Dear SPM expert's,
I ran a DCM analysis. I got a wining model for my B-matrix (using BMC) where tested the modulatory effects of 3 type of stimulation. I also defined a A-matrix considered as the baseline (using BMR).
If for example I got such result in my B-matrix for the posterior parameters values:
stimulus 1: ROI1 -> ROI2 (+0.23 Hz)
stimulus 2: ROI1 -> ROI2 (+0.05 Hz)
Can I said that the input from ROI1 to ROI2 is stronger in the condition with stimulus 1 (statistically)?
And can I also compare the the posterior parameters values from matrix-B to the one of matrix-A?
Many thanks in advance for any responses,
Best,
Carole
