I have a question regarding the connectivity on the source space.
I would like to compte different metrics of connectivity (mainly coherence and AEC), I have a question regarding the source reconstruction measure.
Since I wanted to compute the connectivity, should I employ the CSD, dSPM or sLoreta ?
If I corrected understand, dSpm and sLoreta are some ways to normalize the CSD, and this approach should not be employed for frequency representation.
In general it is better to measure the CSD for connectivity purpose ?
