lobotomy

 [lo-bot´ah-me]
a form of psychosurgery consisting of cutting of nerve fibers connecting a lobe of the brain with the thalamus. In most cases the affected parts are the prefrontal or frontal lobes, the areas of the brain involved with emotion; thus the operation is referred to as prefrontal or frontal lobotomy. Once fairly common as a method of controlling violent behavior, in recent decades its use has become rare because of the development of medications for treatment of severe mental illness, such as the antipsychotics that suppress violent symptoms of psychosis.
