Frequency-dependent functional connectivity within resting-state networks: An atlas-based MEG beamformer solution

► Introducing a framework for reliable estimation of interactions in anatomical space. ► Choice of connectivity estimator (PLI) removes biases caused by volume conduction. ► Use of atlas-based ROIs aides interpretation and comparison with other modalities. ► Cortical profiles of resting-state power and connectivity are frequency-specific. ► Highly active brain regions are also the ones that are most-densely connected.
