DDT-related brain regions defined by task-related activations. a, Brain regions related to the valuation process. The money network consisted of brain regions in which the activity was positively correlated with monetary magnitudes of future reward; the time network consisted of brain regions in which the activity was negatively correlated with time delays of future reward. b, Brain regions related with the choice process. These were defied by contrasting hard versus easy trials in the DDT and were further divided into the frontoparietal network and the dACC–AIC network for their different functional roles in decision-making. Str, Striatum; Hip, hippocampus; paraHip, parahippocampus; MFG, middle frontal gyrus.
