Dear SPM- and DCM-experts,
I want to specify a DCM model with a direct input pain and a modulatory input which is pain after having received medication. While building the DCM I wondered, does it make sense to modulate not only connections but also regions with “medication”? And moreover, does it make sense or is it necessary to modulate the self-connection of each region with “medication”?
Thank you for your help,
carmen
