Frequency-following responses, with latencies circa 6 msec, were recorded from five normal-hearing human subjects to brief 500 c/sec tone bursts presented monaurally. The frequency-following responses appear as peaks occurring at 2 msec intervals superimposed on a slow wave (pedestal-like) component. Comparisons were made between the frequency-following responses evoked by binaural and monaural stimuli. The results show that the binaural responses may be interpreted as the sum of two monaural responses. It is concluded, therefore, that there are two independent populations of neurons, each capable of generating a frequency-following response is not a microphonic-like response but rather that the individual waves in the frequency-following response are evoked by the collective activity of phase-locked single units. Finally, on the basis of the distinctness of the individual waves in the frequency-following response, it is concluded that the neural generators of the response must be spatially compact.
从五名听力正常的人类受试者单耳呈现短暂的500赫兹纯音脉冲时记录到了潜伏期约为6毫秒的频率跟随反应。频率跟随反应表现为以2毫秒间隔出现的峰值叠加在一个慢波（类似基座）成分上。对双耳和单耳刺激诱发的频率跟随反应进行了比较。结果表明，双耳反应可解释为两个单耳反应之和。因此得出结论，存在两个独立的神经元群体，每个群体都能够产生频率跟随反应，这不是一种类似微音器电位的反应，而是频率跟随反应中的各个波是由锁相单个单元的集体活动诱发的。最后，基于频率跟随反应中各个波的独特性，得出反应的神经发生器在空间上一定是紧凑的结论。
