Summary of the brain activations (bold) and deactivations (italic) identified in the regions of interest selected for the small volume correction (SVC) analysis using the SPM (statistical parametric mapping) software (t > 3.14; P < 0.01 uncorrected) and for the following contrasts: OS+DS+ (oral and duodenal sucrose stimulation), OS+DS- (oral sucrose stimulation only), and OS-DS+ (duodenal sucrose stimulation only) respectively, vs. control.
