An Intro Into Visual System November 7, 2008
Posted by SonjaHelga in : vision , trackback
The visual system is the part of the nervous system which allows organisms to see. It interprets the information from visible light to build a representation of the world surrounding the body. The visual system has the complex task of (re)constructing a three dimensional world from a two dimensional projection of that world. The psychological manifestation of visual information is known as visual perception.
This article mostly describes the visual system of mammals, although other “higher” animals have similar visual systems. In this case, the visual system consists of:
* The eye, especially the retina
* The optic nerve
* The optic chiasma
* The optic tract
* The lateral geniculate body
* The optic radiation
* The visual cortex
