Note: One-sample t test, FWE corrected, p < .001, cluster size ≥6 voxels. Coordinates are given in the left-posterior-inferior system in the Montreal Neurological Institute (MNI) brain template space. L = left; R = right. DLPFC = dorsolateral prefrontal cortex; FWE = family-wise error; OFC = orbitofrontal cortex; POC = primary olfactory cortex. med = medial; mid = middle; sup = superior. corr = corrected; uncorr = uncorrected.
