Figure B.1.

Waveform (T2_250) and spectrograms of each of the three stimulus conditions (T2_150; T2_200; T2_250) illustrate the experimental paradigm used to acquire cortical responses. The vertical dashed line at 493 ms demarcates the transition from the initial noise segment to the final pitch segment. FFRs and CPRs were extracted from evoked responses beginning with the onset of the pitch. F₀ contours (white) are superimposed on their respective pitch segments. Within the pitch segment, the waveform (top) shows robust periodicity at a high IRN iteration step (n=32); the spectrograms show clear resolution of dynamic, rising spectral bands corresponding to the harmonics of the fundamental frequency.
