Three combinations of MP/SP response patterns as functions of increasing bandwidth (MP, ■, SP, ○). The effect of increasing bandwidth on the MP response can be different from the effect on the SP response. ∗ indicates the minimum stimulus bandwidth for which the MP and SP responses significantly differ (t test, P < 0.05); the MP-SP difference is significant at all bandwidths at and beyond the ∗. Error bars indicate the SEM for each measurement. (A) At low bandwidths (≤2 kHz) the MP and SP responses are the same. However, beyond 2 kHz, where the MP and SP responses become statistically separable, the MP response remains constant, while the SP response declines. (B) Beyond 2.5 kHz the MP response continues to increase, while the SP response declines. (C) Up to 10 kHz, the MP response increases monotonically, while the SP response is essentially constant.
