A study of the retinal ganglion cell which has an uncrossed bifurcating axon in the albino rat.
Injection of the fluorescent tracers, Evans blue (EB) and Primulin (Pr), or EB and 4',6-diamino-2-phenylindol dihydrochloride (DAPI), respectively, into the dorsal nucleus of the lateral geniculate body and the superior colliculus on the ipsilateral side have demonstrated the existence of retinal ganglion cells having uncrossed bifurcating axons in the albino rat. Our fluorescent labeling study confirms the existence of double-labeled cells, namely, retinal ganglion cells having bifurcating axons, in the peripheral temporoventral half (temporoventral crescent) of the ipsilateral retina, coupled with the single-labeled cells from each structure. A percentage estimation of these three kinds of labeled cells revealed that the double-labeled cells greatly occupy a majority of the entire labeled cells and no ostensible difference was evident in the proportion of double-labeled cells to the entire labeled cells between both the ipsilaterally and contralaterally projecting cell groups.
