Experiment 1. A: group-level analysis of intertrial phase coherence (ITPC) at auditory (left) and visual (right) electrodes in response to amplitude-modulated (AM) sounds relative to ITPC values in the prestimulus baseline period. Individual bars reflect auditory AM rate and matched analysis frequency. Center line indicates median; box limits, upper and lower quartiles; whiskers, 1.5 times interquartile range; points, outliers.*P < 0.05, **P < 0.005 (corrected for multiple comparisons). Error bars reflect SEM. B: group ITPC time-spectral plots for auditory (left) and visual (right) electrodes during a representative AM sound condition (40 Hz). Black polygon denotes p < 0.05 significance (corrected for multiple comparisons). Significant entrainment is present at 40 Hz only for auditory electrodes. C: auditory and visual electrodes from all patients showing either significant (red to white) or nonsignificant (black) ITPC values during the presentation of AM sounds relative to phase-shuffled data, reflecting neural entrainment to the auditory stimulus. Significant electrodes cluster around the central superior temporal gyrus, proximal to auditory cortex, and are noticeably absent from visual areas.
