Animals possess the ability to infer knowledge from experience of others, the social transmission of food preference (STFP) in rodents being a prevalent laboratory model of such memory. The neurobiological mechanisms underlying SFTP, as well as the relationship between individual and social memory acquired in the same animal, remain poorly understood. The goal of the present study was to investigate these questions at the cellular level. For this purpose, we used the STFP paradigm in mice, training them to form both short-term and long-term food preference memory. Using c-Fos immunohistochemical mapping, we examined behavior-induced neuronal activation following the acquisition and retrieval of individual and social memories, thereby identifying brain regions involved in these two forms of learning. We next recorded activity of CA1 neurons during the acquisition and retrieval of both types of memories in the same freely moving mice using miniscope calcium imaging. Within this task, we discovered cognitive specialization of CA1 neurons associated with feeding, social interaction, and other behavioral acts. In the poster we present the data on activity of hippocampal CA1 neurons during acquisition and performance of the STFP task and describe the relationship between cellular representations of individually and socially acquired memories.
