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… 
Hippocampus Whispering in Deep Sleep to Prefrontal Cortex—For Good Memories?
Hippocampal memory consolidation during sleep: a comparison of mammals and birds
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.
Replay of rule-learning related neural patterns in the prefrontal cortex during sleep
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.
Cortico-Hippocampal Circuits for Memory Consolidation: The Role of the Prefrontal Cortex
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.
Deciphering Neural Codes of Memory during Sleep
Localizing spontaneous memory reprocessing during human sleep
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.
Memory stabilization with targeted reactivation during human slow-wave sleep
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.


Coordinated memory replay in the visual cortex and hippocampus during sleep
It is found that spiking patterns not only in the cortex but also in the hippocampus were organized into frames, defined as periods of stepwise increase in neuronal population activity.
Reactivation of hippocampal ensemble memories during sleep.
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.
Experience-dependent changes in cerebral activation during human REM sleep
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 Ventral Striatum in Off-Line Processing: Ensemble Reactivation during Sleep and Modulation by Hippocampal Ripples
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.
Reactivation of Hippocampal Cell Assemblies: Effects of Behavioral State, Experience, and EEG Dynamics
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.
Memory consolidation during sleep: a neurophysiological perspective.
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.
Declarative memory consolidation in humans: a prospective functional magnetic resonance imaging study.
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.
