Despite a growing understanding of the molecular and developmental basis of autism spectrum disorder (ASD), how the neuronal encoding of social information is precisely disrupted in ASD and whether it contributes to abnormal social behavior remains unclear. Here, we disrupted and then restored expression of the ASD-associated gene Shank3 in adult male mice while tracking the encoding dynamics of neurons in the medial prefrontal cortex (mPFC) over weeks. We find that Shank3 disruption led to reduction of neurons encoding the experience of other mice and increase in neurons encoding the animal’s own. This shift was associated with loss of ability by neurons to distinguish other-from-self and, therefore, the inability to encode social agency. Restoration of Shank3 expression in the mPFC reversed this encoding imbalance and increased sociability over 5-8 weeks. These findings reveal a neuronal encoding process that is necessary for social behavior and that may be disrupted in ASD.
