Brain areas tracking ESV. Brain areas in which the BOLD signal was correlated with the ESV for money (A) and food (B) in a random-effects group analysis (p < 0.0005 per voxel; p < 0.05 corrected for cluster size). A, Activities in subregions of the vmPFC (top), striatum (middle), and PCC (bottom) were correlated with the ESV for money. B, Activities in subregions of the vmPFC (top), striatum (middle), and hypothalamic region (bottom) were correlated with the ESV for food. C–E, Regression coefficients in the vmPFC, striatum, PCC, and hypothalamic region for money and food ESVs using a leave-one-out cross-validation method. The functional maps are overlaid on the mean normalized anatomical image. Sagittal (left) and coronal (right) slices are shown. X, Y, and Z coordinates are in Talairach space. R, Right; P, posterior; n, number of subjects. Error bars represent SEM. *p < 0.05 (t test between money and food betas).
