λοβός lobos "lobe (of brain)"; τομή tomē "cut, slice") is a neurosurgical procedure, a form of psychosurgery, also known as a leukotomy or leucotomy (from the Greek λευκός leukos "clear, white" and tomē). It consists of cutting or scraping away most of the connections to and from the prefrontal cortex, the anterior part of the frontal lobes of the brain.
