^aPearson correlations showing no significant relationship between functional connectivity effects (mean Fz connectivity values) and measures of head movement (% BOLD frames scrubbed per subject) and SNR. Combined rs-fcMRI effects, linear combination of connectivity values from the thalamus and hippocampus to the two ROIs (ROIa and ROIb) derived from the Type I error-protected Group × Seed interaction analysis (see Whole-brain seed-based functional connectivity analyses). The linear combination was obtained as follows: [thalamus-to-ROIa + hippocampus-to-ROIb] − [thalamus-to-ROIb + hippocampus-to-ROIa]. Connectivity between each seed and ROI (e.g. thalamus-to-ROIa) was also individually tested for correlation with motion and SNR.
