A brain circuit that cements the memory of socially learnt food preferences

Nature, Published online: 18 September 2024; doi:10.1038/d41586-024-03012-1

How an experience results in a long-term memory has remained unknown. A circuit involving the posteromedial nucleus of the cortical amygdala in the brain is shown to consolidate memories for socially transmitted food preferences in mice using a gene-transcriptional mechanism without contributing to memory acquisition, storage or retrieval.
