Structural neuroimaging analyses revealed the neuroanatomical regions that had a positive association with AUs 4 and 6/7 and AUs 9 and 10 in the disgust trial and AUs 12 and 6/7 in the amusement trial (controlling for age, sex, and total intracranial volume). MNI coordinates given for the maximum T-score for each cluster (P < .005, uncorrected, k > 10).
