The spatial distribution of nerve fibers from individual vestibular end organs in the vestibular ganglia (VG) was studied using horseradish peroxidase (HRP). HRP was injected into the cut end of the bull frog ampullary nerve. Stained neural elements were counted on the serial sections. Spatial distribution was also studied by recording ampullary nerve compound action potentials (AP) from VG. The anterior semicircular canal (SC) nerves were distributed in the anterior half of VG. The horizontal SC nerves were also distributed in the anterior half of VG, but tended to be posterior. The posterior SC nerves were found predominantly in the posterior half and antero-dorsal portions. These distribution patterns corresponded well with those confirmed by AP recording. There were a few neural connections between anterior and posterior SC, or horizontal and posterior SC, indicating receptor-receptor fibers.
利用辣根过氧化物酶（HRP）研究了前庭神经节（VG）中来自单个前庭终器的神经纤维的空间分布。将HRP注入牛蛙壶腹神经的切断端。在连续切片上对染色的神经元进行计数。还通过记录来自VG的壶腹神经复合动作电位（AP）来研究空间分布。前半规管（SC）神经分布在VG的前半部分。水平半规管神经也分布在VG的前半部分，但倾向于靠后。后半规管神经主要见于后半部分和前背部分。这些分布模式与通过AP记录所证实的模式非常吻合。在前半规管和后半规管之间，或水平半规管和后半规管之间存在一些神经连接，提示存在感受器 - 感受器纤维。
