Your brain actually doesn't have pain receptors. It doesn't even have touch receptors. The brain is a command center. It helps drive and govern changes in the organs of the body. But your brain doesn't move, at least not much. It can move a little bit fluid moves within it. But as long as you're healthy, it's not moving that much. Your brain has no sensation of its own, in fact, when they do brain surgery on people, they will the size or put some anesthesia on the scalp. They'll cut away the skin there so that people don't feel anything. They'll use some anesthesia they'll peel back the skin and then they'll use a, let's call it what it is, it's a bone saw. And they basically saw open a little window in the skull. I've actually done this before and seen this before. I've done this many times before, and once you're inside the brain, you can put electrodes in there and you can put various things in there, of course, all for therapeutic purposes. And you do that without any anesthesia to the actual brain tissue, because it has no receptors to sense anything. It doesn't have pain receptors. It doesn't have pressure receptors. None of that, when you have a headache in your head, feels like it's too much pressure, well that's because of here's that lie outside the brain.
