Figure 1.

(Color online) (a) Illustration of experimental setup. (b) Evoked potential in response to alternating–polarity, 4 kHz stimuli presented at 40 dB SPL. CM amplitude was determined from the mean FFT amplitude (inset) at the stimulus frequency. The CAP (solid black line) was extracted by averaging the CM responses. CAP peaks N₁ and P₁ are shown.
