| contents | Retinal ganglion cell topography in the masked greenling Hexagrammos octogrammus (Pallas, 1814) (Pisces, Scorpaeniformes, Hexagrammidae). Kondrashev, Sergei Pushchin, Igor Aleskerov, Naig Animals Retinal Ganglion Cells Perciformes Neuroglia Amacrine Cells The spatial arrangement of retinal neurons determines to a certain extent visual acuity and sensitivity. Despite a large number of studies dealing with retinal topography, there are gaps in our knowledge on the issue. We addressed the spatial arrangement of retinal ganglion cells in the masked greenling, a marine demersal fish. The combined proportion of displaced amacrine cells and glia was 17.63%. The spatial density of ganglion cells was lowest (1900-2500 cells/mm) in the ventronasal periphery. It increased centripetally to form a horizontal visual streak situated dorsal to the optic disc. The peak spatial density values (11,900-15,400 cells/mm) were registered in the dorsotemporal quadrant where a prominent area temporalis was found. The presence of area temporalis and visual streak is in line with the species' biology. |
