Distributions of peak (top) and trough (bottom) modulation frequencies of band-enhanced (top) and band-suppressed inferior colliculus neurons (bottom), respectively, obtained with 3 types of envelopes and defined with a 1.2 criterion. No. of neurons for each panel is given in Fig. 9 legend. Median peak modulation frequency was 32 Hz for raised-sine-1 (RS1) envelope and 64 Hz for raised-sine-8 (RS8) and raised-sine-32 (RS32) envelopes. Median trough modulation frequency was 64 Hz for all 3 envelopes.
