Knowledge of the frequency of the stimulus and existing interaural intensity differences are inadequate for predictingS‐segment cell discharge rates. The stimulus level,rethreshold, of dichotically delivered tones must also be known. At low stimulus levels the most active population ofS‐segment cells consists of cells whose CFs are tuned to the frequency of the stimulus tone. As stimulus levels of dichotically delivered tones increase above threshold, cells with CFs not tuned to the stimulus frequency, tend to discharge at rates higher than these of the cells initially responsive at low levels. The higher the stimulus level, the greater the discrepancy in frequency between the CFs of the most active cell population and the stimulus. Thus, the locus of maximum activity within theS‐segment is dependent not only on the frequency of the dichotically delivered stimulus tone but also on its stimulus level.
