This pattern is different from what we observed for the dorsal-anterior insula. We found that the right DLPFC showed the modulation effect, as evidenced by an increased activation when facing an unfair proposal with a high stake size, in which lower rejection rate was observed. All participants were in good health with no previous history of psychiatric or neurological disease and were screened for standard magnetic resonance safety criteria. Dissociable brain networks involved in development of fairness considerations: understanding intentionality behind unfairness. The other region that might be modulated is the insula. Implementation of this normative decision means that the responders succeed in curbing their self-interest goal, i. When we linked inter-individual differences in this behavioral modulation effect with brain activation, the left IFG was found to play a critical role in making the fairness-related normative decision in the social interaction condition. Player A the proposer makes a proposal about how to divide the money.
