Neural activity in relation to temporal distance: Differences in past and future temporal discounting

► Neural activity in past temporal discounting differed in delay paradigms. ► The peak amplitudes of P2 and P3 varied with the past temporal distance. ► No significant differences were found between past 5 years and 50 years. ► Neural activity in future temporal discounting differed in interval paradigms. ► Conditions (6 months:5 years) and (6 months:50 years) had influence on P2 and N2.
