We propose that the function of dream sleep (more properly rapid-eye movement or REM sleep) is to remove certain undesirable modes of interaction in networks of cells in the cerebral cortex. We postulate that this is done in REM sleep by a reverse learning mechanism (see also p. 158), so that the trace in the brain of the unconscious dream is weakened, rather than strengthened, by the dream. 
The biology and function of rapid eye movement sleep
  • J. Winson
  • Biology, Medicine
  • Current Opinion in Neurobiology
  • 1993
TLDR
Rapid eye movement sleep, a stage of sleep that appears to be present in all marsupial and terrestrial placental mammals, was first identified in 1953 and suggests a role in memory processing. Expand
The cognitive neuroscience of sleep: neuronal systems, consciousness and learning
TLDR
This work discusses neuronal-network and regional forebrain activity during sleep, and its consequences for consciousness and cognition, and indicates possible roles for sleep in neuroplasticity. Expand
A state of confusion in information processing makes the sleeping brain a dream generator
Dreams, generated by the sleeping brain, are one of the most common and fascinating phenomena of human mind. But the role and mechanism of dreaming remain largely unknown. This paper provided theExpand
Alertness, Quiet Sleep, Dreaming
TLDR
The fluctuation in the electrical activity of the cerebrum during various behavioral conditions, as reflected in EEG waves, evoked potentials, and activities of different types of thalamic and cortical neurons is discussed. Expand
Is Dreaming Related to Sleep-Dependent Memory Consolidation?
As testing the functions of dreams directly is not possible, empirical dream research has focused on three areas providing indirect support for a relationship between dreaming and sleep-dependentExpand
Genes, Sleep and Dreams
This Chapter considers the continuing debate regarding the mechanisms that underlie the cognitive role of sleep. One theory proposes that the triggering of generalized synaptic downscaling occurs soExpand
The function of dreams (REM sleep): roles for the hippocampus, melatonin, monoamines, and vasotocin.
TLDR
REM sleep, melatonin, and monoamines may be involved in the transfer of memory from the intermediate-term high-capacity buffer in the hippocampus into long-term memory storage in the neocortex. Expand
Crick and Mitchison's theory of REM sleep and neural networks.
  • D. Brown
  • Psychology, Medicine
  • Medical hypotheses
  • 1993
TLDR
The theory of reverse learning might lead to an understanding of why lithium salts terminate manic episodes and might account for some aspects of schizophrenia, mania, and depression. Expand
A life-sustaining function for REM sleep: A theory
  • R. Vertes
  • Medicine, Psychology
  • Neuroscience & Biobehavioral Reviews
  • 1987
TLDR
The possibility that two fatal sleep-associated syndromes (Sudden Infant Death Syndrome and the Oriental Nocturnal Death Syndrome) may involve deficits of REM was discussed and the mechanism used by the brain to promote and ensure recovery from sleep was discussed. Expand
Circuit mechanisms and computational models of REM sleep
TLDR
An up-to-date picture of REM-sleep-regulating circuits is reviewed and a brief overview of computational models for REM sleep regulation is provided. Expand

The unexpected finding that such abundant dreaming occurs at regular intervals every night strengthened the hypothesis that dreaming might be essential. Expand

TLDR
The authors suggest that the automatically activated forebrain synthesizes the dream by comparing information generated in specific brain stem circuits with information stored in memory. Expand

TLDR
Thresholds for electroconvulsive shock dropped significantly after deprivation in rats, but thresholds in control animals treated in a similar manner, but allowed REM sleep exhibited no change, suggesting deprivation seems to heighten neural excitability. Expand

TLDR
It is suggested that moderate REM deprivation was accompanied by more positive changes in waking behaviors for Ss whose fantasy tended to be REM-state specific than for those whose fantasy mentation was generally more available throughout sleep and waking states. Expand
