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

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 ...

Have you ever jolted awake in the middle of the night, heart racing, drenched in sweat, with no memory of what happened?

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 ...
