Scatter plots of the average inter-regional correlation versus the average root-mean-square (RMS) frame displacement for all subjects and sessions. The correlation was computed using (a) functionally connected voxels (r = −0.016, p = 0.908), and all voxels in each predefined ROI with a size of (b) 6 × 6 × 6 mm3 (r = 0.172, p = 0.214), (c) 10 × 10 × 10 mm3 (r = 0.154, p = 0.267), (d) 14 × 14 × 14 mm3 (r = 0.151, p = 0.276), and (e) 18 × 18 × 18 mm3 (r = 0.135, p = 0.332).
