FIG. 1.

Frequency- and region-dependent correlations between head motion and rs-fMRI spectral power across all subjects (n=1000). Without GSR, greater head motion during rs-fMRI scanning was associated with lesser low-frequency power in MPFC and LTC (i.e., DMN) and greater low-frequency power in the pre- and postcentral gyrus (i.e., SMN), mid-cingulate cortex and insula (i.e., VAN); lesser mid-frequency power in the SMN and visual network; and greater high-frequency power in DMN and FPCN. With GSR, brain regions in DMN and FPCN similarly exhibited lesser low-frequency power and greater high-frequency power in subjects with greater head motion. Bar plots in the right column represent the network allocations and the number of voxels show significant correlations with head motion. White bars denote the number of voxels showing a negative correlation with head motion, while black bars denote the number of voxels showing a positive correlation with head motion [y axes of the bar plots scale from 0 to 8000 with a 2000 tick; Visual, visual network; GSR, global signal regression; rs-fMRI, resting-state functional magnetic resonance imaging; VAN, ventral attention network; SMN, somatomotor network; Limbic, limbic network; FPCN, frontoparietal control network; DMN, default mode network; and DAN, dorsal attention network; Network masks as provided by Yeo et al. (2011)].
