RestingStatefMRI
Resting-state functional magnetic resonance imaging (rs-fMRI) is a neuroimaging technique that measures spontaneous fluctuations in the BOLD signal when the subject is at rest and not engaged in a specific task. It is used to study functional connectivity, defined as the statistical dependence between distant brain regions.
During rs-fMRI, participants lie still in the scanner, often with eyes closed or fixated, while blood-oxygenation
Analytical approaches include seed-based correlation, where a region of interest is correlated with the rest of
Prominent resting-state networks include the default mode network, salience network, and frontoparietal, sensorimotor, and visual networks.
Limitations include sensitivity to head motion and physiological noise, variability in scan parameters and preprocessing, and
