Increased cortical excitability after selective REM sleep deprivation in healthy humans: a transcranial magnetic stimulation study [PDF]

open access: yes, 2013
REM sleep has antiepileptogenic properties whereas, its loss is known to have a proconvulsive role. However, the mechanisms underlying the proepileptogenic effects of REM sleep deprivation are yet not fully understood.

REM Sleep Characteristics in Narcolepsy and REM Sleep Behavior Disorder [PDF]

open access: yesSleep, 2007
To assess the presence of polysomnographic characteristics of REM sleep behavior disorder (RBD) in narcolepsy; and to quantify REM sleep parameters in patients with narcolepsy, in patients with "idiopathic" RBD, and in normal controls.Sleep laboratory studySixteen patients with narcolepsy and cataplexy matched for age and sex with 16 patients with ...

Neuronal avalanches differ from wakefulness to deep sleep - evidence from intracranial depth recordings in humans [PDF]

open access: yes, 2013
Neuronal activity differs between wakefulness and sleep states. In contrast, an attractor state, called self-organized critical (SOC), was proposed to govern brain dynamics because it allows for optimal information coding.

Characterization of Sleep Stages by Correlations of Heartbeat Increments

open access: yes, 2002
We study correlation properties of the magnitude and the sign of the increments in the time intervals between successive heartbeats during light sleep, deep sleep, and REM sleep using the detrended fluctuation analysis method.

Effects of valerian extract on the sleep-wake cycle in sleep-disturbed rats. [PDF]

open access: yes, 2005
The present study was performed to investigate the effects of valerian extract on the sleep-wake cycle using sleep-disturbed model rats. A significant shortening in sleep latency was observed with valerian extract at doses of 1000 and 3000 mg/kg.

Nefazodone and REM Sleep: How Do Antidepressant Drugs Decrease REM Sleep? [PDF]

open access: yesSleep, 1998
In previous uncontrolled studies, nefazodone, a new antidepressant drug, increased REM sleep or had no effect on REM sleep. We report a double-blind, placebo-controlled, parallel group study on effects of nefazodone (N) on polysomnographic sleep variables in healthy human volunteers.
