平面运动(MIP)与深度运动(MID)是自然界两种最基本的运动形式,但关于人类大脑对它们的感知机制上的差异,目前还不清楚。本研究采用一种比较接近人视觉经验的实验范式,采集了这两种运动情况下的128导脑电数据,对其ERP数据进行了较详细的时-空分析,结果显示MIP与MID在激活脑区、时间过程等方面均表现出了一定的差异,同时运动方向也对运动感知具有显著的影响。同时还发现MIP与MID的感知都是多脑区信息整合的结果。
Motion-in-plane (MIP) and motion-in-depth (MID) are two basic motions in nature. However, the cognition of human perception to the difference between the two movements is still unclear. In this paper, we used an experimental paradigm more close to human visual experience to recorded 128-channels EEG data, made spatio- temporal analysis on the event-related potential (ERP) in details. The results illustrated that there were some differences between MID and MIP on active brain areas and temporal courses. And the motion direction has significant effect on the perception of motion. Moreover, both MID and MIP perception seem to be the results of integration of multiple brain areas.
