A motor program is an abstract representation of movement that centrally organizes and controls the many degrees of freedom involved in performing an action.p. 182 Signals transmitted through efferent and afferent pathways allow the central nervous system to anticipate, plan or guide movement. Evidence for the concept of motor programs include the following:〔p. 182 :# Processing of afferent information (feedback) is too slow for on-going regulation of rapid movements. :# Reaction time (time between “go” signal and movement initiation) increases with movement complexity, suggesting that movements are planned in advance. :# Movement is possible even without feedback from the moving limb. This is not meant to underestimate the importance of feedback information, merely that another level of control beyond feedback is used:〔 :# Before the movement as information about initial position, or perhaps to tune the spinal apparatus. :# During the movement, when it is either “monitored” for the presence of error or used directly in the modulation of movements reflexively. :# After the movement to determine the success of the response and contribute to motor learning. == Central organization == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Motor program」の詳細全文を読む スポンサード リンク
