Which structure carries the axons that transmit visual information toward the brain?

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

Answer: (A)

Visual information travels from the retina to the brain via the axons of retinal ganglion cells. These axons originate in the ganglion cell layer and bundle together to form the optic nerve, traveling through the nerve fiber layer as they move toward the optic disc. So the nerve fiber layer is the layer that contains the axons carrying the signal outward. The other layers serve different roles: the ganglion cell layer holds the cell bodies of the ganglion cells; the inner plexiform layer is where bipolar cells connect with ganglion cells; the outer nuclear layer contains photoreceptor cell bodies.
