Binocular fusion and rivalry

The fact that inputs from two eyes feed into a common mechanism gives rise to several interesting problems. Signals from the two eyes that arise from the same object must be distinguished from signals that arise from spurious superimposition of non-matching stimuli. Matching signals falling on neighbouring points on the two retinas project to the same region in the visual cortex and fuse to create the impression of one image. Non-matching images falling on the same region in the two eyes rival for access to the visual system. This chapter deals with these issues. The discussions cover binocular fusion; dichoptic colour mixture; binocular rivalry; the spatial zones of rivalry; the generality of binocular suppression; aftereffects from suppressed images; rivalry and stereopsis; cognition and binocular rivalry; models of binocular rivalry; and the neurology of binocular rivalry.

Keywords: dichoptic colour mixture; binocular rivalry; binocular suppression; stereopsis; visual system
