Sensory nerve fibers from the lateral line system and labyrinth of Anguilla anguilla were labeled with horseradish peroxidase and traced to various targets in the ipsilateral brainstem. The three rami of the anterior lateral line nerve and the supratemporal ramus of the posterior lateral line nerve form overlapping terminal zones in the ventral portion of nucleus medialis. The posterior lateral line nerve on the body is represented exclusively in the dorsal half of the nucleus medialis. Eighth nerve fibers from the otolithic end organs in the inner ear send fibers into dorsal portions of three octavus nuclei: anterior, magnocellular, and descending, and saccular fibers lie most medial and utricular fibers most lateral. Fibers from vestibular organs, especially the semicircular canals and utricle, end densely in ventral portions of these nuclei and in the tangential nucleus. All labyrinthine sense organs send fibers into the region of a Mauthner-like neuron, and all except the saccule terminate in the reticular formation, tangential nucleus, and eminentia granularis of the cerebellum. Primary sensory input to the octavolateralis efferent nucleus comes only from the labyrinth, and fibers from the saccule alone penetrate the region of efferent neuronal somata. Fibers from labyrinthine end organs except the saccule project to the reticular formation where they may contact the dendrites of efferent somata. Fibers from the lateral line and the eighth nerve overlap most extensively at the rostral pole of the nucleus medialis and in the eminentia granularis of the cerebellum.
用辣根过氧化物酶标记了欧洲鳗鲡侧线系统和内耳迷路的感觉神经纤维，并追踪到同侧脑干的各个靶点。前侧线神经的三个分支和后侧线神经的颞上分支在内侧核的腹侧部分形成重叠的终末区。身体上的后侧线神经仅在内侧核的背侧半部有代表。来自内耳耳石终器的第八神经纤维将纤维发送到三个听神经核的背侧部分：前核、大细胞核和降核，球囊纤维位于最内侧，椭圆囊纤维位于最外侧。来自前庭器官，尤其是半规管和椭圆囊的纤维密集地终止于这些核的腹侧部分和切线核。所有内耳迷路感觉器官都将纤维发送到类莫纳神经元的区域，除球囊外的所有器官都终止于网状结构、切线核和小脑颗粒隆起。八侧线传出核的初级感觉输入仅来自内耳迷路，仅球囊的纤维穿透传出神经元胞体区域。除球囊外，来自内耳迷路终器的纤维投射到网状结构，在那里它们可能接触传出神经元胞体的树突。侧线和第八神经的纤维在内侧核的吻端极和小脑颗粒隆起处重叠最广泛。
