Responses of a chopper unit to a short tone (25 ms, 50 dB SPL), long tones (250 ms), noise alone (250 ms), or tones plus noise (250 ms). A: PSTH for responses to the short tone at CF. Bin width = 0.5 ms. B–I: tone-in-noise responses. B: PSTH for noise at 30 dB SPL spectrum level. Bin width = 2 ms. C: PSTH for noise in B plus a 65 dB SPL tone. Bin width = 2 ms. D: masked rate-level functions for a 250-ms CF tone and for tone plus noise. E: temporal correlation measured with different temporal-analysis windows. F: temporal reliability measured with different termoral-analysis windows. G: synchronization coefficent to tone. H: PSTH fluctuation measured with different temporal-analysis windows. I: rate-level function of SFIE model. All filled squares indicate significant increase, and all open squares indicate significant decreases (P < 0.05 or d′ ≥ 1). X on the abscissa indicates reponses to noise alone. G309u9: CF = 492 Hz, SR = 0 sp/s. Pure-tone rate threshold in quiet = 22 dB SPL (same neuron as in Fig. 1). Fifty trials per stimulus condition. Error bars are SD.
