In rat and guinea pig, cochlear efferents to the two ears were labeled simultaneously with different fluorescent tracers. It was found that in both species only few (1-3%) olivo-cochlear neurons were double-labeled and project to both cochleae. In most periolivary regions large olivocochlear neurons (OCN) projecting to the ipsilateral and contralateral side are intermingled and form a continuous cell column between the facial nucleus and lateral lemniscus. In a second series of experiments in rat, cochlear efferents and ascending olivo-collicular neurons were labeled. Olivo-cochlear and olivo-collicular neurons are intermingled in the lateral superior olive (LSO) and in the ventromedial periolivary region. No double-labeled neurons were found that project to the cochlea and the inferior colliculus.
在大鼠和豚鼠中，用不同的荧光示踪剂同时标记了双侧耳蜗传出神经。结果发现，在这两个物种中，只有少数（1 - 3%）橄榄耳蜗神经元被双重标记并投射到双侧耳蜗。在大多数橄榄周区域，投射到同侧和对侧的大型橄榄耳蜗神经元（OCN）相互交织，在面神经核和外侧丘系之间形成一个连续的细胞柱。在大鼠的第二组实验中，标记了耳蜗传出神经和上行橄榄丘神经元。橄榄耳蜗神经元和橄榄丘神经元在外侧上橄榄核（LSO）和腹内侧橄榄周区域相互交织。未发现投射到耳蜗和下丘的双重标记神经元。
