Abstract(in English) | In this study, we clarified the neural dynamics for the biological motion (BM) perception by measuring an event-related potentials. The subjects were shown BM or scrambled motion (SM) as a control stimulus. In the SM, each point had the same velocity vector as in the BM, but the initial starting positions were randomized. The perception of both BM and SM elicited negative peaks at around 200 (N200) and 240 ms (N240). Furthermore, both negative peaks were significantly larger in the BM condition than in the SM condition over the bilateral occipitotemporal region. We speculated that component N200 reflected motion processing, and N240 reflected BM processing. Further study showed that the attentional process was also involved. |
