The study of visual motion perception entails analyzing the optical information at the eye psychophysically and the neural mechanisms that detect and transform this information physiologically. At both levels of analysis, progress is evident; however, that which links these two levels is still unknown. This chapter probes the links between the physiological and behavioral sides of center-surround interactions in visual motion perception. It discusses the logic that links visual perception and physiology, the presence of physiology in the center-surround organization of receptive fields and of psychophysics in apparent perceptual correlates of this center-surround mechanism, and two potential perceptual functions of this center-surround motion mechanism.

Keywords: macroscopic perception; physiology; center-surround; figure-ground segregation; motion signals
