Idual decision models. Model parameters were generated by fitting sigmoid functions

The self ther contrast showed that activation in the right amygdala (x = 24, y = 0, z = -22) was closer to that predicted by the value computation model for self than that for other, while activation in the left DMPFC (x = -14, y = 32, z = 32) showed a stronger association with the decision model for other than for self (Figure 4).Parametric modulation analysis using expected value and http://www.tongji.org/members/tunewriter1/activity/238929/ outcomecorrelations between their activity levels and those of rTPJ were modulated by psychological condition (decision-for-self versus decision-for-other). The analyses revealed that the chance of making a risky choice for self was positively correlated with activation of the right anterior amygdala (x = 16, y = 6, z = -16), whereas the chance of making a risky choice for other was positively correlated with activation of the left DMPFC (x = -14, y = 34, z = 32). Activation was not negatively correlated with the chance of making a risky decision-for-self or for other in any brain region. To investigate which brain regions drive the differences between the models for self and other, we calculated the contrast between the value computation models for self and other via parametric modulation analysis. The self ther contrast showed that activation in the right amygdala (x = 24, y = 0, z = -22) was closer to that predicted by the value computation model for self than that for other, while activation in the left DMPFC (x = -14, y = 32, z = 32) showed a stronger association with the decision model for other than for self (Figure 4).Parametric modulation analysis using expected value and outcomecorrelations between their activity levels and those of rTPJ were modulated by psychological condition (decision-for-self versus decision-for-other). The results revealed that rTPJ showed stronger positive connectivity with the left DMPFC (x = -4, y = 34, z = 34) in the decision-for-other condition than the decision-for-self condition (p
