A brief hammer tap applied passively (by the experimenter) to the forearm elicits a short-latency reflex response in the forearm flexors and extensors. When the same tap is performed actively (by the subject) using the opposite forearm, the reflex response is preceded by a short-lasting anticipatory reduction in the muscle activity appearing around the impact. This anticipatory reduction is interpreted as an alternative mode of feedforward motor control associated with damping of kinetic impulses generated within the bimanual system.
由实验者被动地对前臂进行短暂的锤击,会在前臂屈肌和伸肌中引发短潜伏期的反射反应。当受试者用对侧前臂主动进行相同的锤击时,在反射反应之前,冲击周围的肌肉活动会出现短暂的预期性降低。这种预期性降低被解释为一种与抑制双手系统内产生的动力冲动相关的前馈运动控制的替代模式。
