记录正常青年人在运动知觉实验中的事件相关电位(ERPs)与功能性磁共振成像(fMRI). 结果发现某一特定方向的视觉运动知觉可以无意识地诱导其后的运动知觉偏向于同一方向;ERP早期(100ms)与晚期(350ms)成分的波幅增大;fMRI显示该早期效应反映外纹状皮层的神经调节机制,内侧颞叶(MT/MST)和顶叶内皮质的高级视觉加工区域也被激活.该结果提供了运动知觉启动效应的机制,是运动知觉刺激的方向选择性神经响应相互作用观点的直接证据,支持基于计算模型的对立的运动知觉启动理论,不支持神经反应不应期假说.
The incident-related potentials (ERPs) and functional magnetic resonance imaging (fMRI) of normal young adults in motor perception experiments were recorded. The results showed that visual motor perception in a particular direction unconsciously induced subsequent motor perceptions to bias in the same direction; the amplitude of the early (100 ms) and late (350 ms) components of ERP increased more; fMRI showed that this early effect reflected the appearance of the cortex The neuromodulatory mechanism, the medial temporal lobe (MT / MST), and the parietal lobe endocortical high vision processing region is also activated. This result provides a mechanism for the kinesthetic priming effect and is direct evidence of the view of the direction-selective neuro-responsive interaction of motor-sensory stimuli. It supports the computational model-based oppositional kinesthetic priming theory and does not support the neurorestoratory refractory hypothesis.
