Repetitive stimulation of the bullfrog glossopharyngeal nerve at a rate of 100 Hz for 10 s and at a supra-maximal intensity resulted in little depression of the glossopharyngeal nerve responses to application of quinine and mechanical taps to the tongue, in a 30-40% decrease in the responses to salt, acid, water and warmed saline and in a 80% decrease in the number of spontaneous discharges from the tongue. Such a selective depression existed throughout changes in the frequency and the duration of the antidromic stimuli. The phenomena were attributed to antidromic impulses in high-threshold glossopharyngeal nerve afferents.
以100赫兹的频率、超最大强度对牛蛙舌咽神经进行10秒的重复刺激，导致舌咽神经对奎宁和机械轻敲舌头的反应几乎没有抑制，对盐、酸、水和温热盐水的反应降低了30 - 40%，舌头自发放电数量减少了80%。在逆向刺激的频率和持续时间变化过程中，这种选择性抑制一直存在。这些现象归因于高阈值舌咽神经传入纤维中的逆向冲动。
