caption_attribution_description: English: This image schematically represents optic pathways from each of the 4 quadrants of view for both eyes simultaneously. It is a pseudo-3D image based on several 2D text book descriptions. I have combined these to represent both sagittal and coronal planes in one image. The graphical work is entirely my own work.
context_page_description: The visual system comprises the sensory organ and the part of the central nervous system which gives organisms the ability to process visual detail as sight, 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 neural mechanisms underlying stereo vision, the identification and categorization of visual objects, assessing distances to and between objects, motion perception, guiding body movements in relation to the objects seen, colour vision, and more. The psychological side of visual information procesing is known as visual perception, a lack of which is called blindness. Non-image forming visual functions, independent of visual perception, include the pupillary light reflex and circadian photoentrainment.
