The Best-Vision Zones and Visual Resolution of the Retina of Neonatal Bottlenose Dolphins Tursiops truncatus

The topography of ganglion cells in the retina of three neonatal bottlenose dolphins Tursiops truncatus has been studied in retinal wholemounts. Two areas of high ganglion cell density have been identified in the form of local spots in the temporal and nasal quadrants of the retina, near a horizontal diameter at a distance of 10–15 mm from the optical disk. The maximum density of ganglion cells in these areas on average for five preparations is...
