Partial cellular reprogramming can modulate aging-associated decline across multiple tissues. However, whether targeting memory-encoding ensembles within specific brain regions is sufficient to restore cognitive function has remained unknown. In this issue of Neuron, Berdugo-Vega et al. show that engram rejuvenation rescues memory deficits and restores epigenetic-transcriptional features and intrinsic excitability.
