Publisher Summary This chapter focuses on the cellular and neurophysiological/neuropharmacological, with most of the emphasis on mechanisms relevant to rapid eye movement (REM) sleep. The chapter presents the sleep architecture and phylogeny/ontogeny so as to provide a basis for the later mechanistic discussions.

Breakdown in REM sleep circuitry underlies REM sleep behavior disorder
Trends in Neurosciences, 2014During rapid eye movement (REM) sleep, skeletal muscles are almost paralyzed. However, in REM sleep behavior disorder (RBD), which is a rare neurological condition, muscle atonia is lost, leaving afflicted individuals free to enact their dreams. Although this may sound innocuous, it is not, given that patients with RBD often injure themselves or their ...

To test whether mental activities collected from non-REM sleep are influenced by REM sleep, we suppressed REM sleep using clomipramine 50mg (an antidepressant) or placebo in the evening, in a double blind cross-over design, in 11 healthy young men. Subjects were awakened every hour and asked about their mental activity.

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.

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.

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 ...

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 ...

Neurobiology of REM and NREM sleep
Sleep Medicine, 2007This paper presents an overview of the current knowledge of the neurophysiology and cellular pharmacology of sleep mechanisms. It is written from the perspective that recent years have seen a remarkable development of knowledge about sleep mechanisms, due to the capability of current cellular neurophysiological, pharmacological and molecular techniques
