Based on computational principles, with as yet no direct experi(cid:173) mental validation, it has been proposed that the central nervous system (CNS) uses an internal model to simulate the dynamic be(cid:173) havior of the motor system in planning, control and learning (Sut(cid:173) ton and Barto, 1981; Ito, 1984; Kawato et aI., 1987; Jordan and Rumelhart, 1992; Miall et aI., 1993). We present experimental re(cid:173) sults and simulations based on a novel approach that investigates the temporal propagation of errors in the sensorimotor integration process. Our results provide direct support for the existence of an internal model.
