A lobotomy (from Greek λοβός (lobos) 'lobe', and τομή (tomē) 'cut, slice') or leucotomy is a discredited form of neurosurgical treatment for psychiatric disorder or neurological disorder (e.g. epilepsy, depression) that involves severing connections in the brain's prefrontal cortex.[2] The surgery causes most of the connections to and from the prefrontal cortex, the anterior part of the frontal lobes of the brain, to be severed.
