Sleep is essential for both cognition and maintenance of healthy brain function. Slow waves
in neural activity contribute to memory consolidation, whereas cerebrospinal fluid (CSF) …

Sleep is essential for brain function in a surprisingly diverse set of ways. In the short term,
lack of sleep leads to impaired memory and attention; in the longer term, it produces …

Sleep is crucial for healthy cognition, including memory. The two main phases of sleep, REM
(rapid eye movement) and non-REM sleep, are associated with characteristic …

The conservation of sleep across all animal species suggests that sleep serves a vital
function. We here report that sleep has a critical function in ensuring metabolic homeostasis …

When we fall asleep, consciousness fades yet the brain remains active. Why is this so? To
investigate whether changes in cortical information transmission play a role, we used …

Since the discovery of rapid eye movement (REM) sleep, the nature of the eye movements
that characterize this sleep phase has remained elusive. Do they reveal gaze shifts in the …

Different global patterns of brain activity are associated with distinct arousal and behavioral
states of an animal, but how the brain rapidly switches between different states remains …

Sleep is characterized by synchronized events in billions of synaptically coupled neurons in
thalamocortical systems. The activation of a series of neuromodulatory transmitter systems …

The proposed mechanisms of sleep-dependent memory consolidation involve the overnight
regulation of neural activity at both synaptic and whole-network levels. Now, there is a lack …

Slow-wave sleep consists in slowly recurring waves that are associated with a large-scale
spatio-temporal synchrony across neocortex. These slow-wave complexes alternate with …
