Significance When we actively explore objects by touch, the brain receives two types of signals, tactile sensory inputs and signals about exploratory movement, which must be combined to perceive shape location in space. Whereas these usually come from same body part, have developed a technique separate them, directing one hand movement other. We find that separated synchronized are as if they arose hand. Our results suggest solve difficult problem multidimensional signal combination touch perception, uses simplified, source-independent representation movement.
