All clusters were corrected for multiple comparisons with a cluster-forming threshold of p < 0.005 (uncorrected) and family–wise error (FWE) cluster correction at p <  0.05 using Monte-Carlo simulation in AFNI.

VS ventral striatum, DC dorsal caudate, DCP dorsal caudal putamen, VRP ventral rostral putamen, dlPFC dorsolateral prefrontal cortex, vlPFC ventrolateral prefrontal cortex, pgACC perigenual anterior cingulate cortex, OFC orbitofrontal cortex.
