The mu rhythm is a field oscillation in the ∼10Hz range over the sensorimotor cortex. For decades, the suppression of mu (event-related desynchronization) has been used to index movement planning, execution, and imagery. Recent work reports that non-motor processes, such as spatial attention and movement observation, also desynchronize mu, raising the possibility that the mu rhythm is associated with the activity of multiple brain regions and systems. In this study, we tested this hypothesis by recording simultaneous resting-state EEG-fMRI from healthy subjects. Independent component analysis (ICA) was applied to extract the mu components. The amplitude (power) fluctuations of mu were estimated as a time series using a moving-window approach, which, after convolving with a canonical hemodynamic response function (HRF), was correlated with blood-oxygen-level-dependent (BOLD) signals from the entire brain. Two main results were found. First, mu power was negatively correlated with BOLD from areas of the sensorimotor network, the attention control network, the putative mirror neuron system, and the network thought to support theory of mind. Second, mu power was positively correlated with BOLD from areas of the salience network, including anterior cingulate cortex and anterior insula. These results are consistent with the hypothesis that sensorimotor mu rhythm is associated with multiple brain regions and systems. They also suggest that caution should be exercised when attempting to interpret mu modulation in terms of a single brain network.

... While lower alpha is involved in internalized attention (Aftanas and Golocheikine, 2001), upper alpha is involved in specific cognitive tasks and memory processes (Klimesch et al., 1997). In this line and similar to our results, the alpha band also includes the mu rhythm (9 ± 2 Hz), which is typically observed in the centro-parietal regions and is particularly involved in motor function and the mirror neuron system (Yin et al., 2016). A specific association has been reported between the mu rhythm, the theory of mind and the SN regions (Mar, 2011;Schulte-Rüther et al., 2007;Yin et al., 2016), highlighting its involvement in the processing of emotional valence stimuli and social development (Vanderwert et al., 2013). ...
