Expression and Function of the Endocannabinoid System in the Retina and the Visual Brain

Figure 1

Schematic illustration representing the organization of the mouse retina. Rod (R) and cone (blue/C) photoreceptors have their cell bodies in the outer nuclear layer (ONL) and extend inner (IS) and outer (OS) segments. Photoreceptors axons synapse in the outer plexiform layer (OPL) with horizontal (yellow/H) and bipolar (magenta/RBC-CBC) cells. The inner nuclear layer (INL) also contains amacrine (red/A) and Müller cells (M). Bipolar cells synapse to amacrine and ganglion (blue/G) cells in the inner plexiform layer (IPL). Ganglion cell axons form the optic nerve in the ganglion cell layer (GCL) and carry signals to the brain.
