Over more than a century of research has established the fact that sleep benefits the
retention of memory. In this review we aim to comprehensively cover the field of “sleep and …

According to the two-process model of sleep regulation, the timing and structure of sleep are
determined by the interaction of a homeostatic and a circadian process. The original …

A commonly held view is that extended wakefulness is causal for a broad spectrum of
deleterious effects at molecular, cellular, network, physiological, psychological, and …

Abstract Study Objective: Sleep slow-wave activity (SWA, EEG power between 0.5 and 4.0
Hz) decreases homeostatically in the course of non-rapid eye movement sleep (NREM) …

Previous work showed that two types of slow waves are temporally dissociated during the
transition to sleep: widespread, large and steep slow waves predominate early in the falling …

Abstract Study Objectives Insomnia is common in older adults, and is associated with poor
health, including cognitive impairment and cardio-metabolic disease. Although the …

The electrical activity of the brain does not only reflect the current level of arousal, ongoing
behavior, or involvement in a specific task but is also influenced by what kind of activity, and …

Two dramatic phenomena of human adolescence are sexual maturation and a steep decline
in the delta EEG of non-rapid eye movement (NREM) sleep. It has long been speculated that …

In this paper we reviewed results of sleep research that have changed the views about sleep
slow wave homeostasis, which involve use-dependent and experience-dependent local …

Summary Slow oscillations (< 1 Hz) in the non‐rapid eye movement (NREM) sleep
electroencephalogram (EEG) result from slow membrane potential fluctuations of cortical …
