Glass brain (A) and t-score map (B) of regional gray matter volume (GMV) positively associated with postprandial PYY concentrations. (C) t-score map of positive associations between regional GMV and PYY response.
Maps are thresholded at p<0.001 and a cluster size of 100 continuous voxels (glass brain only), uncorrected for multiple comparison; rACC right anterior cingulate, lGP left globus pallidus, lCN left caudate nucleus, rCN right caudate nucleus, lMTG left medial temporal gyrus, lFG left fusiform gyrus, rMTG right medial temporal gyrus;
(D) Correlation between gray matter (GM) values (adjusted for TIV) of the left and right caudate peak voxel with postprandial PYY values (adjusted for age, sex, PFAT).
