Abstract

Wheat germ lectin-horseradish peroxidase was injected into the medial medullary reticular formation in 4 cats. Retrogradely labeled cell bodies were observed in the ipsilateral substantia nigra pars reticulata and bilaterally in the superior colliculus, oculomotor nucleus and fastigial nucleus of the cerebellum. The nigral projection to this reticular formation area, which receives diffuse afferents from cortex, cerebellum, oculomotor system and vestibular nucleus and projects to spinal cord, may be of some relevance in understanding the nigral role in postural, head- and eye-movement control.

摘要

将麦胚凝集素-辣根过氧化物酶注入4只猫的延髓内侧网状结构。在同侧黑质网状部以及双侧的上丘、动眼神经核和小脑顶核中观察到逆行标记的细胞体。该网状结构区域接受来自皮质、小脑、动眼系统和前庭核的弥散传入，并投射到脊髓，黑质向该区域的投射可能与理解黑质在姿势、头部和眼球运动控制中的作用有关。
