A lobotomy, or leucotomy, was a form of psychosurgery, a neurosurgical treatment of a mental disorder that involves severing connections in the brain's prefrontal cortex. Most of the connections to and from the prefrontal cortex, the anterior part of the frontal lobes of the brain, are severed.

How does a lobotomy affect a person?

The intended effect of a lobotomy is reduced tension or agitation, and many early patients did exhibit those changes. However, many also showed other effects, such as apathy, passivity, lack of initiative, poor ability to concentrate, and a generally decreased depth and intensity of their emotional response to life.

Are lobotomies still performed today?

Lobotomy is rarely, if ever, performed today, and if it is, "it's a much more elegant procedure," Lerner said. "You're not going in with an ice pick and monkeying around." The removal of specific brain areas (psychosurgery) is only used to treat patients for whom all other treatments have failed.
