Figure 2.

Brain activations, deactivations, and group differences during “Unfair > Fair” contrast. Note: (A) Top panel displays the brain regions showing activations and deactivations during “Unfair > Fair” offers in both groups. Warm colors reflect normal weight group and cold colors reflect excess weight group. (B) Bottom panel displays the differences between groups. Bottom‐right panel displays the correlations between “Unfair offers accepted” and peaks activation at dorsal ACC and anterior insula/frontal operculum in the “Unfair > Fair” comparison. X, Y and Z denote coordinate in standard MNI space. Right hemisphere is displayed on the right. Color bar indicates T value.
