Hi all,
Actually I am a new in using SPM specially DCM. I am wondering if there any training course for using DCM for EEG data. I have currently EEG data for epileptic patients and I would like to estimate effective connectivity between sources every one second. how could I do that?
should I use cross spectral density with LFP or use evoked response potential?
where I can find the matrix of effective connectivity is it in A or B.
about data and design matrix (contrast) how do I create it because all what I want to check effective connectivity between sources and I do not have any stimulus.
sorry for the long question
thank you
