What is slow wave sleep quizlet?

Slow-wave Sleep. sleep stages 3 and 4, whihc are accompainied by slow, deep breathing; a calm, regular heartbeat; and reduced blood pressure. Rapid Eye Movement (REM) Sleep.

During which stage of sleep can the brain be considered Alert quizlet?

we spend the longest time in the REM stage. REM sleep is marked by a return to fast, irregular EEG patterns similar to those of stage 1. the brain is so active during REM it looks like the person may be awake.

What is the function of REM sleep quizlet?

REM is characterized by rapid eye movements, more brain activity than other sleep stages, complete relaxation of the trunk muscles, irregular breathing and heart rate, penile erection or vaginal lubrication, and increased probability of vivid dreams. To determine REM sleep: Examine EEG patterns, and eye movements.

Is slow wave sleep the same as REM?

The principal characteristics during slow-wave sleep that contrast with REM sleep are moderate muscle tone, slow or absent eye movement, and lack of genital activity. Slow-wave sleep is considered important for memory consolidation. This is sometimes referred to as “sleep-dependent memory processing”.

Which brain region promotes slow wave sleep?

During baseline sleep, slow waves are most prevalent in frontal areas, and during recovery sleep following sleep deprivation, the frontal cortex is the area of the brain to show the greatest increase in SWA when compared with the central, parietal, and occipital regions.

What is the difference between slow-wave sleep and REM sleep?

Slow Wave Sleep (SWS), also known as deep sleep, is the time when your muscles repair and grow. During this stage the body produces 95% of its daily supply of growth hormones. REM sleep is when the brain is restored. It is at this time that ideas and skills acquired during the day are cemented as memories.

Which stage of sleep is characterized by slow and even brain waves and is most necessary for growth and rest quizlet?

stage 3 sleep :A sleep characterized by slow brain waves, with greater peaks and valleys in the wave pattern than in stage 2 sleep. stage 4 sleep: The deepest stage of sleep, during which we are least responsive to outside stimulation.

What are the 4 stages of sleep quizlet?

Terms in this set (6)

• Stage 1. transition from wakefulness and sleep. Lasts 1-7 minutes.
• Stage 2. Beginning of sleep, high frequency bursts of brain activity called Sleep Spindles.
• Stage 3. Deep Sleep.
• Stage 4. Deep Sleep.
• Non-REM Sleep. where you spend 80% of your sleep time.
• REM Sleep. 205 of your sleep time.

What is REM sleep in psychology quizlet?

REM Sleep. rapid eye movement sleep, a recurring sleep stage during which vivid dreams commonly occur. Also known as paradoxical sleep, because the muscles are relaxed (except for minor twitches) but other body systems are active.

Which brain region promotes slow-wave sleep?

What is a slow wave sleep?

Slow-wave sleep is characterized by brain wave patterns ( electroencephalogram or EEG) with a frequency of less than 4 Hz and peak-to-peak amplitude of 75 microV. Tired of Psoriasis?

What is slow wave sleep (SWS)?

Slow-wave sleep (SWS) is an active phenomenon probably brought about by the activation of serotonergic neurons of the raphe system. The slow wave seen in the cortical EEG is generated through thalamocortical communication through the thalamocortical neurones.

What is slow wave sleep stage?

Slow-wave sleep (SWS), often referred to as deep sleep, consists of stage three (combined stages 3 and 4) of non-rapid eye movement sleep. Initially, SWS consisted of both Stage 3 (N3), which has 20-50 percent delta wave activity, and Stage four (N4), which has more than 50 percent delta wave activity.

What is a slow wave sleep disorder?

There are several sleep disorders and parasomnias that occur predominantly during slow-wave sleep. Sleepwalking (Somnambulism), night terrors (sleep terrors), bed-wetting (Enuresis), sexsomnia, and sleep eating are all associated with slow-wave sleep.
