The brain does not feel pain. It's the control center of the body and is responsible for processing pain signals, but it doesn't have the same pain receptors as other parts of the body. This is why neurosurgeons can operate on the brain while a patient is awake without causing them pain.
The brain lacks nociceptors, which are the nerve endings that detect damage or the threat of damage to the body. These nociceptors send signals to the spinal cord and brain, which then interprets the signals as pain.
While the brain itself doesn't feel pain, the surrounding tissues, such as the meninges (the coverings of the brain), nerve tissues, blood vessels, and skull, do have nociceptors and can cause pain. This explains why people experience headaches, which are caused by irritation or inflammation of these surrounding tissues.
However, there are conditions like congenital insensitivity to pain, where people are unable to feel pain from birth due to genetic mutations. This can lead to serious injuries as they don't experience the warning signals of pain, which helps protect the body from further damage.
