a Percentage of prosocial choices for friends minus disliked peers as a negative regressor in the whole-brain contrast Friend > Disliked Peer resulted in right anterior insula (36, 12, −6) and supplementary motor area (SMA) activation (−6, 15, 60). b Parameter estimates of the beta values of SMA and anterior insula from this contrast are plotted for percentage of prosocial choices for friends (left panel) and disliked peers (right panel) separately, showing that the negative relation between prosocial choices for friends minus disliked peers with SMA and anterior insula is driven by prosocial choices for friends.
