Question

Quizplus · Accepted Answer

The cerebellum plays a key role in motor control and also in predicting the sensory consequences of one's own actions. When you try to tickle yourself, the cerebellum predicts the sensation and thus reduces the ticklish response. This is why the sensation is diminished compared to when someone else tickles you, as the unpredictability of the touch enhances the ticklish feeling.
