Which layer contains the synapses between bipolar cells and ganglion cells?

• A. Nerve Fiber Layer (NFL)
• B. Outer Plexiform Layer (OPL)
• C. Inner Plexiform Layer (IPL)
• D. Inner Nuclear Layer (INL)

Answer: (C)

In the retina, the signal from bipolar cells to ganglion cells is transmitted in the inner plexiform layer. This layer sits between the inner nuclear layer (where bipolar cells have their bodies) and the nerve fiber layer (where the ganglion cell axons travel to the optic nerve). The inner plexiform layer is where bipolar cell terminals synapse onto ganglion cells, with amacrine cells also modulating the connection. The outer plexiform layer is where photoreceptors connect to bipolar and horizontal cells, while the nerve fiber layer contains the axons of ganglion cells.
