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 ...

The restorative effects of sleep on the brain are well known, but what happens at the neural level remains a fascinating mystery. A groundbreaking study led by researchers from Rice University, ...

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 ...

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 ...

Non-rapid eye movement (NREM) sleep arousal disorders involve repeated episodes of incomplete awakening from sleep, most commonly sleepwalking or night terrors (also known as sleep terrors), but ...

REM, also known as Rapid Eye Movement is where most dreaming occurs, brain activity increases, and the body becomes ...

A new study shows that even a moderate dose of caffeine alters brain activity during sleep, increasing complexity and nudging neural systems toward a high-efficiency processing state, especially in ...

Sleep is a universal biological state that allows all animals, from mammals to amphibians, fish and even insects, to restore ...
