These centre surround structures are not physical in the sense that one cannot see them by staining samples of tissue and examining the retina's anatomy. The centre surround structures are logical (i.e., mathematically abstract) in the sense that they depend on the connection strengths between ganglion and bipolar cells .

In the center of the retina is the optic nerve, a circular to oval white area measuring about 2 x 1.5 mm across. From the center of the optic nerve radiates the ...

The primary layers of the retina from outermost surface to innermost surface: Pigment epithelium - supporting cells for the neural portion of the retina ( photopigment regeneration, blood) it is also dark with melanin which decreases light scatter within the eye.

The retina is a thin layer of tissue that lines the back of the eye on the inside. It is located near the optic nerve. The purpose of the retina is to receive light that the lens has focused, convert the light into neural signals, and send these signals on.
