Sensorimotor interaction in human motor control

点击翻译按钮获取中文摘要

These studies focus on the interplay of sensory and motor function in the control of movement and its perception. The long-term goal is to understand how sensory information is integrated in the control of movement and how sensory function on its own contributes to motor learning. The present studies deal in particular with the idea that sensory perception is modified by learning. The studies extend from an assessment of the degree to which somatosensory input related to speech production affects a speaker's sound classification and, more generally, whether speech motor learning warps a speaker's auditory map. Parallel studies of studies of arm movement address the idea that motor learning results in changes to somatosensory function. The studies are linked by a common interest in the sensory basis of motor learning and control and also a common methodology, the use of servo-controlled robotic manipulators to deliver precise mechanical perturbations to the arms or the jaw.
