Cross-frequency coupling between delta (1 Hz) and higher frequencies is strongly linked to perceptual outcomes. (A) Significant differences between delta-phase bins across electrodes and frequencies at the single-participant and population levels. A gray mask covers insignificant (corrected p-value ≥ 0.05) phase-detection relationships. (B) Corresponding scalp topographies are shown for the peak frequencies at the population level. Only electrodes with significant differences (corrected p-value < 0.05) in the phase-detection relationships between the delta-phase bins are plotted. The size and color of the electrodes represent the magnitude of the difference (in the phase-detection relationship) between the delta-phase bins.
