Functional connectivity during rested wakefulness predicts vulnerability to sleep deprivation
Significant inter-individual differences in vigilance decline following sleep deprivation exist. We characterized functional connectivity in 68 healthy young adult participants in rested wakefulness and following a night of total sleep deprivation. After whole brain signal regression, functionally connected cortical networks during the well-rested state exhibited reduced correlation following s...
متن کاملPER3 Polymorphism Predicts Sleep Structure and Waking Performance
Circadian rhythmicity and sleep homeostasis interact to regulate sleep-wake cycles [1-4], but the genetic basis of individual differences in sleep-wake regulation remains largely unknown [5]. PERIOD genes are thought to contribute to individual differences in sleep timing by affecting circadian rhythmicity [6], but not sleep homeostasis [7, 8]. We quantified the contribution of a variable-numbe...
متن کاملHabitual short sleep duration and circulating endothelial progenitor cells
Chronic short sleep duration has been linked to endothelial dysfunction and increased risk of cardiovascular disease. Circulating endothelial progenitor cells (EPCs) are vital to endogenous vascular repair processes and cardiovascular health. We tested the hypothesis that habitual short sleep duration is associated with impairment in EPC number and function. Cells with phenotypic EPC characteri...
متن کاملThe association between habitual sleep duration and sleep quality in older adults according to health status.
BACKGROUND research on the association between habitual sleep duration and quality in older adults is scarce and has shown conflicting results. Moreover, no previous study has assessed the influence of health status on this association. OBJECTIVES to examine the association between habitual duration and quality of sleep in older adults, and to test if this association varies with health statu...
متن کاملHabitual Sleep Duration, Unmet Sleep Need, and Excessive Daytime Sleepiness in Korean Adults
BACKGROUND AND PURPOSE Sleep need differs between individuals, and so the same duration of sleep will lead to sleep insufficiency in some individuals but not others. The aim of this study was to determine the separate and combined associations of both sleep duration and unmet sleep need with excessive daytime sleepiness (EDS) in Korean adults. METHODS The participants comprised 2,769 Korean a...
