The ability to distinguish between familiar and novel individuals (social recognition) is key for driving social approach and is evolutionary well conserved. Social recognition is impaired in several neurodevelopmental disorders, such as autism spectrum disorder and schizophrenia. Our project aims to study the circuit and synaptic plasticity mechanisms underlying social recognition, using a combination of experimental approaches, including electrophysiology, optogenetic interventions during behaviour and mouse models of neuropsychiatric disorders.
