The daily alternation between sleep and wakefulness is one of the most dominant features
of our lives and is a manifestation of the intrinsic 24 h rhythmicity underlying almost every …

Sleep timing is controlled by the subtle interplay between circadian and homeostatic
oscillators which, according to their endogenous properties, allow beings to feel …

Sleep reactivity is the trait‐like degree to which stress exposure disrupts sleep, resulting in
difficulty falling and staying asleep. Individuals with highly reactive sleep systems …

The circadian rhythm is crucial for physiological and behavioral functions. Chronotype,
which represents individual preferences for activity and performance, is associated with …

At the core of human thought, for the majority of individuals in the developed nations at least,
there is the tacit assumption that as a species we are unfettered by the demands imposed by …

The circadian clock is an evolutionarily highly conserved endogenous timing program that
structures physiology and behavior according to the time of day. Disruption of circadian …

Light around twilight provides the primary entrainment signal for circadian rhythms. Here we
review the mechanisms and responses of the mouse and human circadian systems to light …

The importance of time is ever prevalent in our world, and disruptions to the normal
light/dark and sleep/wake cycle have now become the norm rather than the exception for a …

Aim Symptoms of bipolar disorder (BD) include changes in mood, activity, energy, sleep,
and appetite. Since many of these processes are regulated by circadian function, circadian …

Chronotype can be defined as an expression or proxy for circadian rhythms of varied
mechanisms, for example in body temperature, cortisol secretion, cognitive functions, eating …
