When the sensory system receives an ambiguous signal, human perception often switches spontaneously between two different interpretations. This phenomenon is called bistable perception, and has been considered important to understanding sensory system. In this study, we investigated the intervals of spontaneous switching, defined as reversal time τ, to examine the temporal dynamics of bistable perception. We also studied the multi-modal feature of bistable switching by applying auditory noise with the visual stimuli. Our hypothesis is that auditory noise would significantly alter the reversal time of bistable visual perception. By building a computational model, we could explain the influence of auditory noise on the reversal time.
Our result shows the multi-modal features of bistable perception in visual system and provides evidence of multi-modal integration process in the sensory perception for ambiguous information. We suggest that auditory noise can regulate the temporal switching of bistable perception in neural circuit level.
