Although not commonly adopted at present, "real-time" correction methods are emerging that can be combined with retrospective methods and that promise better correction and increased rs-fMRI signal sensitivity  ...  Despite this, rs-fMRI signals are easily contaminated by artifacts arising from movement of the head during data collection.  ...  In the case of task-based fMRI, head motion can be temporally correlated with task performance and under many circumstances, the resulting "motion artifacts" cannot be distinguished from brain activity  ...
