Quantitative perceived depth from sequential monocular decamouflage.

abstract：:Quantitative light microscopic techniques have been applied to photoreceptors, ganglion cells and dopaminergic amacrine cells in the retina of the North American opossum Didelphis virginiana. This marsupial has a retina with a central areal specialization where ganglion cells reach a maximum density of 2900/mm2 and co...
