Interaction of Chronic Sleep Restriction and Circadian Misalignment on Sleep and Neuro-Cognitive Performance

The primary objectives of the proposed experimental and modeling efforts are to quantify the influences of acute sleep deprivation (short-term homeostatic), chronic sleep restriction (long...

Impact of a Sleep Debt in Middle-Aged and Older Adults

This project has 6 aims. 1. To examine the impact of recurrent partial sleep loss in young, middle-aged and older men and women. Sleep will be restricted to 4 hours. 2. To...

Circadian Misalignment and Energy Balance

Preliminary findings from the investigators' lab suggest that circadian misalignment, occurring when meals and sleep are mistimed from one another, alters resting state neuronal processing...

Sleep Disruption Induced Impairments in Bone Formation

This is a small intervention study with healthy males aged 20-65 years old who habitually sleep 7-9 hours/night.This study investigates if and how sleep restriction, independent of circadi...

Circadian Misalignment and Insulin Sensitivity

This study will evaluate the effect of circadian misalignment on insulin sensitivity in healthy lean subjects in a randomized cross-over design. Subjects will be admitted to the research f...

Sleep spindles in adolescence: a comparison across sleep restriction and sleep extension.

The tendency for adolescents to have restricted sleep has been examined in numerous studies; however, the impact of sleep restriction on adolescents' neural activity during sleep (measured by electroe...

Presence of small screens in bedrooms is associated with shorter sleep duration and later bedtimes in children with obesity.

The presence of small screens in the sleep environment has been associated with shorter sleep duration and later bedtimes in children of normal weight, but the role these devices play in the sleep env...

Circadian and Sleep Circuits Ring Together.

Prolonged wakefulness stimulates the homeostatic need to sleep, but transition to sleep also depends on the circadian time of day. However, links between circadian and homeostatic influences are not w...

Misaligned core body temperature rhythms impact cognitive performance of hospital shift work nurses.

Circadian rhythms greatly influence 24-h variation in cognition in nearly all organisms, including humans. Circadian clock impairment and sleep disruption are detrimental to hippocampus-dependent memo...

Clinical significance of social jetlag in patients with excessive daytime sleepiness.

Social jetlag has recently attracted attention as the circadian misalignment between biological and social clocks. We aimed to examine social jetlag and its effect on daytime sleepiness and daily func...

Medical and Biotech [MESH] Definitions

Abnormal sleep-wake schedule or pattern associated with the CIRCADIAN RHYTHM which affect the length, timing, and/or rigidity of the sleep-wake cycle relative to the day-night cycle.

Dyssomnias associated with disruption of the normal 24 hour sleep wake cycle secondary to travel (e.g., JET LAG SYNDROME), shift work, or other causes.

A broad category of sleep disorders characterized by either hypersomnolence or insomnia. The three major subcategories include intrinsic (i.e., arising from within the body) (SLEEP DISORDERS, INTRINSIC), extrinsic (secondary to environmental conditions or various pathologic conditions), and disturbances of circadian rhythm. (From Thorpy, Sleep Disorders Medicine, 1994, p187)

A nonapeptide that is found in neurons, peripheral organs, and plasma. This neuropeptide induces mainly delta sleep in mammals. In addition to sleep, the peptide has been observed to affect electrophysiological activity, neurotransmitter levels in the brain, circadian and locomotor patterns, hormonal levels, psychological performance, and the activity of neuropharmacological drugs including their withdrawal.

Periods of sleep manifested by changes in EEG activity and certain behavioral correlates; includes Stage 1: sleep onset, drowsy sleep; Stage 2: light sleep; Stages 3 and 4: delta sleep, light sleep, deep sleep, telencephalic sleep.
