a Significant group differences in connectivity strength between FXS and healthy control participants based on permutation tests (p < 0.05) show increased connectivity in FXS in the gamma band across electrodes but reduced within-band connectivity in the alpha (lower and upper) and beta range. b Mean and standard error of between-electrode distances for electrode pairs showing group differences (plotted in a) in lower alpha, upper alpha, beta and gamma bands. Asterisk denotes significant differences in connectivity distances with significant group differences between bands at p < 0.05. c Bivariate scatter plots depicting the relationship between average connectivity strength (dbWPLI) and average between-electrode distance for FXS (red dots) and healthy control participants (black dots)
