  1. Lobotomy

    Lobotomy is a neurosurgical procedure, a form of psychosurgery, also known as a leukotomy or leucotomy. 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. While the procedure, initially termed a leucotomy, has been controversial since its inception in 1935, it was a mainstream procedure for more than two decades, prescribed for psychiatric conditions – this despite general recognition of frequent and serious side-effects. The originator of the procedure, António Egas Moniz, shared the Nobel Prize for Physiology or Medicine of 1949 for the "discovery of the therapeutic value of leucotomy in certain psychoses", although the awarding of the prize has been subject to controversy. The usage of the procedure increased dramatically in some countries from the early 1940s and into the 1950s; by 1951, almost 20,000 lobotomies had been performed in the United States. Following the introduction of antipsychotic medications in the mid-1950s lobotomy underwent a gradual but definite decline.
