Multiple-state control model for binocular motion rivalry in human

摘要

In the present study, a dichoptic motion experiment by introducing obliquely-oriented moving targets was used to probe the cortical control processing during binocular rivalry. The perceptual motion was indicated by the eye movements of the optokinetic nystagmus (OKN) slow phase. The results showed that the OKN slow phases exhibited three types of directional shifts. Two of these directional shifts tracked the stimuli (i.e., upper right (UR) or upper left (UL)), whereas the third moved purely upwards (UP). Since physically there is no upward-moving target for the visual inputs, this result supported the stimulus-feature rivalry hypothesis, in which higher cortical centers mediate interocular perceptual clustering for reassembling candidate percepts, and the error between emerged candidate and visual inputs would elicited binocular rivalry. The results lead us to figure out a multiple-state control model for binocular rivalry.
