WebThe nerve fiber layer (NFL) of the rat retina is composed of unmyelinated ganglion cell axons en route to the optic nerve. These axons, which become myelinated after entering the optic nerve, range in size from 0.12 to 0.8 μm, with a few reaching 2.0 μm. The peak frequency is 0.3 to 0.4 μm (Hildebrand and Waxman, 1983). http://www.ajnr.org/content/27/9/1815 goldman sachs fargo nd
