A surgical procedure involving an incision or dissection of the brain.
From cerebro- (brain) and -tomy (a suffix meaning 'surgical cutting,' from Greek tome). This medical term was more common in earlier eras when brain surgery was more experimental and less precise.
Cerebrotomy sounds terrifying, but it's actually a historical predecessor to modern neurosurgery—it reminds us that brain surgery didn't exist at all before the late 1800s.
