Austin Hughes (1977) analysed the topography of the retinal ganglion cells in various species of mammals with particular focus on their density, the density gradient towards the periphery, the presence or not of the visual streak and/or the area centralis, and he concluded that the differences in these parameters were closely related to the animal's lifestyle.
