A few words of thanks would be greatly appreciated.

Lobotomy - Definition


A lobotomy is a surgical procedure involving the severing of the nerve fibers of a portion of the frontal lobe of the brain, more particularly the prefrontal cortex connected to the rest of the brain, including the thalamus. The prefrontal cortex of the brain comprises part of motor and cognitive function, but also the personality of the individual. The thalamus has, among other roles, that of emotional reflexes. A lobotomy was performed in cases of psychological disorders, including anxiety, to address some deep mental disorders. Lobotomies are, however, responsible for major disorders and long-term efficacy has not been proven. The lobotomy is now banned in many countries.
