Reduction of motion-related artifacts in resting state fMRI using aCompCor
2014
NeuroImage
Preserved Fulltext
Recent studies have illustrated that motion-related artifacts remain in resting-state fMRI (rs-fMRI) data even after common corrective processing procedures have been applied, but the extent to which head ...
While scrubbing further attenuates motion-related artifacts when mean signals are used, scrubbing provides no additional benefit in terms of motion artifact reduction or connectivity specificity when using ...
