“…In the INL a few very large cells with light-staining large nuclei were identified as displaced ganglion cells (DGCs; Reiner et al, 1979;Fite et al, 1981;Prada et al, 1989;Kalloniatis and Napper, 1996). These cells displayed the strong Gluϩ and Aspϩ, faint GABAϩ and light to moderate Glyϩ in both in the central (Figs.…”

“…unicuspis contrasts with the larval sea lamprey, P. marinus, where 43-66% of all labeled ganglion cells were found in the INL (Rubinson & Cain, 1989). However, the greatest contrast exists with respect to gnathostome vertebrates where only 0.35-2% of the displaced ganglion cells are found in a comparable topographic position in the inner nuclear layer (Linden, 1987;Dann & Buhl, 1987;Collin, 1988;Dunlop et al, 1989;Prada et al, 1989).

The distribution of ganglion cells in the retina of the silver lamprey, Ichthyomyzon unicuspis, was revealed by retrograde labeling from the optic nerve with horseradish peroxidase (HRP) and fluorescent-labeled dextrans in live animals and with the fluorescent dye Dil in aldehyde-fixed tissue. The majority of ganglion cells (74%) termed the "outer ganglion cells," are multipolar and are located at the vitread boundary of the inner nuclear layer. The remaining ganglion cells (26%), termed the "inner ganglion cells" are bipolar and are distributed in a sublamina within the inner plexiform layer. The dense, dendritic meshwork of the outer ganglion cells is largely restricted to the sclerad half of the inner plexiform layer with some cells possessing dendrites which pass through the inner nuclear layer to terminate within the outer plexiform layer. The dendrites of the inner ganglion cells form a thin, dendritic network apposing the inner limiting membrane. Axons from both populations of ganglion cells originate from dendrites or the soma and form fascicles lying adjacent to the outer ganglion cell somata.Retinopetal fibers, originating from bilaterally distributed neurons of the tegmental midbrain, were thin and varicose and ran parallel to the ganglion cell axons to terminate either with a varicose enlargement or a few short sidebranches in the sclerad third of the inner plexiform layer. The unusual organization of the lamprey retina and outgroup comparison with hagfish suggests that agnathans share a presumably primitive type of retinal ganglion cell organization compared to that of gnathostomes.

“…The presence of axons or axon-like processes related to 'ama crine cells' has been reported in the retina of other vertebrates [23][24][25][26]. Flowever, ganglion cells displaced to the amacrine cell layer are currently observed in the avian retina [27], and in the pigeon, some of these displaced ganglion cells (DGCs) identified by retro grade axonal transport, are immunoreactive to TH. Such THI D G C s represent more than half the population of THI cells [20.…”

Dopaminergic Interplexif orm Cells in the Retina of Pigmented and Hypopigmented Quails (Coturnix coturnix japonica)

Interplexiform cells (IPCs) have not been previously described as a component of the population of tyrosine hydroxylase (TH) immunoreactive (presumably dopaminergic) cells in the avian retina. In this study, carried out in both pigmented and imperfect albino mutant quails (Coturnix coturnix japonica), we initially describe TH immunoreactive cells in the inner nuclear layer whose internal dendritic arborization extends into strata 1 3 and 4/5 of the inner plexiform layer. Then, we describe ascending processes arising from the somata or proximal dendrites of these cells. These sclerally directed processes (100-1,000 μm long) run across the inner nuclear layer to terminate within the outer plexiform layer, sometimes even reaching the outer nuclear layer. Hence, the cells bearing such processes correspond well with the definition of IPCs. The number of scleral processes is higher in mutant (48 ± 19/retina) than in normal (12 ± 10/retina) quails and are distributed throughout the retina except the area surrounding the pecten. Comparison of biochemical assays for dopamine in the two strains reveals a significantly higher dopamine content in the mutant quails which could be related to its increased number of dopaminergic IPC processes.
