将来自视觉、听觉和本体感觉系统的传入感觉信息整合到运动程序的执行和更新中，在音乐表演中熟练的顺序动作的控制和获得中起着至关重要的作用。然而，传统的行为和神经生理学技术已经应用于研究简单的运动行为，限制了对熟练音乐表演背后的在线感觉运动整合过程的阐明。在此，我们提出了两种新的技术来研究听觉和本体感受反馈在钢琴演奏中的作用。首先，一个闭环无创脑刺激系统由经颅磁刺激、运动传感器和微型计算机组成，该系统能够评估钢琴演奏过程中听觉-运动整合的随时间变化的皮层过程。其次，一个能够操纵钢琴琴键重量的力场系统，可以根据所获得的反馈来表征运动适应，这可以阐明钢琴内部表征的形成。神经生理学和心理物理学实验的结果提供了证据，证明这些系统是分离音乐表演中感觉运动整合的计算过程和神经过程的有效手段。
An integration of afferent sensory information from the visual, auditory, and proprioceptive systems into execution and update of motor programs plays crucial roles in control and acquisition of skillful sequential movements in musical performance. However, conventional behavioral and neurophysiological techniques that have been applied to study simplistic motor behaviors limit elucidating online sensorimotor integration processes underlying skillful musical performance. Here, we propose two novel techniques that were developed to investigate the roles of auditory and proprioceptive feedback in piano performance. First, a closed‐loop noninvasive brain stimulation system that consists of transcranial magnetic stimulation, a motion sensor, and a microcomputer enabled to assess time‐varying cortical processes subserving auditory–motor integration during piano playing. Second, a force‐field system capable of manipulating the weight of a piano key allowed for characterizing movement adaptation based on the feedback obtained, which can shed light on the formation of an internal representation of the piano. Results of neurophysiological and psychophysics experiments provided evidence validating these systems as effective means for disentangling computational and neural processes of sensorimotor integration in musical performance.
