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 ...

Researchers at the University of Lausanne have identified a novel role for the brain's "locus coeruleus" in sleep and its disruptions. This brain region facilitates the transition between NREM and REM ...

Sleep is one of the most widely studied states of consciousness, known to play a role in physical recovery, the processing of ...

New research reveals that neurons in the preoptic hypothalamus -- the region of the brain that regulates sleep and body temperature -- are rhythmically activated during non-rapid eye movement sleep ...

The noradrenergic locus coeruleus (LC) regulates arousal levels during wakefulness, but its role in sleep remains unclear. Here, we show in mice that fluctuating LC neuronal activity partitions ...

Researchers at the University of Lausanne have identified a novel role for the brain's 'locus coeruleus' in sleep and its disruptions. This brain region facilitates the transition between NREM and REM ...

Sleep is considered essential for the brain and body. A predominant concept is that sleep is regulated by circadian rhythmicity and sleep homeostasis, processes that were posited to be functionally ...

We all know that particular sleepy sensation that we feel when we are tired or after a long day. Were you aware that this is the beginning of a whole complex cycle in our brains? Once we close our ...

Non-rapid eye movement (NREM) parasomnias involve disordered sleep-related behaviors that occur during the first few hours of sleep. Common treatment options typically include medication and ...
