Why does the brain have no pain receptors? Shouldn’t it considering it’s one of the most vital organs.
In: 4
While the brain itself doesn’t have pain receptors, the tissues surrounding it have them. So humans aren’t just going to be oblivious to things like head trauma. Additionally, prior to the invention of brain surgery there wasn’t really anything that could be done about injury/disease inside the brain, so there is little survival advantage in being able to feel it.
