Supplemental Information

Full list of the 20 IC maps

The anterior DMN (A), posterior DMN (B), salience (C), dorsal attention (D), left executive (E), and right executive (F) components were used in the current PPI analysis. ICs G through J are categorized as unimodal networks, including the primary visual (G), higher visual (H), motor (I), and auditory (J) networks. ICs K and L are commonly identified components, however, their functions are not yet been clearly defined. We identified the remaining ICs (M through T) as noises, because their major clusters are located in either large blood vessels, ventricles, or eye balls. The IC maps were z transformed, and thresholded at z > 1.96.

Results of the network-wise PPI analysis

Numbers in each cell represent mean beta values and raw p values (in brackets) of corresponding cross subject one sample t-test. Bold font indicates statistically significant after Bonferroni multiple comparison correction of totally 60 correlations.

List of regions that showed significant PPI effects in voxel-wise analyses

Negative t values indicate negative PPI effects. Clusters were thresholded at p < 0.001, and cluster-level false discovery rate (FDR) correction was applied at p < 0.0033, which had taken into account of totally 15 voxel-wise analyses.
