Do you feel ticklish when you tickle yourself? Normally, you wouldn’t, unless someone else tickles you. It happens because the cerebellum area of the brain, which monitors movements, predicts the sensations caused by your own movements. Then, it sends a signal to other parts of the nervous system to cancel these sensations. But some rare individuals can actually feel ticklish on their own. If you’re not among them, touching a new texture that the brain doesn’t yet recognize or using a scalp massager can help to excite your nerves and bring relaxation.
