题目：Distinguishing roles of DmPFC and rTPJ on altruism enhancement in situations of inequality: A tDCS Study
The right temporo-parietal junction (rTPJ) and dorsomedial prefrontal cortex (DmPFC), engaging in social cognition, have been proposed to play key roles in guiding human altruistic behavior. However, no study has provided causal evidences in distinguishing the difference between rTPJ and dmPFC in altruism in situations of inequality. A total of 89 healthy young adults were randomly assigned to receive anodal transcranial direct current stimulation (tDCS) on either DmPFC or rTPJ. Stimulation on DmPFC increased subjects’ altruism by choosing disadvantageous-inequity options, but not rTPJ. It may be driven by perspective taking, instead of changes on selfishness or empathy. The results demonstrate that noninvasive interventions over DmPFC can enhance altruism in disadvantageous situations and concur with the theories proposing that DmFPC has evolved mechanisms dedicated to social cognition.
