Science Around You

Your brain prioritizes unexpected external sensations over your own movements to keep you safe. When you try to touch your own body, the cerebellum anticipates the feeling and actively suppresses the signal before it reaches your awareness. This neurological filtering system ensures you remain alert to potential threats or social interactions rather than being distracted by your own actions.
