Spatial distributions of the vestibular nerve fibers from end organs to the vestibular ganglion (VG) were studied using physiological and anatomical methods. Physiologically, ampullary nerve compound action potentials (AP) were recorded from VG. Anatomically, HRP (horseradish peroxidase) was injected into the cut end of the ampullary nerve, and the stained neural elements were counted on serial sections. Nerve fibers from the anterior semicircular canal (SC) were distributed in the anterior half of the VG. The horizontal SC nerves were also distributed in the anterior half of the VG, but tended to be posterior. The posterior SC nerves were found predominantly in the posterior half and the antero-dorsal portions of the VG. These distribution patterns corresponded well to those confirmed by recording of AP. Furthermore, neural connections were found between the superior and the inferior vestibular nerves, suggesting receptor-receptor fibers. The majority of these fibers were small in diameter.
运用生理学和解剖学方法研究了从前庭终器到前庭神经节（VG）的前庭神经纤维的空间分布。在生理学上，从前庭神经节记录壶腹神经复合动作电位（AP）。在解剖学上，将辣根过氧化物酶（HRP）注入壶腹神经的切断端，并在连续切片上对染色的神经元进行计数。来自前半规管（SC）的神经纤维分布在前庭神经节的前半部分。水平半规管神经也分布在前庭神经节的前半部分，但倾向于靠后。后半规管神经主要分布在前庭神经节的后半部分和前背部分。这些分布模式与通过动作电位记录所证实的模式非常吻合。此外，在前庭上下神经之间发现了神经连接，提示存在感受器 - 感受器纤维。这些纤维大多数直径较小。
