Ghrelin analyses. A, Mean decrease in plasma concentrations of total ghrelin at t = 30, t = 60, and t = 90 min after lunch onset at sated scan. Predicted correlations (ROI analysis) between extent of postprandial ghrelin suppression at t = 90 min after lunch onset at sated session and brain response to M > T at sated scan in BLA cluster with peak at x, y, z = −24, −7, −11 (B; R BLA cluster NS), and CMA clusters with peaks at x, y, z = −27, −10, −11 and x, y, z = 27, −10, −11 (C). Scatterplots show the relationship between postprandial ghrelin change at t = 90 min after lunch and parameter estimates at the peak voxel in that region. Color bars depict t-values.
