Social recognition is the ability of an individual to identify and remember conspecifics based on previous encounters. It represents a form of social memory that is crucial for social species, as it influences decision-making, pair bonding, and the establishment of dominance hierarchies. Mice and rats are commonly used to investigate the mechanisms underlying memory formation, including Social Recognition Memory (SRM), due to their strong social behavior and natural preference for novel conspecifics over familiar ones. This behavioral trait facilitates the assessment of SRM in experimental settings. The Social Recognition Task (SRT) is a widely used paradigm to evaluate SRM. In our protocol, the experimental subject explores two unfamiliar conspecifics during a training session. One hour later, a test session is performed in which the subject is presented with one familiar and one novel conspecific. A preferential interaction with the novel conspecific is interpreted as evidence of SRM formation. One of the main goals of our work is to understand the role of oxytocin (OXT) in the formation of SRM. In this project, we focus on investigating plastic changes in brain regions that express OXT receptors, such as the hippocampus, using techniques like ex vivo extracellular recordings and patch-clamp, in mice that underwent the SRT. Elucidating the biological basis of SRM formation may contribute to a better understanding of disorders involving social cognition deficits.
