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, ...

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 ...

Research once viewed sleep as a passive state of “nothingness,” but modern neuroscience has revealed it to be a highly active, complex, and essential biological process. Far from being “down time,” ...

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 ...

Deep sleep refers to slow-wave sleep — a stage in the sleep cycle when brain waves slow down. Getting enough deep sleep is crucial for numerous bodily functions. But how to increase deep sleep isn’t ...
