As previously shown in the hippocampus and other brain areas, patterns of firing-rate correlations between neurons in the rat medial prefrontal cortex during a repetitive sequence task were preserved during subsequent sleep, suggesting that waking patterns are reactivated. We found that, during sleep, reactivation of spatiotemporal patterns was coherent across the network and compressed in time by a factor of 6 to 7. Thus, when behavioral constraints are removed, the brain's intrinsic…

Avian sleep does not appear to be involved in transferring hippocampal memories to other brain regions, and the slow‐oscillation, the defining feature of mammalian and avian SWS, may serve a more general function independent of that related to coordinating the transfer of information from the hippocampus to the PFC in mammals.

Recording neuron ensembles in the rat medial prefrontal cortex to study memory trace reactivation during SWS following learning and execution of cross-modal strategy shifts found that learning influenced which patterns were most strongly encoded and successively reactivated in the hippocampal/prefrontal network.

Some of the experimental evidence on memory replay and dynamical interactions between cortex and hippocampus during sleep are reviewed, with a focus on the prefrontal cortex, one of the key cortical areas for memory.
Decoding material-specific memory reprocessing during sleep in humans

It is shown that memory reprocessing occurs in both NREM and REM sleep in humans and that it pertains to different aspects of the consolidation process, as well as two distinct underlying mechanisms between these states.

Overall, noninvasively demonstrate localized, coordinated memory reprocessing in human sleep by applying machine learning to source space-transformed magnetoencephalographic data in a two-step exploratory and confirmatory study design.
Memory Replay in the Hippocampus

Since memory replay during SWRs has the capacity to recreate patterns of activity associated with past experience in hippocampal–neocortical circuits, it is well suited to support memory retrieval.

The results suggest that the brain is differentially activated by studied and unstudied sounds during deep sleep and that the thalamus and medial temporal lobe are involved in establishing the mnemonic consequences of externally triggered reactivation of associative memories.

Recordings from large ensembles of hippocampal "place cells" in three rats showed that cells that fired together when the animal occupied particular locations in the environment exhibited an increased tendency to fire together during subsequent sleep, in comparison to sleep episodes preceding the behavioral tasks.

Using positron emission tomography and regional cerebral blood flow measurements, it is shown that waking experience influences regional brain activity during subsequent sleep and supports the hypothesis that memory traces are processed during REM sleep in humans.

The data suggest, first, the occurrence of pattern replay in a subcortical structure implied in the processing and prediction of reward and, second, a functional linkage between ventral striatal reactivation and a specific type of high-frequency population activity associated with hippocampal replay.

Pattern reinstatement was strongest during sharp wave–ripple oscillations, suggesting that these events may reflect system convergence onto attractor states corresponding to previous experiences, and do not necessarily reflect persistence of an active memory.

It is suggested that sleep patterns in the limbic system are essential for the preservation of experience-induced synaptic modifications, and the subcortical effects of hippocampal sharp wave bursts may be critical in the release of various hormones which, in turn, may affect synaptic plasticity.

Over the course of the entire study, hippocampal activity for correct confident recognition continued to decrease, whereas activity in a ventral medial prefrontal region increased, which may prompt a revision of classical consolidation theory, incorporating a transfer of putative linking nodes from hippocampal to prelimbic prefrontal areas.
