Abstract
Abstract. The neural basis of binocular rivalry has been the subject of vigorous debate. Do discrepant monocular patterns rival for awareness because of neural competition among pattern representations or monocular channels? In this article, I briefly review psychophysical and neuro-physiological evidence pertaining to both theories and discuss important new neuroimaging data which reveal that rivalry is fully resolved in monocular visual cortex. These new findings strongly suggest that interocular competition mediates binocular rivalry and that V1 plays an important role in the selection of conscious visual information. They further suggest that rivalry is not a unitary phenomenon. Interocular competition may fully account for binocular rivalry whereas a separate mechanism involving pattern competition likely accounts for monocular and stimulus rivalry. Key words: binocular rivalry, human, magnetic resonance imaging, visual perception, visual cortex A fundamental question in the fields of vision, psychology, and neuroscience is how the brain selects one of many competing visual signals for access to conscious-ness. When different monocular patterns are simultaneously presented to the two eyes, they rival for perceptual dominance such that only one monocular image is perceived at a time while the other is temporarily suppressed from aware-
