TLDR
Sleep has been identified as a state that optimizes the consolidation of newly acquired information in memory, depending on the specific conditions of learning and the timing of sleep, through specific patterns of neuromodulatory activity and electric field potential oscillations.Abstract:
Sleep improves the consolidation of both declarative and non-declarative memories. Diekelmann and Born discuss the potential mechanisms through which slow wave sleep and rapid eye movement sleep support system and synaptic consolidation. Sleep has been identified as a state that optimizes the consolidation of newly acquired information in memory, depending on the specific conditions of learning and the timing of sleep. Consolidation during sleep promotes both quantitative and qualitative changes of memory representations. Through specific patterns of neuromodulatory activity and electric field potential oscillations, slow-wave sleep (SWS) and rapid eye movement (REM) sleep support system consolidation and synaptic consolidation, respectively. During SWS, slow oscillations, spindles and ripples — at minimum cholinergic activity — coordinate the re-activation and redistribution of hippocampus-dependent memories to neocortical sites, whereas during REM sleep, local increases in plasticity-related immediate-early gene activity — at high cholinergic and theta activity — might favour the subsequent synaptic consolidation of memories in the cortex.read more

Beta-band oscillations--signalling the status quo?
Andreas K. Engel,Pascal Fries +1 more
TL;DR: In this article, the potential functional role of the beta-band oscillations in cognitive processing, on the motor system and on the pathophysiology of movement disorders is discussed. But the authors focus on the maintenance of the current sensorimotor or cognitive state.

Beta-band oscillations--signalling the status quo?
Andreas K. Engel,Pascal Fries +1 more
TL;DR: It is hypothesized that beta oscillations and/or coupling in the beta-band are expressed more strongly if the maintenance of the status quo is intended or predicted, than if a change is expected.

Giulio Tononi,Chiara Cirelli +1 more
TL;DR: This Perspective considers the rationale and evidence for the synaptic homeostasis hypothesis (SHY), and points to open issues related to sleep and plasticity.

Neuronal Oscillations in Cortical Networks
György Buzsáki,Andreas Draguhn +1 more
TL;DR: Recent findings indicate that network oscillations bias input selection, temporally link neurons into assemblies, and facilitate synaptic plasticity, mechanisms that cooperatively support temporal representation and long-term consolidation of information.

The Organization of Behavior: A Neuropsychological Theory
TL;DR: In this paper, the authors discuss the first stage of perception: growth of the assembly, the phase sequence, and the problem of Motivational Drift, which is the line of attack.

Why there are complementary learning systems in the hippocampus and neocortex: insights from the successes and failures of connectionist models of learning and memory.
TL;DR: The account presented here suggests that memories are first stored via synaptic changes in the hippocampal system, that these changes support reinstatement of recent memories in the neocortex, that neocortical synapses change a little on each reinstatement, and that remote memory is based on accumulated neocorticals changes.
