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.

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 ...

Medical Clinics of North America, 2010
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.

Melatonin and Maturation of Rem Sleep
International Journal of Neuroscience, 1992The discovery in 1953 of rapid eye movement (REM) sleep and the appreciation that sleep is a heterogeneous physiological state stimulated major research into sleep disorders. Electroencephalographic studies have shown that the amount of REM sleep changes with age.
