通过将辣根过氧化物酶应用于适当的颅神经，将提供内耳和侧线传出神经支配的神经元定位在脑中。传出神经元位于菱形脑核，这里称为octavolateralis传出核，位于内脏柱的吻极。这些神经元中多达40%是对侧的。传出细胞的位置与它们所支配的感觉器官在地形上没有关系。它们的轴突与面神经和舌咽神经中的其他运动轴突一起离开大脑，并且有证据表明一些神经元支配耳和侧线。传出核接受来自迷路的直接感觉输入，而不接受来自侧线的直接感觉输入，传出神经元的组织结构及其轴突的分布表明它们对感觉器官的作用可能是广泛的和非特异性的。
Neurons that provide the efferent innervation of the inner ear and lateral line were located in the brain by applying horseradish peroxidase to appropriate cranial nerves. The efferent neurons are found in a rhombencephalic nucleus, called here the octavolateralis efferent nucleus, which lies at the rostral pole of the visceromotor column. Up to 40% of these neurons are contralateral. The location of efferent cells is not topographically related to the sense organs they innervate. Their axons leave the brain together with other motor axons in the facial and glossopharyngeal nerves and there is evidence that some neurons innervate both the ear and the lateral line. The efferent nucleus receives direct sensory input from the labyrinth, but not from the lateral line.The organization of the efferent neurons and the distribution of their axons indicates that their effect on the sense organs is probably widespread and nonspecific.
