Following injections of horseradish peroxidase in the oculomotor and the trochlear nuclei in the hen, the occurrence of labeled cells was plotted in the vestibular nuclei. The majority of labeled cells was localized in the superior, the medial, and the tangential nucleus. Within the superior nucleus the cells were found mainly caudally, extending medially and ventrally in central areas. In the medial nucleus labeled cells were localized exclusively in its rostral half, mainly in ventrolateral regions. Most, if not all, cells in the nucleus tangentialis project rostrally. In addition, rostrally projecting vestibular cells were found in the cell group A and the rostrolateral part of the descending nucleus. The projection to the oculomotor nuclear complex is from the superior nucleus and the cell group A bilateral but chiefly ipsilateral, from the medial nucleus bilateral, from the tangential nucleus and the rostral pole of the descending nucleus chiefly contralateral. Massive labeling was found in the abducens nucleus, somewhat less in the reticular formation, mainly in the lateral regions of the medial part at the level of the abducens and facial nuclei. Labeled cells were, in addition, found in the deep layers of the optic tectum, and scattered cells in the nucleus raphe. The findings are discussed in the light of what is known of the organization of the vestibular nuclei in the hen and the rostral projection of the vestibular nuclei in mammals.
在母鸡的动眼神经核和滑车神经核注射辣根过氧化物酶后，绘制了前庭核中标记细胞的分布图。大多数标记细胞位于上核、内侧核和切向核。在上核内，细胞主要位于尾部，在中央区域向内侧和腹侧延伸。在内侧核中，标记细胞仅位于其吻侧半，主要在腹外侧区域。切向核中的大多数（如果不是全部）细胞向前投射。此外，在A细胞群和下行核的吻外侧部分发现了向前投射的前庭细胞。动眼神经核复合体的投射来自上核和A细胞群，双侧投射但主要是同侧投射；来自内侧核，双侧投射；来自切向核和下行核的吻极，主要是对侧投射。展神经核中发现大量标记，网状结构中的标记较少，主要位于展神经和面神经核水平的内侧部外侧区域。此外，在视顶盖深层发现了标记细胞，在中缝核中有散在细胞。根据已知的母鸡前庭核组织和哺乳动物前庭核的吻侧投射对这些发现进行了讨论。
