An energy model, a kind of stimulus-response model, of binocular neurons allows for investigation behind the computational function these disparity tuned cells play in the creation of depth perception. [1] [13] [14] [15] Energy models of binocular neurons involve the combination of monocular receptive fields that are either shifted in position ...
The visual cortex is responsible for processing the visual image. It lies at the rear of the brain (highlighted in the image), above the cerebellum. The region that receives information directly from the LGN is called the primary visual cortex (also called V1 and striate cortex). It creates a bottom-up saliency map of the visual field to guide ...
Depth perception is the ability to perceive distance to objects in the world using the visual system and visual perception. It is a major factor in perceiving the world in three dimensions Depth sensation is the corresponding term for non-human animals, since although it is known that they can sense the distance of an object, it is not known ...
For example, recent studies have shown that the V4 area is responsible for color perception in humans, and the V8 (VO1) area is responsible for shape perception, while the VO2 area, which is located between these regions and the parahippocampal cortex, integrates information about the color and shape of stimuli into a holistic image.

The partial crossing over of optic nerve fibres at the optic chiasm allows the visual cortex to receive the same hemispheric visual field from both eyes. Superimposing and processing these monocular visual signals allow the visual cortex to generate binocular and stereoscopic vision. The net result is that the right cerebral hemisphere ...
The problem of motion estimation generalizes to binocular vision when we consider occlusion or motion perception at relatively large distances, where binocular disparity is a poor cue to depth. This fundamental difficulty is referred to as the inverse problem. [14] Nonetheless, some humans do perceive motion in depth.
Experiment agreed with the general shape of this prediction and provided an explanation for the dynamics of monocular eye closure (monocular deprivation) versus binocular eye closure. [10] The experimental results are far from conclusive, but so far have favored BCM over competing theories of plasticity.
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 ...
