Error correction mechanisms in perception of body movements : Learning of sensorimotor representations can enhance error corrections.

We investigated whether accuracy of the position estimates of a moving body segment (e.g., hand) can be improved with motor control practice without vision. Through an intensive training of motor control skills, subjects could become to consciously perceive dynamic hand positions by relying on non-visual information, even though vision is a major source for error corrections. Moreover, without vision, afferent sensory information from stretched muscles and tendons plays a more important role in conscious perception of dynamic hand position than downstream information to prime movers.
