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.

REM sleep is the stage associated with vivid dream mentation, desynchronous cortical EEG, and atonia of antigravitary muscles. REM sleep behavior disorder (RBD) is characterized by the intermittent loss of REM sleep atonia and by the appearance of elaborate motor activity associated with dream mentation.

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 ...

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.

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.

Does the function of REM sleep concern non-REM sleep or waking?
Progress in Neurobiology, 1994We have hypothesized that REM sleep is functionally and homeostatically related to NREM sleep rather than to waking. In other words, REM sleep rather than to waking. In other words, REM sleep occurs in response to NREM-sleep expression and compensates for some process that takes place during NREM sleep.

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 ...

Development of REM sleep atonia
Acta Neurologica Scandinavica, 1999To study the functional development of neuronal systems that suppress muscle activity, we quantified the chronological change of atonia in rapid-eye-movement sleep (REMS).REMS atonia was quantified by the tonic and phasic inhibition indices (TII and PII).

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.
