Although configuration is important for the perception of biological motion, it is not known whether the processing of configuration occurs early or subsequent to local motion processing. Here we report significantly greater adaptation of the N1 event-related potential elicited by a point-light walker (PLW) following an intact PLW relative to a scrambled PLW, static intact PLW, or no adaptation. These results indicate that the N1 to biological motion reflects the activity of a neural population involved in the early integration of form and motion, suggesting that configuration is processed at the same time as, or prior to, local motion.
尽管构型对于生物运动的感知很重要，但尚不清楚构型的处理是在局部运动处理之前还是之后进行。在此，我们报告，相对于杂乱排列的点光步行者（PLW）、静态完整的PLW或无适应刺激，在完整的PLW之后，由点光步行者引发的N1事件相关电位的适应程度显著更高。这些结果表明，对生物运动的N1反映了参与形式和运动早期整合的神经群体的活动，这表明构型与局部运动是同时处理或在其之前处理的。
