During tactile perception, long-range intracortical top-down axonal projections are essential for processing sensory information. Whether these projections regulate sleep-dependent long-term memory ...

While it's well known that sleep enhances cognitive performance, the underlying neural mechanisms, particularly those related to nonrapid eye movement (NREM) sleep, remain largely unexplored. A new ...

A restful night alternates in cycles between non-rapid eye movement (NREM) and rapid eye movement (REM) sleep states. The study from UNIL shows that a brain region called the "locus coeruleus" (in ...

What triggers the mammalian sleep cycle's shift between non-rapid eye movement (NREM) and rapid eye movement (REM) sleep? A new study in mice suggests increased levels of dopamine in a key region of ...

Researchers identified neurons that promote non-REM sleep in the brainstem in mice. These neurons commonly expressed the gene that encodes the neuropeptide neurotensin. Activation of these neurons ...

These statistics help us understand why sleep is crucial to our health and reveal how extensive sleep issues are nationwide. Ashlee is an MBA business professional by day and a dynamic freelance ...

The average person spends around a third of their life sleeping. Yet as many as 70 million Americans suffer from chronic sleep disorders and wakefulness, studies have found, and tossing and turning at ...

A fascinating new study from scientists at UC Berkeley has homed in on exactly which phase of sleep seems to best keep anxiety levels in check. The research both affirms a causal association between ...

Sneezing is a reflex that helps expel pollen, dust, and other irritants from your nasal passages. Your brain prevents reflexes in NREM sleep and muscle movements in REM sleep, so you can't sneeze.

Research suggests that both REM (rapid eye movement) and NREM (non-rapid eye movement) stages in the sleep cycle are ...
