It may be the height of irony. The brain is the control center that processes pain, telling us when something is wrong or when we need to pay closer attention to a particular part of the body. Yet the brain itself is not capable of feeling pain because it has no pain receptors. What about headaches, then? Surely we feel pain with a headache, as anyone who suffers from migraines can tell you.
Actually, headache pain does not come from the brain itself; it comes from the layers of tissue that shield the brain and skull.
