Binocular rivalry and visual awareness.
Physiological studies of binocular rivalry have provided important clues to the relationship between neural activity in the brain and visual awareness. However, uncertainty about these insights has been raised by a recent study showing that the events underlying binocular rivalry occur earlier in the visual pathway than was previously thought.
متن کاملBinocular rivalry outside the scope of awareness.
The human visual system usually receives input from two eyes that each capture a slightly different perspective of the world. Conscious visual perception, on the other hand, is unitary, and the brain uses the minor disparity between the two retinal projections as an important cue to reconstruct and perceive depth. This mechanism of binocular fusion falls apart when the input to the two eyes bec...
متن کاملWhat is Grouping during Binocular Rivalry?
During binocular rivalry, perception alternates between dissimilar images presented dichoptically. Although perception during rivalry is believed to originate from competition at a local level, different rivalry zones are not independent: rival targets that are spaced apart but have similar features tend to be dominant at the same time. We investigated grouping of spatially separated rival targ...
متن کاملBinocular Rivalry and Visual Awareness in Human Extrastriate Cortex
We used functional magnetic resonance imaging (fMRI) to monitor stimulus-selective responses of the human fusiform face area (FFA) and parahippocampal place area (PPA) during binocular rivalry in which a face and a house stimulus were presented to different eyes. Though retinal stimulation remained constant, subjects perceived changes from house to face that were accompanied by increasing FFA a...
متن کاملThe initial interactions underlying binocular rivalry require visual awareness.
Current theories of binocular vision suggest that the neural processes that resolve interocular conflict do not involve a single brain region but occur at multiple stages of visual processing. Here, using an adaptation paradigm, we explore the initial mechanisms involved in selecting a stimulus for perceptual dominance during binocular rivalry. When one or both eyes briefly viewed an adapting g...
