Journal ArticleDOI
PER3 Polymorphism Predicts Sleep Structure and Waking Performance
Antoine U. Viola,Simon Archer,LM James,John A. Groeger,June C. Lo,Debra J. Skene,Malcolm von Schantz,Derk-Jan Dijk +7 more
TL;DR: The data show that this polymorphism in PER3 predicts individual differences in the sleep-loss-induced decrement in performance and that this differential susceptibility may be mediated by its effects on sleep homeostasis.
Journal ArticleDOI
Blue-enriched white light in the workplace improves self-reported alertness, performance and sleep quality.
TL;DR: Exposure to blue-enriched white light during daytime workhours improves subjective alertness, performance, and evening fatigue.
Journal ArticleDOI
PER3 polymorphism and cardiac autonomic control : effects of sleep debt and circadian phase
TL;DR: The PER3 polymorphism affects the sympathovagal balance in cardiac control in NREM sleep similar to the effect of sleep deprivation.
Journal ArticleDOI
Sex differences and the effect of gaboxadol and zolpidem on EEG power spectra in NREM and REM sleep.
TL;DR: Sex dependent and differential effects of GBX and ZOL may be related to their differential affinity for GABA A receptor subtypes and their modulation by neurosteroids.
Journal ArticleDOI
Effect of a novel histamine subtype-3 receptor inverse agonist and modafinil on EEG power spectra during sleep deprivation and recovery sleep in male volunteers.
LM James,Robert Iannone,John Palcza,John J. Renger,Nicole Calder,Kristine Cerchio,Keith Gottesdiener,Richard Hargreaves,M. Gail Murphy,Julia Boyle,Derk-Jan Dijk +10 more
TL;DR: Both MK-0249 and modafinil exert effects on the EEG which are consistent with wake promotion, and no changes were observed for power spectra during sleep.
