It is fair to say, however, that no area of visual neuroscience has enjoyed greater progress than the physiology of visual motion perception. Publications dealing with visual motion perception and its neural bases would fill volumes, and the topic remains central within the visual neuroscience literature even today. This chapter aims to provide an overview of brain mechanisms underlying human motion perception. The chapter comprises four sections. We begin with a short review of the motion pathways in the primate visual system, emphasizing work from single-cell recordings in Old World monkeys; more extensive reviews of this literature appear elsewhere.1,2 With this backdrop in place, the next three sections concentrate on striate and extra-striate areas in the human brain that are implicated in the perception of motion.
