Brain activity during sleep is characterized by circuit-specific oscillations, including slow
waves, spindles and theta waves, which are nested in thalamocortical or hippocampal …

In most healthy people morning awakening is associated with a burst of cortisol secretion:
the cortisol awakening response (CAR). It is argued that the CAR is subject to a range …

The modern understanding of sleep is based on the classification of sleep into stages
defined by their electroencephalography (EEG) signatures, but the underlying brain …

Highlights•Slow waves of NREM sleep can occur locally and asynchronously across brain
regions.•Their regional distribution and amplitude is in part mediated by experience …

Sleep inertia, or the grogginess felt upon awakening, is associated with significant cognitive
performance decrements that dissipate as time awake increases. This impairment in …

The transition from sleep to wake is marked by sleep inertia, a distinct state that is
measurably different from wakefulness and manifests as performance impairments and …

The crucial role of sleep in physical and mental health is well known, especially during the
developmental period. In recent years, there has been a growing interest in examining the …

In healthy individuals, the majority of cortisol secretion occurs within several hours
surrounding morning awakening. A highly studied component of this secretory period is the …

OBJECTIVES: Sleep and vigilance disorders are among the most commonly reported
symptoms following a concussion. The aim of the study was thus to investigate the effects of …

Sleep is traditionally considered a global process involving the whole brain. However,
recent studies have shown that sleep depth is not evenly distributed within the brain. Sleep …
