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

点击翻译按钮获取中文摘要

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.
