Binocular 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 کاملThe Spatial Origin of a Perceptual Transition in Binocular Rivalry
When the left and the right eye are simultaneously presented with incompatible images at overlapping retinal locations, an observer typically reports perceiving only one of the two images at a time. This phenomenon is called binocular rivalry. Perception during binocular rivalry is not stable; one of the images is perceptually dominant for a certain duration (typically in the order of a few sec...
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...
متن کاملCenter–surround interactions in visual motion processing during binocular rivalry
When each eye is confronted with a dissimilar stimulus, the percept will generally alternate between the two. This phenomenon is known as binocular rivalry. Although binocular rivalry occurs at locations where targets overlap spatially, the area surrounding rivalrous targets can modulate their dominance. Here we show that during binocular rivalry of oppositely moving gratings, a surrounding gra...
متن کاملNeuropsychological Evidence of High-Level Processing in Binocular Rivalry
One of the most fascinating and challenging questions of cognitive neurosciences is what are the neural correlates of consciousness. We try to answer this question by studying patients having a dissociation between conscious perception and sensory stimulation. We studied patients with right brain damage (RBD) involving unilateral spatial neglect (USN). USN follows a lesion in the right frontopa...
