Thanks for this reference. I may also refer you to our article in which we
applied source based connectivity and showed this based on granger causality
and pdc calculations:

We wrote a commentary on a related topic a while ago:

http://journal.frontiersin.org/article/10.3389/fncom.2016.00121/full

Here, the original authors claimed that ICA destroys phase information and
therefore connectivity measures should be computed on raw scalp EEG
channels. There seems to be a basic misunderstanding what EEG is and what
channels actually measure.
