| Abstract(in English) | Recent neurobiological research has demonstrated that the reward system in brain includes fundamental neural processes of value evaluation and preference formation. However, it remains unclear how the reward system in brain encodes reward value. In he present study, we investigated how the subjective value of faces is represented in brain while two faces were sequentially being presented by using fMRI. Dorsolateral prefrontal cortex (DLPFC) responded to a specific reward stimulus without dependence on pairing of another reward stimulus. In contrast, the activation of ventromedial prefrontal cortex (VMPFC) to an identical perceptual stimulus changes depending on the preceding context. The results suggested that neural representation of absolute and relative value of faces might be dissociable in the brain. Nucleus accumbens (NAC) and present study, suggesting that both signal might be integrated in these regions. |
