A form of psychosurgery which involves lesioning all or part of the brain’s cingulate gyrus. Originally developed as a lobotomy alternative, it is used today to treat severe cases of chronic pain or obsessive-compulsive disorder.
Massachusetts General Hospital has an in-depth description of the surgery and the reasons to have it/not to have it here: http://neurosurgery.mgh.harvard.edu/Functional/cingulot.htm
