The motoneurons of the oculomotor complex responsible for controlling accommodation and pupil size of the marmoset were identified by injecting horseradish peroxidase (HRP) into the ciliary ganglion. The anatomical organization of accommodation and pupil constrictor motoneurons was determined using electrical stimulation techniques. HRP-labelled cells were found through the whole length of the Edinger-Westphal nucleus (EW) and also just ventral to this nucleus in caudal sections. A projection from the antero-median nucleus to the ciliary ganglion could not be demonstrated. Electrical stimulation data showed that currents of less than 1 microampere applied inside the EW evoked accommodation responses. Pupil constriction responses, on the other hand, were evoked with weak currents at sites ventral to those in the EW generating accommodation at caudal and central levels. It was concluded that the EW was responsible for accommodation and areas containing HRP-labelled cells ventral to the caudal part of the EW were responsible for pupil constriction.
通过将辣根过氧化物酶（HRP）注入睫状神经节，确定了负责控制狨猴调节和瞳孔大小的动眼神经复合体运动神经元。使用电刺激技术确定了调节和瞳孔收缩运动神经元的解剖结构。在整个动眼神经副核（EW）全长以及尾侧切片中该核正腹侧均发现了HRP标记的细胞。未证实从前正中核到睫状神经节有投射。电刺激数据表明，在EW内部施加小于1微安的电流可诱发调节反应。另一方面，在尾侧和中央水平产生调节反应的EW腹侧部位，用弱电流可诱发瞳孔收缩反应。得出的结论是，EW负责调节，而EW尾侧部分腹侧含有HRP标记细胞的区域负责瞳孔收缩。
