Retinal ganglion cell topography and spatial resolving power in the white rhinoceros (Ceratotherium simum).


PMID 27804143

Abstract

This study sought to determine whether the retinal organization of the white rhinoceros (Ceratotherium simum), a large African herbivore with lips specialized for grazing in open savannahs, relates to its foraging ecology and habitat. Using stereology and retinal wholemounts, we estimated a total of 353,000 retinal ganglion cells. Their density distribution reveals an unusual topographic organization of a temporal (2,000 cells/mm
