The paper identifies how vCA1 neurons in mice encode social identities and properties like sex and strain using rate and theta-based coding, with sex-specific memory reactivation and disruption effects observed.

This study shows that specific Shank3 knockout in ventral CA1 neurons impairs social memory in mice, revealing a threshold for neuronal disruption required for this impairment.

The paper investigates how long-term social memory about female conspecifics in male mice is mediated by the ventral hippocampus and nucleus accumbens, showing differential modulation of dopamine receptor neurons.

This study shows that disrupted social memory ensembles in the ventral hippocampus of Shank3 mutant mice correlate with impaired social behavior, suggesting a role in autism-associated social amnesia.
