Group differences in within- and between-network connectivity were examined by comparing lagged phase synchronization between all pairs of ROIs in the DMN and FPN at each frequency simultaneously. Analyses were first conducted using t-tests that were corrected for multiple comparisons using a non-parametric permutation procedure (5000 randomizations; see Supplement for additional details). To further probe group differences in connectivity, this was followed up using a less conservative approach where t values were thresholded at p<0.001 (uncorrected).
