Note: The table was obtained using whole-brain multilevel mediation analysis at onset of wine tasting in N = 30 subjects. Regions listed survived a whole-brain threshold of p < 0.001 uncorrected at the voxel level and small volume correction of pFWE < 0.05. BA: Brodmann area; vmPFC: ventromedial prefrontal cortex; PFC: prefrontal cortex.
