Abstract

The present study indicates that visual signals responsible for OKN are conducted through the retinal ganglion cells mainly contralaterally, and only in the ventral region of the retina ipsilateral to the injection site. The retinal ganglion cells projecting into the NOT ipsilateral to the injection site were identified as small- and medium-sized cells in the rat. The density of the ventral ganglion cells of the retina contralateral to the injection site was lower than that in any other regions of the retina except for the dorsal region of the retina, and the density of the ventral ganglion cells ipsilateral to the injection site was about 4 times greater than that on the contralateral side. This finding requires physiological investigation in the future.

摘要

本研究表明，负责视动性眼震（OKN）的视觉信号主要通过视网膜神经节细胞对侧传导，且仅在注射部位同侧视网膜的腹侧区域。投射到注射部位同侧视动性眼震区（NOT）的视网膜神经节细胞在大鼠中被鉴定为中小型细胞。注射部位对侧视网膜腹侧神经节细胞的密度低于视网膜除背侧区域外的任何其他区域，且注射部位同侧腹侧神经节细胞的密度约为对侧的4倍。这一发现有待未来进行生理学研究。
