The main facial nucleus of a marsupial, the North American opossum (Didelphis marsupialis virginiana), was subdivided into 6 portions by localizing HRP-positive neurons after injecting all muscles by each major peripheral motor branch of the facial nerve. In the medial lobe of this dumbbell-shaped nucleus the caudal auricular nerve, rostral auricular ramus and cervical ramus were represented dorsomedially, dorsolaterally and ventrally, respectively. The lateral lobe contained zygomatic ramus cells dorsomedially, marginal mandibular ramus cells ventromedially and buccal rami cells laterally. The cells supplying the caudal digastric muscle were in the accessory facial nucleus. Thus, even though the facial nucleus of the opossum lacks distinct ramal subdivisions in Nissl preparations, such are evident after HRP labeling.
通过向北美负鼠（弗吉尼亚负鼠，Didelphis marsupialis virginiana）面神经的各主要外周运动分支支配的所有肌肉注射辣根过氧化物酶（HRP）后定位HRP阳性神经元，将有袋动物的主要面神经核分为6个部分。在这个哑铃形核的内侧叶，耳后神经、耳前支和颈支分别在背内侧、背外侧和腹侧有对应的代表区。外侧叶背内侧有颧支细胞，腹内侧有下颌缘支细胞，外侧有颊支细胞。支配二腹肌后腹的细胞位于副面神经核。因此，尽管在尼氏染色标本中负鼠的面神经核缺乏明显的分支细分，但在HRP标记后这些细分是明显的。
