Which layer primarily houses the cell bodies of the ganglion cells?

• A. Nerve Fiber Layer (NFL)
• B. Ganglion Cell Layer (GCL)
• C. Inner Plexiform Layer (IPL)
• D. Outer Nuclear Layer (ONL)

Answer: (B)

The main thing to know is where retinal neurons have their cell bodies organized. Ganglion cells are the neurons that send signals from the retina to the brain, and their cell bodies are located in the Ganglion Cell Layer. Their dendrites reach into the inner plexiform layer to receive input, while their axons bundle together to form the optic nerve and travel through the nerve fiber layer toward the brain. So, when asked which layer mainly houses the cell bodies of the ganglion cells, the correct layer is the Ganglion Cell Layer. A little context: the outer nuclear layer contains photoreceptor nuclei, and the inner plexiform layer is where synapses between bipolar/amacrine cells and ganglion cells occur. In the fovea, some ganglion cells can be displaced, but the standard location remains the Ganglion Cell Layer.
