It
has been shown with resting-state fMRI that the Default Mode Network (DMN) is
anti-correlated with the Task Positive Network (TPN). In this study, we used
simultaneous EEG-fMRI to investigate
the relationship of the EEG alpha power time course with the resting-state BOLD signals in
these anti-correlated networks. We found that the relation between the EEG
alpha power and BOLD fMRI signals in these networks is stronger when using independent components (as
determined with Independent Components Analysis) as compared to the use of
the global alpha power.
