It has been hypothesized that REM (rapid eye movement) sleep has an important role in memory consolidation. The evidence for this hypothesis is reviewed and found to be weak and contradictory. Animal studies correlating changes in REM sleep parameters with learning have produced inconsistent results and are confounded by stress effects. Humans with pharmacological and brain lesion–induced suppression of REM sleep do not show memory deficits, and other human sleep-learning studies have not… 
REM sleep and memory
Differential Effects of Non-REM and REM Sleep on Memory Consolidation?
Several recent studies have related consolidation of procedural memories to SWS (or non-REM sleep)-dependent consolidation processes, and proposed future research questions to advance the understanding of the role of different sleep stages for memory consolidation.
Memory Consolidation in Sleep Dream or Reality
Causal evidence for the role of REM sleep theta rhythm in contextual memory consolidation
It is demonstrated that MSGABA neuronal activity specifically during REMS is required for normal memory consolidation, and optogenetically silenced medial septum γ-aminobutyric acid–releasing (MSGABA) neurons selectively during a REMS critical window after learning erased subsequent novel object place recognition and impaired fear-conditioned contextual memory.
Neurophysiological mechanisms of sleep-dependent memory consolidation and its facilitation by prenatal choline supplementation
Recent studies that focus on the neurophysiological changes that occur during sleep and how these sleep-dependent changes could benefit memory consolidation support the general conclusion that the types of neural plasticity supported by prenatal choline supplementation and sleep are vital for cognitive health.
The role of rapid eye movement sleep for amygdala-related memory processing
Pharmacological REM sleep suppression paradoxically improves rather than impairs skill memory
It is found that REM sleep suppression by administration of selective serotonin or norepinephrine re-uptake inhibitors after training did not impair consolidation of skills or word-pairs in healthy men but rather enhanced gains in finger tapping accuracy together with sleep spindles.
Sleep and Memory Consolidation
The reviewed work provides a clear picture of the function of sleep on memory consolidation and presents critical questions that will be essential to address regarding the extent of and limitations on sleep-dependent memory consolidation.
Posttraining increases in REM sleep intensity implicate REM sleep in memory processing and provide a biological marker of learning potential.
Increases in the intensity of REM sleep during the night of sleep following cognitive procedural/implicit task acquisition implicate REM sleep mechanisms in further off-line memory processing, and provide a biological marker of learning potential.


For half a century, "Sleep and Wakefulness" has been a valuable reference work. It discusses phases of the sleep cycle, experimental work on sleep and wakefulness, sleep disorders and their
