I have extracted the functional connectivity using the correlation method and shown them in graphs
How can I show these functional connectivity in a directional mode ??
There is no notion of directionality with the correlation measure.
Is it possible to show these direction of functional connections in other methods such as coherence and fuzzy lock?
Coherence has no concept of direction either.
I don't know what fuzzy lock is.
Granger causality provides measures with a direction.
