Single unit recordings were made from the nerve branch innervating the crista in the horizontal semicircular canal of a pigeon. The vestibular organ was either stimulated with sound through the ear canal or with a vibrator in contact with the membraneous ampulla roof. Units responding to sound or vibration showed tuning with a best frequency of approximately 0.7 kHz. The average low-frequency slope of the tuning curves is--16 dB/oct; the average high-frequency slope 20 dB/oct. The threshold amplitude for vibrator stimulation is 30 nm. This value comes close to the calculated threshold value for cupula deflection in the human semicircular canal.
在鸽子水平半规管中，对支配嵴顶的神经分支进行了单单位记录。通过耳道用声音刺激前庭器官，或用振动器接触膜壶腹顶部进行刺激。对声音或振动有反应的单位表现出调谐，最佳频率约为0.7kHz。调谐曲线的平均低频斜率为-16dB/倍频程；平均高频斜率为20dB/倍频程。振动器刺激的阈值幅度为30nm。该值接近人类半规管中壶腹嵴偏移的计算阈值。
