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, ...

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 ...

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 ...

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

Sleep hygiene refers to habits that support good-quality sleep. These include allowing enough time for sleep, keeping your ...

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 ...

The locus coeruleus is a region of the brain that is instrumental in coordinating our mental processing and is the primary source of noradrenaline in the brain, which acts to regulate arousal states ...
