The origin of sympathetic fibers in the facial nerve of Macaca fuscata was demonstrated using the HRP method. WGA-HRP injection into the facial nerve resulted in heavy labeling in the ipsilateral superior cervical ganglion. The majority of labeled neurons in the superior cervical ganglion had sizes ranging from 20 to 35 microns. In the present study it was of particular interest that labeled neurons are also found in the intermediolateral nucleus and lateral funiculus ipsilaterally at the level from the C8 to T4 spinal cord segments. Many labeled neurons in the lateral funiculus were located in close vicinity to the intermediolateral nucleus, and, characteristically, a few of these had a long dendrite extending to the lateral surface of the spinal cord. The labeling in the spinal cord appears to be caused by transneuronal transport of WGA-HRP.
采用辣根过氧化物酶（HRP）法证实了猕猴面神经中交感纤维的起源。将小麦胚凝集素-辣根过氧化物酶（WGA-HRP）注入面神经后，同侧颈上神经节出现大量标记。颈上神经节中大多数标记神经元的大小在20至35微米之间。在本研究中，特别有趣的是，在同侧C8至T4脊髓节段水平的中间外侧核和外侧索中也发现了标记神经元。外侧索中的许多标记神经元位于靠近中间外侧核的位置，并且，其特征是其中一些有一条长树突延伸至脊髓外侧表面。脊髓中的标记似乎是由WGA-HRP的跨神经元运输引起的。
