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. [1]
Walter Jackson Freeman II (November 14, 1895 – May 31, 1972) was an American physician who specialized in lobotomy. [1] Wanting to simplify lobotomies so that it could be carried out by psychiatrists in psychiatric hospitals, where there were often no operating rooms, surgeons, or anesthesia and limited budgets, Freeman invented a transorbital lobotomy procedure.
Watts and Freeman wrote two books on lobotomies: Psychosurgery, Intelligence, Emotion and Social Behavior Following Prefrontal Lobotomy for Medical Disorders in 1942, and Psychosurgery in the Treatment of Mental Disorders and Intractable Pain in 1950. He is also known for carrying out the lobotomy of Rosemary Kennedy under the supervision of ...
Until Freeman introduced the technique of transorbital lobotomy, psychosurgery required the skills of a surgeon. The standard lobotomy/leucotomy involved drilling burr holes in the skull on the side of the head and inserting a cutting instrument; it was thus a "closed" operation, with the surgeon unable to see exactly what he was cutting.
All the forms of psychosurgery in use today (or used in recent years) target the limbic system, which involves structures such as the amygdala, hippocampus, certain thalamic and hypothalamic nuclei, prefrontal and orbitofrontal cortex, and cingulate gyrus—all connected by fibre pathways and thought to play a part in the regulation of emotion.

Egas Moniz performed the first leucotomy, or lobotomy in Portugal in 1935, which targets the brain's frontal lobes. [7] This was shortly thereafter adapted by Walter Freeman and James W. Watts in what is known as Freeman–Watts procedure or the standard prefrontal lobotomy. From 1946, Freeman developed the transorbital lobotomy, using a device ...
Another, different, surgical instrument also called a leucotome was introduced by Walter Freeman for use in the transorbital lobotomy. Modeled after an ice-pick, it consisted simply of a pointed shaft. It was passed through the tear duct under the eyelid and against the top of the eyesocket.
In 1980 it was suggested that electroconvulsive therapy, prefrontal lobotomy, and partial cerebral hypoxia (hypoxic-anoxic brain injury) be used to treat rage syndrome. [1] A 1974 study on prefrontal lobotomy of aggressive dogs found that 50% of lobotomized dogs died of complications. [ 19 ]
