What is lobotomy?

Lobotomy, also called prefrontal leukotomy, is a surgical procedure that severs nerve pathways connecting a lobe or lobes of the brain with other brain areas. It was formerly used as a radical treatment for individuals with severe mental disorders, including schizophrenia, manic depression, and mania. The procedure was used with the aim of calming patients who were agitated, delusional, self-destructive, or violent.
