REM sleep and neurodegeneration
Journal of Sleep ResearchSummarySeveral brainstem, subcortical and cortical areas are involved in the generation of rapid eye movement (REM) sleep. The alteration of these structures as a result of a neurodegenerative process may therefore lead to REM sleep anomalies.

Rapid eye movement sleep behavior disorder (RBD) is a brain disorder, characterized by the dream enactment during rapid eye movement (REM) sleep due to a lack of physiologic muscle atonia and increased muscle twitching. Schenk was the first to describe this disorder in 1986; however, few authors reported in the 1970-1980s loss of physiological muscle ...

Journal of Sleep Research, 1993 SUMMARY The discovery, 40 years ago, of REM sleep and of its putative association with dreaming in the adult human raised the possibility that neuroscientific investigations of REM‐sleep physiology would someday ‘explain’ the distinctive features of dream experience. I argue here against the possibility, since replicated psychological data demonstrate

We review the literature on the neurobiology of rapid eye movement (REM) and non-rapid eye movement (NREM) sleep states and associated dreams. REM is associated with enhanced activation of limbic and amygdalar networks and decreased activation in dorsal prefrontal regions while stage II NREM is associated with greater cortical activation than REM.

The neuropsychology of REM sleep dreaming
NeuroReport, 1998Recent PET imaging and brain lesion studies in humans are integrated with new basic research findings at the cellular level in animals to explain how the formal cognitive features of dreaming may be the combined product of a shift in neuromodulatory balance of the brain and a related redistribution of regional blood flow.

The broad features of rapid eye movement (REM) sleep are reviewed. Memory storage in the brain is probably quite unlike that in a digital computer, being distributed, superimposed and robust. Such memory systems are easily overloaded. If the stored memories share common features, random stimulation often produces mixed outputs.

A Review of REM Sleep Deprivation
Archives of General Psychiatry, 1975Studies on the behavioral consequences of rapid eye movement (REM) sleep deprivation in animals and humans are critically reviewed. In animals, converging evidence--some reasonably well controlled--indicates that REM sleep deprivation probably heightens central neural excitability and increased motivational behavior, but has nuclear or inconclusive ...

The divorce of REM sleep and dreaming
Behavioral and Brain Sciences, 2000The validity of dream recall is discussed. What is the relation between the actual dream and its later reflection? Nielsen proposes differential sleep mentation, which is probably determined by dream accessibility. Solms argues that REM sleep and dreaming are double dissociable states.

REM sleep behavior disorder (RBD), formally recognized in the 1980s, is an infrequent but spectacular parasomnia characterized by dream enactment, leading to aggressive or complex behaviors. It essentially affects older men, and many years may go by before medical attention is sought.

Rapid eye movement (REM) sleep behavior disorder (RBD) was formally identified and named in 1986–1987 and is characterized by loss of REM sleep atonia with the release of complex, aggressive, and violent behaviors that are often simultaneous enactments of abnormal dreams involving confrontation by unfamiliar people and animals, with the dreamer rarely ...
