T-tests, degrees of freedom: 12 (placebo), 9 (DCS), 22 (placebo vs. DCS), statistical threshold P £ 0.001 uncorrected, one-tailed, unless indicated otherwise. Clusters <5 voxels not reported. ACC: anterior cingulate cortex, OFC: orbital frontal cortex, MNI: Montreal Neurological Institute, MPFC: medial prefrontal cortex, SCR: skin conductance response, SVC: small volume correction.
