Six injections of HRP were placed in the periabducens reticular formation (PARF). Two were placed ventromedial to the caudal half of the abducens nucleus (VIn), two were placed further laterally and ventral to the rostral half of the nucleus, and two were placed rostral to the nucleus. Most injections in PARF produced cell labeling in the vestibular and perihypoglossal nuclei bilaterally and labeled cells in the reticularis gigantocellularis (Rgc) and reticularis pontis caudalis (Rpc) nuclei contralateral to the injection site. Few labeled neurons were found in the caudal part of the paramedian pontine reticular formation (PPRF). In the mesencephalon, bilateral but more numerous ipsilateral labeled cells were found in the medial mesodiencephalic region including the nuclei of Cajal, Darkschewitsch and the posterior commissure. Injections placed caudomedial to VIn resulted in a characteristic concentration of labeled cells in the ipsilateral nucleus cuneiformis and rostral half of the contralateral superior colliculus (SC). Injections placed rostral to VIn in PARF produced cell labeling in the nucleus campi Foreli. The results are related to physiological evidence which suggests that PARF is an important premotor center for coordination of oculomotor, head and body movements.
将六次辣根过氧化物酶（HRP）注射到展神经周围网状结构（PARF）中。两次注射位于展神经核后半部的腹内侧（VIn），两次注射位于展神经核前半部外侧且更靠腹侧的位置，另外两次注射位于展神经核的前方。PARF中的大多数注射在双侧前庭核和舌下神经周核产生细胞标记，并在注射部位对侧的巨细胞网状核（Rgc）和脑桥尾侧网状核（Rpc）中标记细胞。在脑桥旁正中网状结构（PPRF）的尾部发现的标记神经元很少。在中脑，在内侧中脑区域包括 Cajal 核、Darkschewitsch 核和后连合中发现双侧但更多的同侧标记细胞。在展神经核后半部的尾内侧进行注射，导致同侧楔状核和对侧上丘（SC）前半部出现特征性的标记细胞集中。在展神经核前方的PARF中进行注射，在 Forel 野核中产生细胞标记。这些结果与生理学证据相关，该证据表明PARF是协调眼球运动、头部和身体运动的重要运动前中枢。
