Helmholtz examined the human eye and concluded that it was incapable of producing a high quality image. Insufficient information seemed to make vision impossible. He therefore concluded that vision…

Courtesy : Audio/Visual Study See also: Two-streams hypothesis The major problem in visual perception is that what people see is not simply a translation of retinal stimuli (i.e., the image on the retina). Thus people interested in perception have long struggled to explain what visual processing does to create what is actually seen.…

Courtesy : Audio/Visual Visual perception is the ability to interpret the surrounding environment through photopic vision (daytime vision), color vision, scotopic vision (night vision), and mesopic vision (twilight vision), using light in the visible spectrum reflected by objects in the environment. This is different from visual acuity, which refers to how clearly a person sees (for example “20/20 vision”). A person can have…

When these three conditions are isolated and balance is tested, it has been found that vision is the most significant contributor…

Whereas a V1 neuron may respond selectively to a line segment of a particular orientation in a particular retinotopic location, neurons in the lateral occipital complex respond…

At this point, the information coming from both eyes is combined and then splits according to the visual field. The corresponding halves of…
