     View Summary

    The current study aimed to elucidate neural mechanisms underlying formation of impulsivity and self-control in intetemporal choice behavior. During fMRI scanning, human participants performed an intertemporal choice task in which they first directly experienced delayed liquid rewards, followed by free choice trials. Formation of self-control was associated with temporal dynamics of anticipatory utility in the anterior prefrontal cortex (aPFC) during delay period, whereas that of impulsivity was associated with reverse dynamics in ventral striatum (VS). During consumption of delayed rewards, impulsive individuals showed greater activity in aPFC and VS and stronger functional connectivity from aPFC to VS. On the other hand, difficulty in decision-making was associated with prefrontal control mechanisms during choice.
