Effects of alcohol on sleep parameters of sleep-deprived healthy volunteers
, 1997 Both partial and total sleep deprivation frequently result in a rebound of paradoxical sleep (PS), as well as of slow-wave or delta sleep. Acute administration of ethanol inhibits PS in normal volunteers.

Sleepless Yet Asleep: A Case Report on Paradoxical Insomnia
National Board of Examinations Journal of Medical SciencesBackground: Paradoxical insomnia, also termed sleep state misperception, is a subtype of chronic insomnia in which a patient's subjective report of severely disturbed or absent sleep is markedly discordant with objective evidence of normal sleep duration

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

Melanin-concentrating hormone (MCH): role in REM sleep and depression
Frontiers in Neuroscience, 2015 The melanin-concentrating hormone (MCH) is a peptidergic neuromodulator synthesized by neurons of the lateral hypothalamus and incerto-hypothalamic area. MCHergic neurons project throughout the central nervous system, including areas such as the dorsal (

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.

Effects of paradoxical sleep deprivation on thermoregulation in the rat
, 1998 Rats were subjected to chronic paradoxical sleep deprivation (PSD) by the disk-over-water method to determine if they would develop the sustained increase in core (hypothalamic) temperature (T(hy)); elevated temperature set-point (T(set)); and the ...

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level
Aging and Cancer, EarlyView.This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Circadian and ultradian NREM-REM sleep modulation of dream recall : effects of age and spectral activity [PDF]
, 2011 This thesis deals with the electrophysiological correlates of sleep prior to dream recall and the age-related effects on dream processing. The dual NREM/REM sleep cycle and the circadian modulation of REM sleep sum to generate dream processing.
