Principle of binocular vision with horopter shown. In biology, binocular vision is a type of vision in which an animal has two eyes capable of facing the same direction to perceive a single three-dimensional image of its surroundings. Binocular vision does not typically refer to vision where an animal has eyes on opposite sides of its head and ...
Disparity attraction and repulsion is believed to be directly related to the physiological properties of binocular neurons in the visual cortex. [1] Use of the stereo model has allowed for interpretation of the source of differing peak locations found in disparity tuning curves of some cells in visual cortex.
It has long been recognized that full binocular vision, including stereopsis, is an important factor in the stabilization of post-surgical outcome of strabismus corrections. Many persons lacking stereopsis have (or have had) visible strabismus , which is known to have a potential socioeconomic impact on children and adults.
Distribution of rods and cones along a line passing through the fovea and the blind spot of a human eye [1]. A blind spot, scotoma, is an obscuration of the visual field.A particular blind spot known as the physiological blind spot, "blind point", or punctum caecum in medical literature, is the place in the visual field that corresponds to the lack of light-detecting photoreceptor cells on the ...
The Worth Four Light Test, also known as the Worth's four dot test or W4LT, is a clinical test mainly used for assessing a patient's degree of binocular vision and binocular single vision. Binocular vision involves an image being projected by each eye simultaneously into an area in space and being fused into a single image.
The ocular dominance columns cover the primary (striate) visual cortex, with the exception of monocular regions of the cortical map corresponding to peripheral vision and the blind spot. [7] If the columns corresponding to one eye were colored, a pattern similar to that shown in the accompanying figure would be visible when looking at the ...
Suppression of an eye is a subconscious adaptation by a person's brain to eliminate the symptoms of disorders of binocular vision such as strabismus, convergence insufficiency and aniseikonia. The brain can eliminate double vision by ignoring all or part of the image of one of the eyes.
The lingual gyrus is the hypothetical location of V4 in macaque monkeys. In humans, this area is called hV4. The fusiform gyrus is the hypothetical location of V4α, a secondary area for colour processing. More: Colour centre. Visual area V4 is one of the visual areas in the extrastriate visual cortex.
