用辣根过氧化物酶对猫的单个听觉神经纤维进行细胞内标记。选择纤维样品以代表在宽范围的特征频率上的不同响应类型。所有56个标记的神经元都是支配内毛细胞的放射状纤维，这表明迄今为止报道的单单位数据都不是来自外毛细胞的神经支配。这些标记的神经元之间的自发放电率和阈值色调的差异密切相关的内毛细胞的身体上的无髓终末的口径和位置的形态差异。
Single auditory nerve fibers in the cat were labeled intracellularly with horseradish peroxidase. The sample of fibers was selected to represent different response types over a wide range of characteristic frequencies. All 56 labeled neurons were radial fibers innervating inner hair cells, suggesting that none of the single-unit data reported to date has been from the outer hair cell innervation. Differences in rates of spontaneous discharge and thresholds to tones among these labeled neurons were closely correlated with morphological differences in the caliber and location of their unmyelinated terminals on the body of the inner hair cell.
