Also of importance is the investigation of the relationships between the functional connectivity as derived from fMRI data and from EEG/MEG data. Due to the different time scales and spatial resolutions of these two modalities there has not been a clearly established consistency between the results obtained from fMRI or EEG/MEG alone. Perhaps, this is simply owing to the fact that these modalities reflect the different and complementary consequences of the same neurophysiological origin. Combining both modalities promises to offer a more complete conclusion on the connectivity among assemblies of neurons.
