Questions: What are the neural correlates of fairness?
What are the relative contributions of cognitive and emotional processes to economic decision-making?
Hypothesis: Decisions to either accept or reject unfair offers
will engage neural structures involved in both emotional and cognitive processing

Conclusion:
Emotional states are an important factor informing human decision-making.
Competition and interplay between the anterior insula and the DLPFC represent the twin demands of the Ultimatum Game:
The emotional resistance to unfairnessThe cognitive task of accumulating money
