Journal ArticleDOI
Ghrelin promotes slow-wave sleep in humans.
J. Weikel,Adam Wichniak,Marcus Ising,Hans Brunner,Elisabeth Friess,Katja Held,Stefan Mathias,D. A. Schmid,Manfred Uhr,Axel Steiger +9 more
TL;DR: It is suggested that ghrelin is an endogenous sleep-promoting factor that appears to be complementary to the already described effects of the peptide in the regulation of energy balance and a common stimulus of the somatotropic and hypothalamo-pituitary-adrenocortical systems.
Journal ArticleDOI
Progesterone-induced changes in sleep in male subjects
TL;DR: Some of the observed changes in sleep architecture and sleep-EEG power spectra are similar to those induced by agonistic modulators of the GABAA receptor complex and appear to be mediated in part via the conversion of progesterone into its GABA-active metabolites.
Journal ArticleDOI
Heritability of Sleep Electroencephalogram
Urte Ambrosius,Sonja Lietzenmaier,Renate Wehrle,Adam Wichniak,Stefanie Kalus,Juliane Winkelmann,Thomas Bettecken,Florian Holsboer,Alexander Yassouridis,Elisabeth Friess +9 more
TL;DR: The broad overlap of EEG frequencies during non-REM sleep and wakefulness, which shows a significant genetic variance, supports the hypothesis of common neuronal mechanisms generating EEG oscillations in humans.
Journal ArticleDOI
The hypothalamic-pituitary-adrenocortical system and sleep in man
TL;DR: This review article summarizes the major findings about the interactions of human sleep structure and the hypothalamo-pituitary-adrenocortical (HPA) system under physiological and pathophysiological conditions, including studies that probe the sleep effects of systemically administered HPA hormones.
Journal ArticleDOI
DHEA administration increases rapid eye movement sleep and EEG power in the sigma frequency range.
TL;DR: DHEA administration has a mixed GABAA-agonistic/antagonistic effect, exerted either directly or through DHEA-induced changes in steroid metabolism, which suggests the potential clinical usefulness of D HEA in age-related dementia.
