while laying out on a warm day. You feel something on the bottom of your foot. An ant is making its way up. So you brush it off. Usually a brush like that would feel ticklish. Why not this time? Because your brain's ability to anticipate your own touch can cancel out your own tickle. The feeling of a tickle arises from two forms of pressure on sensitive parts of your body. A light pressure. Like when the aunt was crawling up your foot triggers a tickle sensation known as nice mrs making you want to scratch or wipe it away. A tickle from greater pressure known as gargle is is is what we usually associate when someone tickles you. This may make you tense up, jolt or laugh, but even if you tried it's unlikely you can tickle yourself. That's because your brain cerebellum predicts when you are about to apply pressure to your own body. The cerebellum communicates with other parts of your brain sending signals when and where you're moving and how much pressure you are likely to apply when you touch something. Since your brain has information to execute and sense your own touch. It can reduce activity in the somatosensory cortex, the brain area that helps you respond to your sense of pressure. This cools your reaction to your own touch and allows you to get back to your beach day
