Following HRP (Horseradish Peroxidase) injections to cricothyroid muscle, recurrent laryngeal nerve and the vagal nerve at the level of nodose ganglion, labeled motoneurons were found to show a characteristic distribution in the brain stem of the monkey. Cricothyroid motoneurons extended from a level caudal to the facial nucleus to a level caudal to the middle part of the inferior olivary nucleus (IO) and were scattered around the outer area of nucleus ambiguus (Amb). Motoneurons supplying the recurrent laryngeal nerve were found between a level rostral to the middle of IO and its caudal end. Distribution was compact in the lateral part, but was scattered in the dorsomedial part of Amb. On injection of HRP into the nodose ganglion of the vagal nerve, labeled motoneurons were seen in two cell columns: In the Amb and in the dorsal motor nucleus of the vagus. The former extended from the rostral level of IO to the caudal end of IO, also showing connections with the retroambigual nucleus.
将辣根过氧化物酶（HRP）注射到猴的环甲肌、喉返神经以及结状神经节水平的迷走神经后，发现标记的运动神经元在猴脑干中呈现出特征性分布。环甲肌运动神经元从面神经核尾侧水平延伸至下橄榄核（IO）中部尾侧水平，散布于疑核（Amb）外侧区域周围。支配喉返神经的运动神经元位于IO中部头侧水平至其尾端之间。其分布在Amb外侧部密集，但在内背侧部较为分散。将HRP注射到迷走神经的结状神经节时，在两个细胞柱中可见标记的运动神经元：在Amb和迷走神经背运动核中。前者从IO头侧水平延伸至IO尾端，也显示与疑后核有联系。
