The physiology and anatomy of the retina are relatively well known. Physiological studies of the retina have uncovered a number of cellular and subcellular mechanisms such as the characteristics of the ion channels found in retinal neurons. Neuroanatomical studies have revealed the morphological principles governing the structure of the retina. The former data provide information about the functional role of ion channels in generating and shaping the light response of the retinal neurons. It is as yet impossible to provide a complete model of the retina. But it is now possible to identify some computational operations that the retina performs and to relate them to specific physiological mechanisms, on the basis of neuroinformatics.
