The deacetylase SIRT1 has been suggested to function in normal brain physiology, but it is not known whether it participates in higher-order brain functions. These authors demonstrate a role for SIRT1 in synaptic plasticity and memory formation, with activation enhancing synaptic strength and memory formation. These effects were regulated through a post-transcriptional mechanism involving CREB activation and miR-134 production. This interplay represents another mechanism of plasticity regulation with behavioural consequences.
