As critical as waking brain function is to cognition, an extensive literature now indicates that sleep supports equally important, different yet complementary operations. This review will consider recent and emerging findings implicating sleep and specific sleep‐stage physiologies in the modulation, regulation, and even preparation of cognitive and emotional brain processes. First, evidence for the role of sleep in memory processing will be discussed, principally focusing on declarative memory… 
Sleep and emotional processing.
Overnight therapy? The role of sleep in emotional brain processing.
A rapid eye movement (REM) sleep hypothesis of emotional-memory processing is proposed, the implications of which may provide brain-based insights into the association between sleep abnormalities and the initiation and maintenance of mood disturbances.
Sleep and Emotional Memory Processing.
Sleep And Memory Processing: A Solid Relationship
It’s of note that SWS improves sleep-dependent motor adaptation, while spindles facilitates sleep- dependent, motor sequence task, and Emotional memory enhancement is strongly associated with REM sleep activity, involving the right-dominant prefrontal theta activity.
About sleep's role in memory.
This review aims to comprehensively cover the field of "sleep and memory" research by providing a historical perspective on concepts and a discussion of more recent key findings.
The role of sleep in human declarative memory consolidation.
Focusing on the declarative memory system in humans, the literature regarding the benefits of sleep for both neutral and emotionally salient declaratives memory is reviewed and the impact of sleep on emotion regulation is discussed.
Relief Expectation and Sleep
It is demonstrated that the mediating effect of expectation on placebo-induced analgesia is strengthened by sleep, and that the individual amount of REM sleep is predictive of the relief expected on the next morning.

Aside from memory storage capabilities, memory consolidation also appears to reorganize and integrate memories with preexisting knowledge, which may facilitate the discovery of underlying rules and associations that benefit other cognitive functioning, including problem solving and creativity.
Nocturnal Mnemonics: Sleep and Hippocampal Memory Processing
This overview examines the specific contribution of sleep to human hippocampal memory processing; both the detriments caused by a lack of sleep, and conversely, the proactive benefits that develop following the presence of sleep.
The role of sleep and dreaming in the processing of episodic memory
If spatial memory, previously shown to be strongly associated with SWS, shifts to a REM sleep association if emotional elements are associated with the task, it is shown that the presence of emotions during a task may modulate the sleep stage with which its consolidation is associated.


A refined model of sleep and the time course of memory formation.

A new neurocognitive framework of procedural learning is offered, consisting first of acquisition, followed by two specific stages of consolidation, one involving a process of stabilization, the other involving enhancement, whereby delayed learning occurs.
The sequential hypothesis of the function of sleep
REM Sleep, Prefrontal Theta, and the Consolidation of Human Emotional Memory
Data support the role of REM-sleep neurobiology in the consolidation of emotional human memories, findings that have direct translational implications for affective psychiatric and mood disorders.
The human emotional brain without sleep — a prefrontal amygdala disconnect
Sleep Facilitates Consolidation of Emotional Declarative Memory
It is suggested that the facilitation of memory for emotionally salient information may preferentially develop during sleep, and recognition bias for remember judgments of these stimuli increased by 58% after sleep relative to wake (resulting in more conservative responding).
A deficit in the ability to form new human memories without sleep
It appears that sleep before learning is critical in preparing the human brain for next-day memory formation—a worrying finding considering society's increasing erosion of sleep time.
Different roles for REM and stage 2 sleep in motor learning: A proposed model
A model is developed to explain how motor skills tasks involving REM and Stage 2 sleep might be dependent on two separate, but overlapping, neural systems.
Sleep, memory, and plasticity.
Findings from a large body of work on the role of sleep in memory encoding, memory consolidation, brain plasticity, and memory reconsolidation are reviewed, focusing specifically on sleep-dependent memory processing.
Interfering with Theories of Sleep and Memory: Sleep, Declarative Memory, and Associative Interference
Sleep-Related Hippocampo-Cortical Interplay during Emotional Memory Recollection
The results suggest that the emotional significance of memories influences their sleep-dependent systems-level consolidation, and the recruitment of hippocampo-neocortical networks during recollection is enhanced after sleep and is hindered by sleep deprivation.
