Abstract
⺠Large changes in rs-fcMRI timecourses coincide with motion despite motion regression. ⺠Motion increases short-distance correlations and decreases long-distance correlations. ⺠Motion artifacts do not arise from, and are not fully countered by, motion regressions. ⺠Framewise indices of data quality and methods to remove motion artifact are proposed.
