Results for the frequency-specific PPI effects for the observed significant clusters for the whole-brain alpha power PPI analysis. (A–D) For each cluster, the parameter estimates for the high and low alpha condition for frequencies between 2.5 and 27.5 Hz are shown. (E–H) The differences between the two conditions are shown. The shaded area indicates this difference deviates significantly from zero after multiple comparisons correction. For all panels, error bars indicate the standard error of the mean. Indicated p-values are corrected for multiple comparisons using a nonparametric cluster-based correction method. Note that the values in (A–D) are mirrored around the mean-level connectivity the different regions have with the seed. This is caused by the fact that the same seed signal segments are sorted into high- and low-power categories for each separate frequency bin.
