In recent decades, increasing evidence has positioned slow-wave sleep (SWS) as a major
actor in neurophysiological phenomena such as glucose metabolism, hormone release …

During sleep, animals do not eat, reproduce or forage. Slee** animals are vulnerable to
predation. Yet, the persistence of sleep despite evolutionary pressures, and the deleterious …

While slee**, many vertebrate groups alternate between at least two sleep stages: rapid
eye movement and slow wave sleep,,–, in part characterized by wake-like and synchronous …

Chronic sleep deficiency, defined as a state of inadequate or mistimed sleep, is a growing
and underappreciated determinant of health status. Sleep deprivation contributes to a …

Sleep is a complex physiological process that is regulated globally, regionally, and locally
by both cellular and molecular mechanisms. It occurs to some extent in all animals, although …

During sleep, sensory stimuli rarely trigger a behavioral response or conscious perception.
However, it remains unclear whether sleep inhibits specific aspects of sensory processing …

The energy allocation (EA) model defines behavioral strategies that optimize the temporal
utilization of energy to maximize reproductive success. This model proposes that all species …

No current hypothesis can explain why animals need to sleep. Yet, sleep is universal, tightly
regulated, and cannot be deprived without deleterious consequences. This suggests that …

Sleep is often viewed as a vulnerable state that is incompatible with behaviours that nourish
and propagate species. This has led to the hypothesis that sleep has survived because it …

Sleep control is ascribed to a two-process model, a widely accepted concept that posits
homoeostatic drive and a circadian process as the major sleep-regulating factors. Cognitive …
