Abstract

Retinofugal projections in the house musk shrew (Suncus murinus) were studied with the WGA-HRP method. After WGA-HRP injection into the vitreous cavity of one eye, terminal labeling was seen in the suprachiasmatic nucleus, dorsal and ventral lateral geniculate nuclei, pretectum and superficial layer of the superior colliculus. The terminal labeling in the suprachiasmatic nucleus was more marked on the side ipsilateral to the injection than on the contralateral side, whereas that in other regions was seen mainly on the contralateral side. A retino-intergeniculate leaflet projection was observed. No unequivocal terminal labeling was found in the lateroposterior thalamic nucleus.

摘要

采用WGA-HRP法研究了家麝鼩（Suncus murinus）的视网膜传出投射。将WGA-HRP注入一侧眼的玻璃体腔后，在视交叉上核、背侧和腹侧外侧膝状体核、顶盖前区和上丘表层可见终末标记。视交叉上核的终末标记在注射侧同侧比在对侧更明显，而其他区域的终末标记主要见于对侧。观察到视网膜-间膝小叶投射。在丘脑后外侧核未发现明确的终末标记。
