A Backup of Hippocampal Spatial Code outside the Hippocampus? New Light on Systems Memory Consolidation

In this issue of Neuron, Gridchyn et al. (2020) show that by inhibiting memory reactivations of hippocampal place maps during rest, these maps are lost but re-emerge during re-learning, suggesting that alternative extrahippocampal representations can reinstate the original hippocampal map.
