Binocular rivalry — the alternations in perception that occur when different images are presented to the two eyes — has been the subject of intensive investigation for more than 160 years. The psychophysical properties of binocular rivalry have been well described, but newer imaging and electrophysiological techniques have not resolved the issue of where in the brain rivalry occurs. The most recent evidence supports a view of rivalry as a series of processes, each of which is implemented by… 
When Your Brain Decides What You See
It is found that perceptual alternations span the three types of rivalry, demonstrating that the brain can produce a coherent percept sourced from three different types of visual conflict.
Stimulus rivalry and binocular rivalry share a common neural substrate
It is found that flickering the stimuli generates spectral power at the tagged frequencies in both types of rivalry in the early visual cortex, which suggests that the sites of competition for stimulus rivalry and binocular rivalry may similarly include the occipital pole and middle temporal gyrus of the visual system, consistent with a low-level, binocular interpretation.
Binocular rivalry alternations and their relation to visual adaptation
An overall explanation of this intriguing perceptual phenomenon needs to also include noise as an equally fundamental process involved in the stochastic resonance of perceptual bistability.
Enhancement of bistable perception associated with visual stimulus rivalry
It is shown that it is possible to increase the incidence of stimulus rivalry by brief, periodic presentation of a composite configuration created by superimposition of the two rival stimuli.
The effects of motion on binocular rivalry between simple and complex images
The term binocular rivalry refers the perceptual alternations that occur when a different image is presented to each eye. There is an ongoing debate as to whether competition between two eyes or the
Binocular rivalry outside the scope of awareness
Evidence is provided that awareness of conflicting interocular information is not necessary for binocular rivalry to occur, and that rivalry is either instigated in higher level brain areas involved in cognitive functions like decision-making, attention, and awareness or in early visual cortex, where basic stimulus features are processed.

Binocular rivalry (BR) refers to the spontaneous, unpredictable fluctuations in visual awareness provoked by dissimilar stimulation of the two eyes. Reports of the phenomenon date back several
Hierarchy of cortical responses underlying binocular rivalry
Results from experiments in which observers' attention was diverted from the rival stimuli imply that competition between two rival stimuli involves neural circuits in V1, and attention is crucial for the consequences of this neural competition to advance to higher visual areas and promote perceptual waves.


When the brain changes its mind: interocular grouping during binocular rivalry.
It is found that pattern coherency in itself can drive perceptual alternations, and the patchworks are reassembled into coherent forms by most observers.
Binocular Rivalry and Visual Awareness: The Role of Attention
It is found that a dominant image is less likely to be suppressed when voluntary attention is directed to it, and a rivalry stimulus is more likely to become dominant if accompanied by a pop-out cue (in the same eye and proximity).

The results suggest that input-related differences in relative spike timing at an early stage of visual processing may play an important part in the phenomena both of binocular integration and rivalry; they indicate that the temporal patterning of cortical activity may be a fundamental mechanism of selection among competing stimulus representations.
Binocular rivalry : Central or peripheral selective processes?
Perceptual experience is thereby shown to reflect processes over and above the analysis of sensory information, and binocular rivalry suggests itself as a useful context in which to isolate and investigate these processes.
Stochastic properties of binocular rivalry alternations
Previous researches have demonstrated that the successive phase durations in binocular rivalry are independent. These findings are confirmed and extended to chromatic stimuli. The nature of the
A neural theory of binocular rivalry.

This article develops a neural theory of binocular rivalry that treats the phenomenon as the default outcome when binocular correspondence cannot be established, and posits the existence of monocular and binocular neurons arrayed within a functional processing module.

The activity of single neurons in monkeys trained to report their percepts when viewing ambiguous stimuli was recorded, and the activity of almost all neurons in the inferior temporal cortex and the visual areas of the cortex of superior temporal sulcus was found to be contingent upon the perceptual dominance of an effective visual stimulus.
