Human discrimination and modeling of high-frequency complex tones shed light on the neural codes for pitch

Comparison of excitation patterns at low and high frequencies for the DBL stimulus.
Excitation patterns (average firing rate versus CF) for simulated high-spontaneous-rate and low-spontaneous-rate auditory-nerve fibers [52] responding to the low-frequency DBL stimulus (left column) and the high-frequency DBL stimulus (right column) in Experiment 2. The solid curve indicates the average excitation pattern while the filled area around the curve indicates ±1 standard deviation (over 10 simulations with different samples of masking noise and level roving). Vertical dashed lines indicate the frequencies of target components and masker components. Color of the lines indicates which F0 they corresponding to (orange for the lower masker F0, gold for the target F0, and pink for the upper masker F0). See Materials and Methods for more details on the simulations.
