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.
几种银浸染方法应用于牛视网膜整装片时,可选择性地显示周边视网膜的巨型神经节细胞。根据其树突的分支模式,可将它们分为三种类型:1. 主要向一个方向分支;2. 向两个相反方向分支;3. 分支向各个方向辐射。第一类细胞主要见于颞侧和背侧(上方)部分;第二类见于鼻侧部分;第三类存在于周边视网膜的腹侧(下方)部分。它们树突野的大小各不相同。在每个视网膜中还偶尔发现另一种具有大核周体的神经节细胞;其树突位于内网状层,末端偶尔有大的球状或棒状末梢。从未发现轴突。显然,它们与血管呈现出一种特殊的拓扑关系。其功能尚不清楚。
