Sleep deprivation among adolescents is epidemic. We argue that this sleep deprivation is
due in part to pubertal changes in the homeostatic and circadian regulation of sleep. These …

Virtually every eukaryotic cell has an endogenous circadian clock and a biological sex.
These cell-based clocks have been conceptualized as oscillators whose phase can be reset …

Circadian (daily) rhythms are present in almost all plants and animals. In mammals, a brain
clock located in the hypothalamic suprachiasmatic nucleus maintains synchrony between …

While much is known about the mechanisms that underlie sleep and circadian rhythms, the
investigation into sex differences and gonadal steroid modulation of sleep and biological …

Circadian rhythms and “clock gene” expression are involved in successful reproductive
cycles, mating, and pregnancy. Alterations or disruptions of biological rhythms, as commonly …

Alzheimer's disease (AD) is a devastating neurodegenerative condition associated with
severe cognitive and behavioral impairments. Circadian rhythms are recurring cycles that …

Determining the cause of psychiatric disorders is a goal of modern neuroscience, and will
hopefully lead to the discovery of treatments to either prevent or alleviate the suffering …

Background: Night-shift work, exposure to artificial light-at-night (ALAN) and particularly blue
light spectrum, and the consequent circadian disruption may increase the risk of breast and …

Scientists, public health and school officials are paying growing attention to the mechanism
underlying the delayed sleep patterns common in human adolescents. Data suggest that a …

Physiological processes and behaviors in many mammals are rhythmic. Recently there has
been increasing interest in the role of circadian rhythmicity in the control of reproductive …
