The homeostatic regulation of sleep manifests as a relative constancy of its total daily
amount, and the compensation of sleep loss by an increase in its subsequent duration and …

Sleep homeostasis manifests as a relative constancy of its daily amount and intensity.
Theoretical descriptions define 'Process S', a variable with dynamics dependent on global …

Sleep is a fundamental homeostatic process within the animal kingdom. Although various
brain areas and cell types are involved in the regulation of the sleep–wake cycle, it is still …

Sleep is a daily experience across humans and other species, yet our understanding of how
and why we sleep is presently incomplete. This is particularly prevalent in research …

Sleep states are universally described throughout the animal kingdom, yet our
understanding of their contribution to brain function and dysfunction remains limited …

Although mammals of different species have different sleep patterns, brief sleep–wake
transitions commonly are observed across species and appear to occur randomly …

Increasing time spent awake results in accumulated sleep need, a process known as sleep
homeostasis. Sleep homeostasis combines with a 24 h circadian rhythm to determine when …

Wakefulness, non-rapid eye-movement (NREM) and rapid eye-movement (REM) sleep differ
from each other along three dimensions: behavioral, phenomenological, physiological …

All our lives, we alternate between wakefulness and sleep with direct consequences on our
ability to interact with our environment, the dynamics and contents of our subjective …

Animals continuously alternate between sleep and wake states throughout their life. The
daily organization of sleep and wakefulness is orchestrated by circadian, homeostatic, and …
