A Hole in The Head examines the process of drilling a hole in one's head - trepanation - for the purpose of attaining a higher level of consciousness. This procedure, used by the ancient Egyptians, Incas, and others, might increase brain blood volume and thereby improve brain metabolism.
People who have trepanned themselves, as well as respected neurosurgeons and anthropologists, weigh in.
