EEG-based connectivity measures may provide two important extensions to this work: (1) they can reveal how the strength, spatial organization and spectral properties of connectivity among brain systems converge and diverge over time, and (2) they can capture these changes on a millisecond timescale. If beta-band synchronization is implicated in maintaining cognitive states (particularly the default mode), then one might expect that excessive beta-band connectivity would be associated with reductions in dynamic functional connectivity in the DMN.
