Sub-region description	Power Reg	P-value a	Hyper/Hypo	Cohens-d
Left Cingulate/Temporal DMN	20	0.208	+	0.74
Left Frontal DMN *	13	0.037	+	1.34
Right Frontal DMN *	10	0.070	+	1.08
Right Frontal Task Control	9	0.070	+	1.06
Right Parietal Task Control	4	0.13	+	0.90
Right Ventral Temporal/Parietal Attention	5	0.208	+	0.71

Power Reg, Number of power regions in the sub-system; Hypo (-), hypoconnectivity; Hyper (+), hyperconnectivity; DMN, default mode network.

^a p values were false discovery rate (FDR) corrected.

* Time 1 also significantly elevated for cost in these regions; No Time 3 also significantly elevated for cost in these regions.
