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.
