Auditory steady-state response (ASSR) results. A: single-subject data, indicating signal-to-noise ratio of the 41-Hz ASSR and the 1st 3 harmonics (82, 123, and 164 Hz), are displayed for channel Fz. Nonsignificant (n.s.) responses were set to 0 dB; note that only 1 participant had a nonsignificant ASSR: subject 16 at 82 Hz. B: group-average raw ASSR magnitude and the signal-to-noise ratio, along with the noise floor estimate, are depicted; these responses were created by averaging data in the frequency domain. Additionally, the raw magnitude computed by averaging data in the time domain before converting to the frequency domain is plotted. Below are the group-average scalp topographies of the raw ASSR magnitude (averaged in the frequency domain) at the 4 frequencies of interest.
