Table 3. Significant Clusters in Statistical Analyses.
The table displays anatomical regions (Talairach atlas), Brodmann Areas, and Montreal Neurological Imaging (x, y, z) coordinates, as well as cluster size (k) and peak activation (tpeak). (a) Paired t-test (fasting > fed) for right and left caudate seed regions. (b) Regression of seed regions (right caudate, left caudate) and eigenvector centrality (EVC) on insulin sensitivity (SI) covarying for body mass index. (c) Regression of dorsal anterior cingulate cluster connectivity on SI during fasting and fed states.
