Although a variety of explanations have been suggested, the neural foundations of this effect have not been fully explored. Using a modified trust game, we find trustees reciprocate relatively less when facing sanction threats, and the presence of sanctions significantly reduces trustee’s brain activities involved in social reward valuation (VMPFC, LOFC, and Amygdala), while
