The brain cannot feel pain as there are no pain receptors. That is the reason brain surgeons can perform surgery while the patient is completely awake. In fact, they prefer the patient is awake, so that they know immediately if anything has gone wrong. But some cases are not suited to be performed as awake surgery.

Why do we get headaches if the brain has no pain receptors?

The brain itself does not feel pain because there are nonociceptors located in brain tissue itself. … In some situations, chemicals released from blood vessels near the dura and pia can activate nociceptors, resulting in headaches, such as migraines.
