title: [Morphology of the giant nerve cells in the bovine retina. Study of silver-impregnated total specimen].
abstract: Application of several silver impregnation methods on whole mounts of the bovine retina selectively elicits the giant ganglion cells of the peripheral retina. As determined by the branching pattern of their dendrites they coudl be classified in three types: 1. predominant branching in one directions; 2. branching in two opposite direction; 2. branching in two opposite directions; 3. branches radiate in all directions. Cells of the first type were mainly found in the temporal and dorsal (superior) segment; those of the second type in the nasal part; those of the third type were present in the ventral (inferior) part of the peripheral retina. The sizes of their dendritic fields differ. Another ganglion cell with a large perikaryon was found infrequently in each retina; its dendrites are located in the inner plexiform layer, ending with occasionally large knob- or clubshaped tips. An axon was never found. Evidently, they show a special topographical relationship to the blood vessels. Their function is as yet unknown.
