Publisher Summary This chapter focuses on sleep behavior disorder (RBD). Rapid eye movement (REM) sleep parasomnias are disorders in which undesirable physical phenomena occur predominantly during REM sleep. REM parasomnias encompass abnormal sleep-related movements, behavior, emotions, and dreaming.

Elements of three old, overlapping theories of REM sleep (REM) function, the Ontogenetic, Homeostatic and Phylogenetic hypotheses, together still provide a plausible framework - that REM (i) is directed towards early cortical development, (ii) "tones up" the sleeping cortex, (iii) can substitute for wakefulness, (iv) has a calming effect.

Rapid Eye Movement (REM) sleep Behaviour Disorder (RBD) is a REM sleep parasomnia characterized by loss of the muscle atonia that typically occurs during REM sleep, therefore allowing patients to act out their dreams. RBD manifests itself clinically as a violent behaviour occurring during the night, and is detected at the polysomnography by phasic and ...

Abstract The link between eye movements and dreaming was first suggested a long time ago, with one of the earliest accounts appearing in 1892, from a Professor G.T. Ladd, a professor of mental and moral philosophy at Yale University. He reported, through pure introspection about his own sleep, that during deep dreamless sleep his eyes ...

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.
