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]
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.
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 ...
He hammered an ice pick-like instrument, an orbitoclast, through the eye socket and swept through the frontal lobes. The transorbital or "ice pick" lobotomy was done under local anesthesia or using electroconvulsive therapy to render the patient unconscious and could be performed in mental hospitals lacking surgical facilities.

The American term lobotomy has never been used by medical writers in the UK to describe a psychosurgical operation on the frontal lobe. The standard Freeman-Watts operation, called a lobotomy in the US, was called a leucotomy in the UK. Freeman later developed a psychosurgical technique in which an instrument is inserted through the eye-socket.
A lobotomy, also known as a lobectomy or leucotomy, was a neurosurgery approach. It entailed severing the connections between the prefrontal cortex and the rest of the brain. It could be done in two ways: directly removing them or destroying them. The most common side effect was a drastic and permanent change in personality.
In 1948, in an attempt to reduce the risks and damaging effects of leucotomy, he developed a technique of his own, the rostral leucotomy, where the frontal lobes were approached from the top of the head. He still used the standard Freeman-Watts technique on some patients. By the late 1950s, he had performed about 3,000 leucotomies. [2] [3]
Moniz also referenced the experiments of Yale physiologists John Farquhar Fulton and C.F. Jacobsen, who found that removing the frontal lobes of a chimpanzee made it calmer and more cooperative. In addition, Moniz observed "changes in character and personality" among soldiers who had had injuries to their frontal lobes. [10]
