Granger causality & EEG-EMG connectivity

Discussions
1

Hi Brainstorm team,

Is it possible to do spectral Granger causality for EEG-EMG connectivity in Brainstorm right now?
I have EEG & EMG data in a set file loaded into Brainstorm (96 EEG channels + 4 EMG channels, noted in the channel file), I just seem to have difficulty finding how to link the EEG with the EMG channels to compute GC.

Thank you!
Adam

Hi Adam,

Yes it is possible, check this tutorial, in which coherence between MEG and EMG is computed.
