All coordinates [x,y,z in mm] are in MNI space. Second level contrasts are in italic type face.
rACC – rostral anterior cingulate cortex; DLPFC – dorsolateral prefrontal cortex; SII – secondary somatosensory cortex; dACC – dorsal anterior cingulate cortex.
All activations p < 0.001, uncorrected, are from our volumes of interest;
p < 0.05 corrected.
