Evidence for Perceptual “Trapping” and Adaptation in Multistable Binocular Rivalry
When a different pattern is presented to each eye, the perceived image spontaneously alternates between the two patterns (binocular rivalry); the dynamics of these bistable alternations are known to be stochastic. Examining multistable binocular rivalry (involving four dominant percepts), we demonstrated path dependence and on-line adaptation, which were equivalent whether perceived patterns we...
متن کاملHigh-Level Binocular Rivalry Effects
Binocular rivalry (BR) occurs when the brain cannot fuse percepts from the two eyes because they are different. We review results relating to an ongoing controversy regarding the cortical site of the BR mechanism. Some BR qualities suggest it is low-level: (1) BR, as its name implies, is usually between eyes and only low-levels have access to utrocular information. (2) All input to one eye is s...
متن کاملHysteresis effects in stereopsis and binocular rivalry
Neural hysteresis plays a fundamental role in stereopsis and reveals the existence of positive feedback at the cortical level [Wilson, H. R., & Cowan, J. D. (1973). A mathematical theory of the functional dynamics of cortical and thalamic nervous tissue. Kybernetik 13(2), 55-80]. We measured hysteresis as a function of orientation disparity in tilted gratings in which a transition is perceived ...
متن کاملBinocular Rivalry
When two different images are shown, one to each eye, we don't always see a mix of the two. In cases when the images differ in atleast one attribute we may see only one image at a time and this alternates between the two images. (eg: Horizontal and vertical gratings differ in the direction of grating. When horizontal grating is shown to say right eye and vertical grating to left eye we see only...
متن کاملBinocular rivalry
What is binocular rivalry? In humans and animals with forward facing eyes, the two eyes provide views of the world that are only subtly different from one another. In each eye, the lens focuses light into a two-dimensional image on the retina. In normal vision, the disparity between the retinal images provides a stereoscopic cue to the third spatial dimension, depth. But when the eyes are prese...
