Sleep in brain development
(Sociedad de Biología de Chile, 2007)
The time course of the probability of transition into and out of REM sleep
(American Academy of Sleep Medicine, 2009)
Study objectives: A model of rapid eye movement (REM) sleep expression is proposed that assumes underlying regulatory mechanisms operating as inhomogenous Poisson processes, the overt results of which are the transitions ...
Rapid eye movement sleep deprivation induces an increase in acetylcholinesterase activity in discrete rat brain regions
(Associação Brasileira de Divulgação Científica, 2001-01-01)
Some upper brainstem cholinergic neurons (pedunculopontine and laterodorsal tegmental nuclei) are involved in the generation of rapid eye movement (REM) sleep and project rostrally to the thalamus and caudally to the medulla ...
Sawtooth waves during REM sleep after administration of haloperidol combined with total sleep deprivation in healthy young subjects
(Associação Brasileira de Divulgação Científica, 2002-05-01)
We sought to examine the possible participation of dopaminergic receptors in the phasic events that occur during rapid eye movement (REM) sleep, known as sawtooth waves (STW). These phasic phenomena of REM sleep exhibit a ...
Differences in rem muscle activity among patients with parkinson_s disease related rem sleep behaviour disorder and patients with suspected osa. chilean experience with sinbar montages
(Elsevier, 2017)
REM sleep behavior disorder (RBD) is a parasomnia due to
an excessive muscle activity during REM sleep, expressed clinically as
acting out of dreams, potentially injurious behaviors to patient or bedmate
and high risk ...
Why modeling? Mathematical models of the human sleep/wake cycle gives new insights on the pathophysiology of fatal familial insomnia (FFI) - Porque fazer modelos? Modelos matemáticos para ciclo de vigília/sono em humanos, fornecem novos insights na fisiopatologia da insônia família fatal (IFF)
(Universidad de Belgrano - Facultad de Ingeniería y Tecnología Informática - Proyectos de Investigación, 2013)
FFI, a rare prion disease, constitutes by their wake and sleep
abnormalities a unique pathophysiological model of disease.
Recently, a neurobiological-mathematical model of the human sleep/
wake cycle (MMSWC) developed ...
Rapid eye movement sleep deprivation-induced down-regulation of beta-adrenergic receptors in the rat brainstem and hippocampus
(2004-09-01)
Rapid eye movement (REM) sleep deprivation induces a cortical down-regulation of beta-adrenergic receptors. Down-regulation of cortical beta-adrenergic receptors is consistently observed after a number of different chronic ...
Do Circadian Preferences Influence the Sleep Patterns of Night Shift Drivers?
(Karger, 2013-01-01)
Objective: The objective of this study was to analyze the effect of individual circadian preferences of drivers with fixed night work schedules on sleep patterns. Subjects and Methods: A total of 123 professional drivers, ...
Prevalência da resposta de fuga em ratas: Isto explica a diferença de gênero na agressividade da privação de sono?
(2010-12-01)
Objective: Rapid Eye Movement Sleep Deprivation (RSD) increases aggressiveness and is manifested in male rats as fighting episodes. The determination of the role played by such fights should constitute an important ...
Envelope analysis of electromyogram in rem sleep behavior disorder patients
(Elsevier, 2017)
Clinical manifestations of REM Behavior Disorder (BRD)
include REM sleep without atonia (RWA) characterized by maintenance of
muscle tonus associated to intense and frequent phasic motor events during
REM sleep episodes. ...
