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 ...

Sleep can be divided into 2 phases — non-rapid eye movement (NREM) and rapid eye movement (REM) — and 4 stages that make a complete cycle. You’ll typically complete 4 to 6 cycles per night.

For more than 60 years, sleep researchers have known that there are two major categories of sleep: REM sleep, which stands for "rapid eye movement," and non-REM or non-rapid eye movement sleep ...

While it's well known that sleep enhances cognitive performance, the underlying neural mechanisms, particularly those related ...

During sleep, the body goes through multiple sleep cycles. Each cycle consists of four stages: three stages of non-rapid eye movement (non-REM) sleep and one stage of rapid eye movement (REM) sleep.

The rapid eye movement phase of sleep is associated with dreaming. Still, it remains unclear why rapid eye movements occur at that point. A study in mice provides one possible answer.

Rapid eye movement (REM) sleep brings about brief but periodic awakenings. In 1966, Dr. Frederick Snyder reported the "sentinel" function of REM could help animals prepare a fight or flight ...
