Dear SPM experts,
I want to perform a correct functional connectivity analysis and I am
looking for regions having a similar hemodynamic response function as my
defined regions of interest.
I have extracted timecourses of 10 different ROIs via the VOI function
in SPM99 of a single subject.
fMRI data were proportionally scaled and the extracted timecourses were
adjusted to any effects of interests.
Now I want to include the timecourses into the same design matrix.
Is it appropriate to put 10 timecourses simultaneous as regressors in a
design matrix for a single subject or should I put every single
timecourse in a seperate design matrix?
Thanks in advance
