对刺激频率和现有耳间强度差异的了解不足以预测S段细胞放电率。刺激水平，重新阈值，双耳传递的音调也必须知道。在低刺激水平下，最活跃的S段细胞群由其CF被调谐到刺激音频率的细胞组成。当双耳分听传递的音调的刺激水平增加到阈值以上。具有未调谐到刺激频率的CF的细胞倾向于以比最初在低水平下响应的细胞更高的速率放电。刺激水平越高，最活跃的细胞群的CF与刺激之间的频率差异越大。因此，S段内最大活动的位点不仅取决于双耳传递的刺激音的频率，而且取决于其刺激水平。[研究部分由美国政府支持。S.公共卫生服务]。
Knowledge of the frequency of the stimulus and existing interaural intensity differences are inadequate for predicting S‐segment cell discharge rates. The stimulus level, re threshold, of dichotically delivered tones must also be known. At low stimulus levels, the most active population of S‐segment cells consists of cells whose CF's are tuned to the frequency of the stimulus tone. As stimulus levels of dichotically delivered tones increase above threshold. cells with CF's not tuned to the stimulus frequency tend to discharge at rates higher than those of the cells initially responsive at low levels. The higher the stimulus level the greater the discrepancy in frequency between the CF's of the most active cell population and the stimulus. Thus, the locus of maximum activity within the S segment is dependent not only on the frequency of the dichotically delivered stimulus tone but also on its stimulus level.
