Abstract Study Objective: Slow-wave activity (SWA; 0.5–4.0 Hz) during non-rapid eye
movement (NREM) sleep is a reliable indicator of sleep need, as it increases with the …

Slow-wave activity (SWA), the EEG power between 0.5 and 4 Hz during non-rapid eye
movement (NREM) sleep, is one of the best characterized markers of sleep need, because it …

Abstract Study Objective: The best characterized marker of sleep homeostasis is the amount
of slow wave activity (SWA, 0.5–4 Hz) during NREM sleep. SWA increases as a function of …

The brain-derived neurotrophic factor (BDNF) mediates the plasticity-related changes that
associate with memory processing during sleep. Sleep deprivation and chronic stress are …

Rats were subjected to nonselective sleep disturbance for short periods under conditions
designed to minimize the adverse influence of external stresses, such as environmental …

Homeostatic regulation of REM sleep plays a key role in neural plasticity and deficits in this
process are implicated in the development of many neuropsychiatric disorders. Little is …

In most mammalian species studied, two distinct and successive phases of sleep, slow wave
(SW), and rapid eye movement (REM), can be recognized on the basis of their EEG profiles …

Endogenous expression levels of brain-derived neurotrophic factor (BDNF) mRNA were
assessed using in situ hybridization to investigate whether there is a natural diurnal …

Study Objectives: EEG slow waves are the hallmark of deep NREM sleep and may reflect
the restorative functions of sleep. Evidence suggests that increased sleep slow waves after …

Sleep is ubiquitous in animals and humans, but its function remains to be further
determined. The synaptic homeostasis hypothesis of sleep–wake regulation proposes a …
