Dear SPM experts
My question is about what is the best way to build the first level
analysis for my data
I have for each patient 3 fMRI scans (one pre-intervention, and one in
immediate post intervention and the latest in late post-intervention)
As I want to find brain areas related to changes induced by the
intervention, is it better to construct the GLM with all the sessions
at once or to build one GLM for each session and then to look at the
difference at the second level?
I guess the results won t be the same, as the degree of freedom won't
be the same in the first level analysis?
Any advise would be helpful
Best
Charlotte
