We present evidence disputing the hypothesis that memories are processed or consolidated in REM sleep. A review of REM deprivation (REMD) studies in animals shows these reports to be about equally divided in showing that REMD does, or does not, disrupt learning/memory. The studies supporting a relationship between REM sleep and memory have been strongly criticized for the confounding effects of very stressful REM deprivation techniques. The three major classes of antidepressant drugs, monoamine…

It is concluded that there are major methodological problems with the studies used to support the hypothesis that sleep is critically involved in memory consolidation and memory consolidation clearly occurs in both sleep and waking.
No cognitive processing in the unconscious, anesthetic‐like, state of sleep
It is argued that the brain is in an unconscious state in sleep, akin to general anesthesia (GA), and hence is incapable of meaningful cognitive processing—the sole purview of waking consciousness.
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.
Sleep-Dependent Learning and Memory Consolidation
Sleeping brain, learning brain. The role of sleep for memory systems
These studies convincingly support the idea that sleep is deeply involved in memory functions in humans and animals and confirm or reject unequivocally the recently upheld hypothesis that consolidations of non-declarative and declarative memories are respectively dependent upon REM and NREM sleep processes.
The effect of a REM sleep deprivation procedure on different aspects of memory function in humans.
This study aimed to clarify the role of REM sleep in memory by investigating aspects of memory function, processing, and modality in the same experimental setting and results show that test performance was not affected by REM sleep deprivation.

Shining a Light on the Mechanisms of Sleep for Memory Consolidation
All optogenetic studies that directly test various sleep states, traits, and circuit-level activity profiles for the consolidation of different learning tasks lend strong support to the hypothesis that sleep is essential to the consolidating of memories from the hippocampus and the consolidate of motor learning which does not necessarily involve the hippocampus.
