The paper shows that generative replay occurs in primary visual cortex during sleep, influenced by hippocampal activity, suggesting a mechanism for building hierarchical generative models for flexible behavior.

The paper shows that forming a robust memory restricts hippocampal coactivity, impairing flexible memory formation, and that optogenetic suppression during robust memory formation restores flexibility.

The paper investigates how neural coactivity encodes dynamic memory in mice, finding that contingency discrimination relies on emergent coactivity patterns rather than individual neuron tuning.
