Parasympathetic motoneurones in the oculomotor complex which innervate the ciliary ganglion were identified using the horseradish peroxidase (HRP) retrograde axonal tracer technique. The ciliary ganglion was located behind the eye by a lateral orbital approach and injected with HRP pellets mounted on the tips of microelectrodes. Most of the labelled cells were distributed throughout the whole Edinger-Westphal nucleus (EW). Outside the EW, only a small number of labelled cells were found, and most of these were located in the median zone ventral to the EW. There was no evidence of a division of the EW into rostral and posterior subnuclei, nor for separate cell populations in the EW and the anterior median nucleus (AM), respectively. At rostral levels labelled cells were confined to the EW with no overlap into the AM. In contrast to most previous studies no labelled cells were found in the AM. The possible physiological functions of the EW and the ventral components of the EW are discussed.
运用辣根过氧化物酶（HRP）逆行轴突示踪技术，鉴定了动眼神经核复合体中支配睫状神经节的副交感运动神经元。通过外侧眶入路将睫状神经节定位在眼后，并用安装在微电极尖端的HRP微丸进行注射。大多数标记细胞分布于整个动眼神经副核（EW）。在EW之外，仅发现少量标记细胞，其中大多数位于EW腹侧的正中区域。没有证据表明EW分为吻侧和尾侧亚核，也没有证据表明EW和前正中核（AM）中分别存在独立的细胞群。在吻侧水平，标记细胞局限于EW，未与AM重叠。与大多数先前研究不同的是，在AM中未发现标记细胞。文中讨论了EW及其腹侧成分可能的生理功能。
