Figure 1 Arrangement of neurons in the central retina and in the peripheral retina. There are two main specializations in the central retina. First, the central retina contains a specialized region, the fovea, in which each cone photoreceptor has a private line to the rest of the retina: when a cone synapses on a bipolar cell, that cell then synapses on one retinal ganglion cell. In the peripheral retina there is progressive convergence of several cones onto a bipolar cell. Second, in the fovea a long axon separates the synapse of a cone from the light-sensitive portion of the cone. Light can thus reach a foveal cone without having to pass through the neurons of the inner retina. Both of these specializations serve to increase the spatial resolution of the central retina.
