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

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.

This is a summary of: Liu, Z. et al. The cortical amygdala consolidates a socially transmitted long-term memory. Nature 632, 366–374 (2024).
