Retinal Neurons
The mature retina contains five classes of neurons: photoreceptors (purple), horizontal cells (yellow), bipolar neurons (green), amacrine cells (pink and blue), and ganglion cells (pink and blue). In this cross section of an adult mouse retina, only a subset of bipolar cells, “the ON bipolar cells” are visible by their expression of GFP. The pink and blue speckled striations at the bottom of the image mark the fiber layer, which contains the ganglion cell axons that will form the optic nerve.
