Note: Statistical significance was determined by a voxelwise p < .05, family-wise error corrected for multiple comparisons. Brodmann Area 25 (BA25); Inferior Orbitofrontal Cortex (infOFC); Medial Orbitofrontal Cortex (medOFC); Middle Orbitofrontal Cortex (midOFC); Superior Orbitofrontal Cortex (supOFC); Inferior Fronto-Occipital Fasciculus (IFO); Inferior Longitudinal Fasciculus (ILF); Uncinate Fasciculus (UF); Ventral Amygdalofugal Pathway (VAF). Peak voxel locations (X, Y, Z) are listed in MNI space.
