Significant interactions of age × PSS × GDS on the DMN, during resting state (a) and task-induced deactivations (b). Each graphic line is the regression line between age and functional measures for: low PSS values (LPSS, black lines), combined with low GDS (LPSS-LGDS, solid line) or with high GDS (LPSS-HGDS, dotted line); and high PSS value (HPSS, red lines), combined with low GDS (HPSS-LGDS, solid line) or high GDS (HPSS-HGDS, dotted line)
