FIG. 1.

Connectivity matrix for Study 1, showing t-statistics for iFC in lower triangle in (A) (p < 0.05, uncorrected, denoted by cyan asterisks), and for SD-iFC in upper triangle in (A) (p < 0.05, uncorrected, denoted by yellow asterisks). Black asterisks indicate ROI pairs that exhibited significant differences in both iFC and SD-iFC. (B) Scatterplot showing relation between the computed t-statistics (for iFC and SD-iFC) across all ROI pairs in the matrices above. The x-axis corresponds to the t-statistics for iFC shown in the lower triangle, while the y-axis corresponds to the t-statistics for SD-iFC shown in the upper triangle. Green vertical line and blue horizontal lines show the threshold for significance. Cyan circled points show ROI pairs with a significant difference only in iFC, yellow circled points indicate those with a significant difference only in SD-iFC (indicated by yellow asterisks), and black circled points are ROI pairs that exhibited significant differences in both iFC and SD-iFC [indicated by black asterisks in (A)]. iFC, intrinsic functional connectivity; ROIs, regions of interest.
