Phase-lagged connectivity in the three groups of participants: LR ( N = 26), HR-no-ASD ( N = 18), HR-ASD ( N = 10). (A) Global connectivity as a function of frequency. Black lines show group means with vertical bars denoting standard errors; red lines show group median values. Cyan bars mark 7–8 Hz alpha range. (B) Scalp distributions of alpha-range dbWPLI values averaged for each electrode across all its connections (115 for each electrode). (C) Group means (red lines) and variability of global alpha connectivity.
