Resting-state fMRI is performed in the absence of specific cognitive tasks, where the baseline human brain activity is reflected in the spontaneous BOLD signal fluctuations. Conventional resting-state studies analysed signals below 0.1 Hz acquired by echo-planar imaging and assumed stationary networks during a scan session (typically between 5 and 15 minutes). In recent years time-frequency analysis of rs-fMRI data has been receiving growing interests, where high-temporal resolution imaging techniques are needed to enable the observation of brain networks in the additional temporal and spectral dimensions. Here we demonstrate that MR-Encephalography (MREG) is one of the fast-imaging techniques that are able to obtain a whole-brain volume image in less than one second. It enhances the detection of resting-state networks at individual subject level, which is crucial for dynamic functional connectivity analysis.
