English: A significant positive correlation between GM and social status—dominance—is found in the AMY, PH, and adjacent lateral hypothalamus and RN and adjacent reticular formation. The determinant of the Jacobian matrix summarizes the size of the GM effect. For illustration purposes, partial correlations between the determinants of the Jacobian for each animal and for each ROI and dominance, after controlling for age, weight, sex, and number of structural scans, are shown. Spatially uncorrected effects (p<0.001, volume>1.25 mm3) are indicated by light (yellow) colors, whereas the darkest red color indicates effects at p<0.005 (cluster volume>5 mm3).
