Abstract

The distribution and morphology of the retinal ganglion cells was studied in a relative of the rabbit, the Afghan pika. The total number of retinal ganglion cells was approximately 170,000. The total number of optic nerve fibers was between 160,000 and 190,000, corresponding to the total number of retinal ganglion cells. Retinal ganglion cells were found to have a horizontal region of high-density. The maximum density was 5250 cells/mm2. This region was located in the central retina below the optic disc. This area contained numerous closely packed small ganglion cells, while the peripheral retina (especially in the dorsal periphery) contained large ganglion cells more loosely dispersed. The retinal ganglion cells labeled by horseradish peroxidase (HRP) were morphologically classified into three types based on dendritic length and ramification pattern.

摘要

在兔的近亲阿富汗鼠兔中研究了视网膜神经节细胞的分布和形态。视网膜神经节细胞的总数约为170,000个。视神经纤维的总数在160,000至190,000之间，与视网膜神经节细胞的总数相对应。发现视网膜神经节细胞有一个高密度的水平区域。最大密度为5250个细胞/mm²。该区域位于视盘下方的视网膜中央。该区域包含许多紧密排列的小神经节细胞，而周边视网膜（尤其是背侧周边）包含分布较松散的大神经节细胞。根据树突长度和分支模式，用辣根过氧化物酶（HRP）标记的视网膜神经节细胞在形态上分为三种类型。
