Abstract

We examined juvenile social recognition and discrimination in mice with early post-natal onset, transgenic CRF over-expression (CRF-OE) and in their wild-type littermates (WT). CRF-OE mice showed enhanced social investigation during the first encounter, normal short-term and facilitated long-term social recognition memory, compared to WT. These results suggest that chronically elevated brain CRF tone may contribute in better remembering ethologically relevant and emotionally salient stimuli, such as social interaction.
