The astrocytic ensemble acts as a multiday trace to stabilize memory - Nature

Recall transiently destabilizes memories, which require re-stabilization to become long-lasting. Despite its importance in human cognition and neuropsychiatric disorders6,7, the mechanisms that specifically stabilize memories of critical experiences-those that are essential for survival and frequently marked by emotional salience and repetition-remain incompletely understood. Memory traces are linked to specialized neuronal ensembles (neuronal engrams), which include neuronal populations that become Fos+ during both initial and repeated experiences8.
