Although your brain registers pain in the rest of your body, it can't feel pain itself. While the skull requires anesthesia during brain surgery, the brain doesn't. There are no pain sensors for the brain. Surgeons can operate on the brain while a patient is fully awake, able to talk and answer questions. Experiments during these surgeries can help scientists learn more about how the brain works.
