For many mammals, the ability to recognize familiar conspecifics (social memory) relies primarily on olfaction. It is based on the specific combination of body chemosignals which forms the unique olfactory “footprint” of each individual. Social recognition is dependent on an intact main olfactory system since it is impaired in anosmic mice and social odors are sufficient to form a memory of specific individuals. Our team investigates the neuronal mechanisms underpinning social recognition memory with a focus on the dialog between olfactory and memory networks.
