lobotomy

A lobotomy () 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. The surgery severs most of the connections to and from the prefrontal cortex, and the anterior part of the frontal lobes of the brain.

From the 1930s until the 1970s, the treatment was used for handling psychiatric disorders as a mainstream procedure in some countries. A preoccupation with the ability to work and personal responsibility over patient well-being were contributing factors to the prevalence of lobotomies in the United States.
