Since ancient times it is known that melancholia and sleep disturbances co-occur. The
introduction of polysomnography into psychiatric research confirmed a disturbance of sleep …

Neural activity and behavior are both notoriously variable, with responses differing widely
between repeated presentation of identical stimuli or trials. Recent results in humans and …

The glymphatic system is a network of perivascular spaces that promotes movement of
cerebrospinal fluid (CSF) into the brain and clearance of metabolic waste. This fluid …

Memory consolidation during sleep is thought to depend on the coordinated interplay
between cortical slow waves, thalamocortical sleep spindles and hippocampal ripples, but …

Extended wakefulness is associated with reduced performance and the build-up of sleep
pressure. In the cortex, this manifests as changes in network activity. These changes show …

Vigilant attention is a major component of a wide range of cognitive performance tasks.
Vigilant attention is impaired by sleep deprivation and restored after rest breaks and (more …

The claustrum has been linked to attention and sleep. We hypothesized that this reflects a
shared function, determining responsiveness to stimuli, which spans the axis of …

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

Abstract Slow waves (0.5–4 Hz) predominate in the cortical electroencephalogram during
non-rapid eye movement (NREM) sleep in mammals. They reflect the synchronization of …

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