Retinal ganglion cell topography in the masked greenling Hexagrammos octogrammus (Pallas, 1814) (Pisces, Scorpaeniformes, Hexagrammidae).
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/mm2) 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/mm2) 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.
期刊介绍：
The Journal of Fish Biology is a leading international journal for scientists engaged in all aspects of fishes and fisheries research, both fresh water and marine. The journal publishes high-quality papers relevant to the central theme of fish biology and aims to bring together under one cover an overall picture of the research in progress and to provide international communication among researchers in many disciplines with a common interest in the biology of fish.
