The effects of motion correction strategies on the correlation between BOLD signal and voxel-specific head motion in the Cambridge dataset. The first column (“Raw”) demonstrated one-sample t-test on all the individual’s Fisher’s Z-score maps for the relationship between FDvox and BOLD signal obtained with the uncorrected data. Columns 2–4 demonstrated the motion-BOLD relationships after motion regression models (rigid-body 6, derivative 12, voxel-specific 12 and Friston 24). Row 2 demonstrated the motion-BOLD effects by combined scrubbing within the motion regression models (each bad time point defined a single regressor, i.e., spike regression). Row 3 demonstrated the results with scrubbing performed after the regression models (i.e., volume removing). To facilitate comparison with scrubbing strategies, 18 subjects that failed to meet the 3-minute criterion after scrubbing were removed, thus all the analyses here were based on the remaining 158 subjects.
