Which of the Following Is a Characteristic of Rem Sleep

- April 17, 2022

NREM sleep is divided into stages 1 2 3 and 4 representing a continuum of relative depth. The two main types of sleep are rapid-eye-movement REM sleep and non-rapid-eye-movement NREM sleep.

Circadian rhythms the daily rhythms in physiology and behavior regulate the.

. Each has unique characteristics including variations in brain wave patterns eye movements and muscle tone. In these stages brain activity transitions to delta waves which are the lowest in frequency and highest in amplitude. However random short bursts of increased frequency called sleep spindles are a defining characteristic of this stage.

It is most difficult to awaken people from slow-wave sleep. Many sleep experts think that these eye movements. These four sleep stages are called non-rapid eye movement non-REM sleep and its most prominent feature is the slow-wave stage IV sleep.

Stage three and four are very similar and together are considered to be deep sleep. Especially during non-REM sleep the brain uses significantly less energy during sleep than it. On an EEG REM sleep often called active sleep is identifiable by its characteristic low-amplitude small high-frequency fast waves and alpha rhythm as well as the eye movements for which it is named.

These two stages combined. REM sleep is considered closer to wakefulness and is characterized by rapid eye movement and muscle atonia. Hence it is considered to be the deepest stage of sleep.

Stage two also contains theta waves. Following a period of slow-wave sleep however EEG recordings show that the stages of sleep reverse to reach a. There are two types of sleep non-rapid eye movement sleep and rapid eye movement sleep.

NREM is considered to be deep sleep the deepest part of NREM is called slow wave sleep and is characterized by lack of prominent eye movement or muscle paralysis.
