    retina can be dramatically different. Even so, the primate visual system segments the relevant parts of the shape from the scene and then perceives and recognizes the appropriate object with a speed and precision that is unmatched by even the most cutting-edge machine vision systems.

The retina is approximately mm thick and lines the back of the eye. The optic nerve contains the ganglion cell axons running to the brain and, additionally, incoming blood vessels that open into the retina to vascularize the retinal layers and neurons (Fig. A radial section of a portion of the retina reveals that the ganglion cells.

The retina’s projection neuron, the retinal ganglion cell, has less than 1% the soma-dendritic volume of a cortical or hippocampal pyramidal cell. Although the retina forms a sheet of tissue only ~ μm thick, its neural networks carry out feats of image processing that were unimagined even a few years ago (Gollisch and Meister, ).

Understanding the organization of the vertebrate retina has been the goal of many talented visual scientists during the past years. With Cajal's () anatomic descriptions of the cell types that constitute the retina in a number of vertebrate species, and with an early understanding of the role of visual purple in photochemistry in combination with psychophysical studies of adaptation.

In the vertebrate retina, this type of modular organization is of paramount importance for the proper functioning of the neural circuitry, and regular mosaics are found among all classes of. The function of any neural circuit is governed by connectivity of neurons in the circuit and the computations performed by the neurons.

Recent research on retinal function has substantially advanced understanding in both areas. First, visual information is transmitted to the brain by at least 17 distinct retinal ganglion cell types defined by characteristic morphology, light response.

The vertebrate retina is that part of the central nervous system where multiple parallel representations of the visual world first emerge.

And like other parts of the brain, the retina is a beautiful and complex piece of neural machinery, although it has taken nearly years for the degree and nature of its complexity to be fully appreciated.

Introduction Primate retinal cell types. The mammalian retina displays a diversity of cell types and functionally distinct synaptic pathways (Masland, ).Much of this anatomical diversity has been recently summarized (Rodieck, ; Sterling, ; Vaney, ): at least 2 horizontal cell and 10 bipolar cell populations transmit signals in parallel from photoreceptors to ganglion by: Chapter 1 The Retinal Representation An Overview of the Retina In this chapter we will review the structure of the retina and its role in organizing visual information.
