Fig. 1. Photomicrographs showing G O immunoreactivity in non-mammalian retinae. A, goldfish; B, frog (Xenopus laevis): C, turtle;
D, chicken. PE, pigmented epithelium; RC, rods and cones; ON(L), outer nuclear layer; OP(L), outer plexiform layer; IN(L), inner
nuclear layer: IP(L), inner plexiform layer; GC(L), ganglion cell layer; NF(L), nerve fiber layer. The magnificatioli of all the photographs
of Figs. 1 and 2 are the same to allow comparison of some species differences in the distribution pattern of G,, within the retina. |
