| Outline of Final Research Achievements |
Many social animals, including humans, can recognize and remember other individuals (i.e. having "social memory") and elicit appropriate social behaviors toward each individual. Although we previously found that social memory is stored in the ventral CA1 neurons in the hippocampus (Science, 2016), how the social memory is associate with emotional valences to generate feelings of "like/dislike" toward specific persons. In this study, our results showed that ventral CA1 neurons storing social memories have a direct neural projection to the amygdala, and these neural circuits were essential to associate social memory with positive and negative valence information.
