Culture definitions for lobotomy lobotomy [ (luh- bot-uh-mee, loh- bot-uh-mee) ]
A surgical incision into one or more of the
nerve masses in the front of the brain. A lobotomy may be performed for the relief of certain mental disorders, although it has been largely abandoned in favor of less radical treatments. Note
Because people who have had a lobotomy often become quite passive after the operation, the term is often used to refer to someone who shows a lack of response or reaction: “She was so tired she just sat there as if she had been lobotomized.”
