The neural basis of functional connectivity in a semantic word processing task is examined, by comparing whole-brain connectivity matrices obtained from both MEG and fMRI data acquired in the same task and subjects. Novel methods are used for computing the connectivity in both modalities. Changes were observed between task vs rest as well as between task types in relevant brain areas and in multiple neural oscillatory frequency bands.
