Placebo Analgesia Enhances Descending Pain-Related Effective Connectivity: A dynamic causal modeling study of endogenous pain modulation

The use of placebo to reduce pain is well documented; however, knowledge of the neural mechanisms underlying placebo analgesia (PA) remains incomplete. This study used fMRI data from 30 healthy subjects, and dynamic causal modeling (DCM) to investigate changes in effective connectivity associated wi...
