Sleep, Slow-Wave Sleep, and Blood Pressure

Current Hypertension Reports, 2012
There is increasing evidence that alterations in sleep continuity due to central nervous system arousal and/or reductions in deeper stages of sleep adversely affect blood pressure and contribute to hypertension. Disturbed sleep also blunts the normal nocturnal dip in blood pressure and may lead to sustained daytime hypertension as well. Nocturnal drops

Experience-dependent slow-wave sleep development

Nature Neuroscience, 2003
Sleep enhances plasticity in neocortex, and thereby improves sensory learning. Here we show that sleep itself undergoes changes as a consequence of waking experience during a late critical period in cats and mice. Dark-rearing produced a robust and reversible decrement of slow-wave electrical activity during sleep that was restricted to visual cortex ...

Human Slow Wave Sleep

European Neurology, 1986
Human slow wave sleep (hSWS) is an important form of sleep that seems to take priority over REM sleep. Although hSWS is commonly thought to be associated with enhanced tissue repair, evidence supporting this view is questioned. For example, total sleep deprivation and loss of hSWS have little or no adverse effect on body functioning outside the brain ...

Slow-wave sleep and androgens: selective slow-wave sleep suppression affects testosterone and 17α-hydroxyprogesterone secretion

Sleep Medicine, 2018
Levels of steroid hormones such as androgens and cortisol exhibit circadian variation, and their fluctuations are related to the sleep-wake cycle. Currently, the functional role of different stages of sleep in steroid hormone secretion remains unclear.

Global control of sleep slow wave activity

Nature Neuroscience, 2020
One hallmark of sleep is the slow oscillation, which is often synchronous across the neocortical mantle. How this synchrony is achieved remains unclear. A new study by Narikiyo et al. demonstrates how the claustrum may play a key role in the global control of this rhythm.

Ghrelin promotes slow-wave sleep in humans

American Journal of Physiology-Endocrinology and Metabolism, 2003
Ghrelin, an endogenous ligand of the growth hormone (GH) secretagogue (GHS) receptor, stimulates GH release, appetite, and weight gain in humans and rodents. Synthetic GHSs modulate sleep electroencephalogram (EEG) and nocturnal hormone secretion. We studied the effect of 4 × 50 μg of ghrelin administered hourly as intravenous boluses between 2200 and
