| Outline of Final Research Achievements |
Human behaviors are influenced by not only rewards for oneself, but also rewards for others. To investigate neuronal mechanisms underlying reward processing in social contexts, we devised a social Pavlovian conditioning procedure for two monkeys facing each other and monitored single-unit activity in the medial prefrontal cortex (MPFC) and dopaminergic midbrain nuclei. We found that single MPFC neurons selectively encode self-reward information or partner’s reward information, whereas single dopamine neurons encode a subjective value. These findings suggest that cortico-subcortical networks play an important role in reward processing in social contexts.
