Binocular rivalry is a phenomenon of visual perception in which perception alternates between different images presented to each eye. [1] An image demonstrating binocular rivalry. If one views the image with red-cyan 3D glasses, the text will alternate between red and blue. 3D red cyan glasses are recommended to view this image correctly.
Neural adaptation can affect the relative strength of the visual stimuli and can affect perceptual suppression in events such as binocular rivalry. Several research have shown that manipulating neural adaption can allow one to control perceptual dominance during binocular rivalry; rivalry dominance durations are longer in situations where ...
Binocular neurons in the dorsal and ventral pathways combine to create depth perception, however, the two pathways perform differ in the type of stereo computation they perform. [7] The dorsal pathway generally performs a cross-correlation based upon the region of the different retinal images, while the ventral pathway fixes the multiple ...
Suppression of an eye is a subconscious adaptation by a person's brain to eliminate the symptoms of disorders of binocular vision such as strabismus, convergence insufficiency and aniseikonia. The brain can eliminate double vision by ignoring all or part of the image of one of the eyes.
It can erase an image presented at the fovea (which usually is much more resistant to perceptual suppression, unlike, for example, crowding), in every trial (unlike binocular rivalry), for a longer duration (>1 sec, unlike backward masking), with an excellent control of timing (unlike binocular rivalry). It has been widely exploited to tackle ...
This established the neural basis for stereopsis. Their findings were disputed by David Hubel and Torsten Wiesel, although they eventually conceded when they found similar neurons in the monkey visual cortex. [39] In the 1980s, Gian Poggio and others found neurons in V2 of the monkey brain that responded to the depth of random-dot stereograms. [40]
[medical citation needed] In studies done on primate brains, a corollary discharge pathway has been found to begin in the superior colliculus. [4] After receiving current information about the visual field, a corollary discharge signal is sent from the superior colliculus to the frontal eye field, via the medial dorsal nucleus of the thalamus.

Examples of visually ambiguous patterns. From top to bottom: Necker cube, Schroeder stairs and a figure that can be interpreted as black or white arrows. Multistable perception (or bistable perception) is a perceptual phenomenon in which an observer experiences an unpredictable sequence of spontaneous subjective changes.
