Binocular rivalry in split-brain observers.
During binocular rivalry, visual perception switches between a stimulus viewed by one eye and a different stimulus viewed by the other. We studied rivalry in split-brain observers to test two explanations. Rivalry could reflect switching of activity between the cerebral hemispheres, or switching by a structure in the right frontoparietal cortex. From these two theories, we predict no rivalry wh...
متن کاملVisual grouping on binocular rivalry in a split-brain observer
We studied the effects of visual grouping on binocular rivalry in the left and right hemispheres of a split-brain observer, JW. In Experiments 1 and 2, we compared responses to traditional rivalry stimuli (e.g., a red vertical grating presented to the left eye and a green horizontal grating presented to the right eye) with responses to Diaz-Caneja stimuli (i.e., half of each grating was present...
متن کاملBinocular rivalry, brain stimulation and bipolar disorder
Mechanistic understanding of binocular rivalry (BR) has drawn upon psychophysical, electrophysiological and brain-imaging studies. The first brain stimulation approach occurred in the late 1990s and assessed a new mechanistic proposal, the interhemispheric switch (IHS) hypothesis. Both caloric vestibular stimulation (CVS) and transcranial magnetic stimulation (TMS) modulated rivalry predominanc...
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...
