The distribution and peripheral connections of aberrant ganglion cells in the facial nerve trunk of the cat were studied by means of Klüver-Barrera staining and retrograde transport of horseradish peroxidase (HRP). By the Klüver-Barrera staining, aberrant ganglion cells were observed in the facial nerve trunk between the geniculate ganglion and the junction of the auricular branch of the vagus with the facial nerve trunk, although the number varied considerably with each animal. These cells were generally medium-sized and of round or oval shape, with densely stained Nissl substance, the features of which were essentially similar to those of the geniculate ganglion. In cases where HRP injections were made into the anterior wall of the auricle, several HRP-labeled cells were found ipsilaterally in the facial nerve trunk in addition to cell labeling of the geniculate ganglion. The present study in the cat demonstrated that at least some of the aberrant ganglion cells scattered in the facial nerve trunk are parental to the axons to the auricle, subserving the cutaneous sensory function.
采用克吕弗-巴雷拉染色法和辣根过氧化物酶（HRP）逆行运输法，研究了猫面神经干中异常神经节细胞的分布及外周连接。通过克吕弗-巴雷拉染色，在膝状神经节与迷走神经耳支与面神经干交界处之间的面神经干中观察到异常神经节细胞，不过每只动物的细胞数量差异很大。这些细胞一般为中等大小，呈圆形或椭圆形，尼氏体染色浓密，其特征与膝状神经节基本相似。在将HRP注射到耳廓前壁的情况下，除了膝状神经节的细胞标记外，还在面神经干同侧发现了几个HRP标记的细胞。目前对猫的研究表明，散在于面神经干中的至少一些异常神经节细胞是支配耳廓轴突的亲代细胞，发挥皮肤感觉功能。
