Influence of motor learning on contingent negative variation while performing simultaneous movement of upper and lower limbs

记录了3个受试者组（篮球组、足球组和一般成人组）的上肢和下肢同时控制的运动表现和关联性负变（CNV）。如果上下肢运动之间的干扰程度较大，则记录到晚期CNV振幅的大振幅。这些数据表明，大脑的准备状态，同时控制的上肢和下肢是不同的肢体运动的自动化。

Motor performance of simultaneous control of the upper and lower limbs and contingent negative variation (CNV) were recorded for 3 subject groups (basketball-, soccer- and general adult-groups). In case that degree of interference between the upper and lower limbs movements was large, large amplitude of late CNV amplitude was recorded. These data suggest that cerebral state of preparation for simultaneous control of the upper and lower limbs is different with respect to automatization of limb movement.
