摘要The neural correlates of the motion priming were examined In normal young subjects using event-related brain potentials (ERPs) and functional magnetic resonance imaging (fMRI). Visual motion perception can be unconsciously biased in favor of a particular direction by a preceding motion in that direction. Motion priming first involved an enhancement of ERP amplitude about 100 ms following the onset of motion. The amplitudes of ERP components after 350 ms were also increased. The fMRI results suggest that the early-latency effect reflects modulation of neural responses in extrastriate cortex. Higher-level visual processing areas, including cortical regions MT/MST and the intraparietal cortices were also activated. The findings provide direct evidence that unconscious priming of motion perception is the result of interaction of direction-selective neural responses to motion stimuli. The results cannot be accounted for by refractoriness of neural responses, but instead support a theory of motion priming based on motion opponency, as proposed in computational models.; The neural correlates of the motion priming were examined In normal young subjects using event-related brain potentials (ERPs) and functional magnetic resonance imaging (fMRI).
