Tractotomy involves cutting a nerve tract and is done to alleviate certain types of chronic pain. Rhizotomy is the surgical cutting of nerve roots, not nerve tracts. Vagotomy is the surgical removal of the vagus nerve to treat certain conditions such as ulcers, and trephination is the drilling of a hole in the skull, typically done in ancient times to release pressure or evil spirits.
