A continuum model for the dynamics of the phase transition from slow-wave sleep to REM sleep [PDF]
, 2010 Previous studies have shown that activated cortical states (awake and rapid eye-movement (REM) sleep), are associated with increased cholinergic input into the cerebral cortex.

The sleep-wakefulness cycle of Wistar rats with spontaneous absence-like epilepsy
Acta Scientiarum: Biological Sciences, 2015 Possible interactions between the sleep-wakefulness cycle and a new kind of spontaneous epilepsy, expressed as absence-like seizures and spike-wave bursts in FMUSP rats, are evaluated.

The involvement of noradrenaline in rapid eye movement (REM) sleep mentation
Frontiers in Neurology, 2011 Noradrenaline, one of the main brain monoamines, has powerful central influences on neurobiological processes in the forebrain which support the mental activities occurring during the sleep–waking cycle. Noradrenergic neurons are activated during waking,

Rapid eye movements during paradoxical sleep in patients with cerebrovascular disease [PDF]
Arquivos de Neuro-Psiquiatria, 2000 Rapid eye movements that occur during paradoxical sleep are generated from the brainstem and are modulated by cerebral hemispheres. In an attempt to establish the participation of cerebral hemispheres on rapid eye movements, we carried out a quantitative

Frontiers in Neurology, 2012 Sleep is characterized as rapid eye movement (REM) and non-rapid eye movement (NREM) sleep. Studies suggest that wake-related neurons in the basal forebrain, posterior hypothalamus and brainstem and NREM sleep-related neurons in the anterior-hypothalamic

Sleep Deprivation in the Rat: IV. Paradoxical Sleep Deprivation [PDF]
Sleep, 1989 Twelve rats were subjected to paradoxical sleep deprivation (PSD) by the disk apparatus. All PSD rats died or were sacrificed when death seemed imminent within 16-54 days. No anatomical cause of death was identified. All PSD rats showed a debilitated appearance, lesions on their tails and paws, and weight loss in spite of increased food intake.

Paradoxical sleep deprivation changes testicular malondialdehyde and caspase-3 expression in male rats [PDF]
Universa Medicina, 2015 BACKGROUND Sleep deprivation is a significant problem among adult men and is considered as a risk factor for several diseases. Paradoxical sleep deprivation (PSD) induces Leydig cell apoptosis through elevation of corticosterone, with testicular ...

Nonlinear aspects of the EEG during sleep in children [PDF]
, 2005 Electroencephalograph (EEG) analysis enables the neuronal behavior of a section of the brain to be examined. If the behavior is nonlinear then nonlinear tools can be used to glean information on brain behavior, and aid in the diagnosis of sleep ...
