Amethod of functional MRI that is used to measure brain functional organization.  This technique is often employed to measure neural interactions present when aparticipant is not performing an explicit task.  Resting-state encompasses manyphysiological and brain states, including naturally sleeping infants, fetusesin unconstrained states, unconscious individuals, and participants instructedto rest quietly but remain awake.  The latter is by far the most commoncondition for resting-state fMRI.
