Visual system 视觉系统
(重定向自Visual)
The visual system is the part of the central nervous system which gives organisms the ability to process visual detail, as well as enabling the formation of several non-image photo response functions. It detects and interprets information from visible light to build a representation of the surrounding environment. The visual system carries out a number of complex tasks, including the reception of light and the formation of monocular representations; the buildup of a nuclear
binocular pe****tion from a pair of two dimensional projections; the identification and categorization of visual objects; assessing distances to and between objects; and guiding body movements in relation to the objects seen. The psychological process of visual information is known as visual pe****tion, a lack of which is called blindness. Non-image forming visual functions, independent of visual pe****tion, include the pupillary light reflex (PLR) and circadian photoentrainment.
