The higher magnification afforded by the electron microscope allows better resolution of rod and cone photoreceptors. ... In the fovea, however, where there are only cone photoreceptors, the most central cones are even thinner than the average rod at about 1.5 microns diameter. Inner segment regions of both rods and cones...

A simplistic wiring diagram of the retina emphasizes only the sensory photoreceptors and the ganglion cells with a few interneurons connecting the two cell types such as seen in the figure below.

Results of the present study show that EAAT4 is present in the outer segments, a nonsynaptic region of photoreceptors, where it might provide a feedback mechanism for sensing extracellular glutamate or serve as an outer barrier to prevent glutamate from escaping from the retina.

The retina is the back part of the eye that contains the cells that respond to light. These specialized cells are called photoreceptors. There are 2 types of photoreceptors in the retina: rods and cones.

The retina contains two types of photoreceptors, rods and cones. The rods are more numerous, some 120 million, and are more sensitive than the cones. However, they are not sensitive to color. ... The rods are incredibly efficient photoreceptors. More than one thousand times as sensitive as the cones, they can reportedly...

The actual photoreceptors are the rods and cones, but the cells that transmit to the brain are the ganglion cells. The axons of these ganglion cells make up the optic nerve, the single route by which information leaves the eye.
