The purpose of this study was to determine whether the late component of the contingent negative variation (CNV) in a S1-S2-respond paradigm shares critical features with the Bereitschaftspotential (BP) prior to self-paced voluntary movements. In a group of 8 subjects, the late CNV and the BP exhibited: (a) similar effects of response speed variation, (b) corresponding influences of subjective factors, and (c) a similar scalp distribution with the exception that the BP was much more lateralized. In contrast, no such relationships were found between early CNV and BP.
本研究的目的是确定在S1-S2-反应范式中，关联负变（CNV）的晚期成分是否与自定步速的自主运动之前的运动准备电位（BP）具有关键特征。在一组8名受试者中，晚期CNV和BP表现出：（a）反应速度变化的相似效应，（b）主观因素的相应影响，以及（c）相似的头皮分布，但BP的侧向化程度更高。相比之下，早期CNV和BP之间未发现此类关系。
