is a psychosurgical
procedure involving selective destruction of connective nerve
fibers in the frontal lobe of the brain
. It was usually performed with the purpose of alleviating mental illness
and chronic pain symptoms. The use of lobotomy is now regarded as a disastrously mistaken episode in surgical history, as its effects are often unpredictable and wide-ranging.
Bilateral cingulotomy is a modern psychosurgical technique which has replaced the lobotomy.
