New evidence of an unrecognized visual process
(Medical Xpress) -- We don’t see only what meets the eye. The visual system constantly takes in ambiguous stimuli, weighs its options, and decides what it perceives. This normally happens effortlessly. Sometimes, however, ...

Visual system
The visual system is the part of the central nervous system which enables organisms to see. It interprets the information from visible light to build a representation of the world surrounding the body. The visual system accomplishes a number of complex tasks, including the reception of light, and the formation of monocular representations; the construction of a binocular perception from a pair of two dimensional projections; the identification and categorization of visual objects; assessing distances to and between objects; and guiding body movements to visual objects. The psychological manifestation of visual information is known as visual perception.
