Abstract

This article reviews the anatomy and physiology of the visual system. The physical stimulus is coded by several separate and parallel pathways at multiple sites in the nervous system. We outline the major parallel pathways of the system, from their beginning in the retina, to the multiple cortical areas that receive visual input. Emphasis has been placed on the functional properties of the neurons of these pathways and the various cortical processing areas as they are currently known. Clinical syndromes as a result of damage to specific visual cortical areas are also described.
