The physiology of cortico-hippocampal interaction during sleep is reviewed, as well as some results on cortical replay and its relationship with hippocampal activity are reviewed.
Neuronal Oscillations and Reactivation Subserving Memory Consolidation
- Biology, Psychology
- 2017
This chapter provides a conceptual introduction to system memory consolidation, describes the neuronal mechanisms thought to underlie the generation of and interaction between SOs, spindles and ripples, and discusses how these oscillations presumably mediate memory reactivation and hippocampo-neocortical cross-talk.
The organization of recent and remote memories
- Biology, PsychologyNature Reviews Neuroscience
- 2005
Recent studies have begun to shed light on how remote memories are organized in the cortex, and the molecular and cellular events that underlie their consolidation.
Dynamic Hippocampal Circuits Support Learning- and Memory-Guided Behaviors.
- Biology, PsychologyCold Spring Harbor symposia on quantitative biology

Key findings from the laboratory are summarized, with a focus on recent discoveries that indicate that the rat hippocampus supports learning and decision-making behaviors via dynamic and smooth transitions in neural representation, internal processing state, and coupling with related brain structures.
Memory Replay in the Hippocampus
- Biology, Psychology

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.

Hippocampal replay in the awake state: a potential substrate for memory consolidation and retrieval
- Psychology, BiologyNature Neuroscience
- 2011
The repetition of learned sequences on a compressed time scale is well suited to promote memory consolidation in distributed circuits beyond the hippocampus, suggesting that consolidation occurs in both the awake and sleeping animal.
Offline reactivation of experience-dependent neuronal firing patterns in the rat ventral tegmental area.
- Biology, PsychologyJournal of neurophysiology

It is provided new evidence that rodent ventral tegmental area (VTA) neurons are selective for different types of food stimuli and that stimulus-sensitive neurons strongly reactivate during the rest period following a task that involved those stimuli.

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.

It is indicated that hippocampal neural activity is necessary for both encoding and retrieval of spatial memory and for either trace consolidation or long-term storage.

Hippocampal cells that fire together during behaviour exhibit enhanced activity correlations during subsequent sleep, with some preservation of temporal order information, and traces of recent experience are re-expressed in both hippocampal and neocortical circuits during sleep.

Replay of Neuronal Firing Sequences in Rat Hippocampus During Sleep Following Spatial Experience
- Biology, PsychologyScience
- 1996
The correlated activity of rat hippocampal pyramidal cells during sleep reflects the activity of those cells during earlier spatial exploration and this memory for temporal order of neuronal firing could be produced by an interaction between the temporal integration properties of long-term potentiation and the phase shifting of spike activity with respect to the hippocampal theta rhythm.

Whether ensemble firing patterns of granule cells in the fascia dentata (FD), an area ‘upstream’ from CA3, are also reactivated during sleep is investigated to extend the understanding of the generality of this phenomenon.
Encoding and retrieval of episodic memories: Role of cholinergic and GABAergic modulation in the hippocampus

This research focuses on linking episodic memory function to the cellular physiology of hippocampal neurons, with a particular emphasis on modulatory effects at cholinergic and γ‐aminobutyric acid B receptors, and a network simulation which can replicate the selective encoding impairment produced by scopolamine in human subjects.

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.
