| Abstract(in English) | In daily life, we often experience a conflict between the immediate and future outcomes of an action. Inability to resolve such conflicts is a hallmark of many psychiatric dysfunctions. In this study, we investigate whether different networks are specialized for the prediction of future and immediate rewards. Using functional MRI, we measured human brain activities of healthy subjects performing Markov decision problems which required prediction of both immediate and future rewards. In prediction of immediate reward, significant activities were observed in orbitofrantal cortex(OFC), anterior cingulate cortex(ACC), basal ganglia. In prediction of future reward, significant activities were observed in dorsolateral prefrontal cortex(DLPFC), ACC, basal ganglia, and celebellum. These results implicate that different networks exist for the prediction of future reward and immediate reward. |
