Why is REM sleep sometimes called paradoxical sleep quizlet?
REM sleep is also referred to as paradoxical sleep because while the brain and other body systems become more active, muscles become more relaxed. Dreaming occurs due to increased brain activity, but voluntary muscles become immobilized.
Which of the following is characteristic of REM sleep quizlet?
REM brain waves have fast frequency and low amplitude and look very similar to beta waves, which occur when you are wide-awake. During this stage your body is physiologically aroused, but your voluntary muscles are paralyzed. REM sleep stage is highly associated with dreaming.
Which term is also used to refer to Paradoxic sleep?
Rapid eye movement (REM) sleep is called paradoxical sleep because it involves seemingly contradictory states of an active mind and a sleeping body.
What are the relatively slow brain waves of a relaxed awake state called?
AP Psychology – Unit 5 Vocabulary Review
| A | B |
|---|---|
| alpha waves | the relatively slow brain waves of a relaxed, awake state. |
| sleep | periodic, natural loss of consciousness—as distinct from unconsciousness resulting from a coma, general anesthesia, or hibernation. |
Why is REM sleep called a paradoxical sleep provide an example to illustrate this?
Therefore, no movement of voluntary muscles occurs during REM sleep in a normal individual; REM sleep is often referred to as paradoxical sleep because of this combination of high brain activity and lack of muscle tone.
What is paradoxical about paradoxical sleep quizlet?
Paradoxical sleep is paradoxical (“apparently self-contradictory”) because it is deep sleep in some ways(relaxed muscles) and light(high brain activity) in others. Researchers use the term REM sleep when referring to humans, but often prefer the term paradoxical sleep for non human species that lack eye movement.
Why was REM sleep as paradoxical sleep at the same time?
REM sleep is coined “paradoxical” because of its similarities to wakefulness. Although the body is paralyzed, the brain acts as if it is somewhat awake, with cerebral neurons firing with the same overall intensity as in wakefulness.
What brain waves are in REM sleep?
Delta waves are associated with the deep sleep stages: stage 3 and REM. During stage 3, less than half of brain waves consist of delta waves, while more than half of brain activity consists of delta waves during REM sleep.
Which brain waves are associated with being awake and alert?
Just below gamma waves on the spectrum are the beta waves. These waves fall into the 12-38 Hz range. These are the brain waves that dominate when you’re awake, alert, and engaged. You can have relatively faster or “high beta” waves, which occur when you’re involved in very complex thought processes.
What causes paradoxical sleep?
In 55% of people, the cause is unknown, and in 45%, it’s linked with alcohol or sedative-hypnotic withdrawal, tricyclic antidepressant (such as imipramine), or serotonin reuptake inhibitor use (such as fluoxetine, sertraline, or paroxetine) or other types of antidepressants (mirtazapine).
Which of the following best explains why REM sleep is paradoxical?
Why is REM sleep sometimes called “paradoxical sleep”? The brain is very active even though the body is very inactive.
Why is it called REM sleep?
REM sleep was first discovered in the 1950s, when scientists studying sleeping infants noticed that there were distinct periods when their eyes moved rapidly from side to side. These rapid eye movements, or REMs, earned REM sleep its name.
What waves are seen during REM sleep?
Indeed, they distinguished two groups of delta waves occurring during REM sleep: slower (<2 Hz) waves, recorded in medial-occipital regions, present in both NREM and REM sleep, and faster (2.5–3 Hz), REM-sleep-exclusive, fronto-central/occipito-temporal “sawtooth” waves.
Why is REM sleep called paradoxical sleep hint A paradox is a contradiction?
Paradox and Pajamas Paradoxical sleep is another term for the REM stage of the sleep cycle. It is paradoxical because it is characterized by body paralysis and high-frequency brain activity. This allows us to dream deeply and perhaps absurdly without acting out on our dreams.
What happens during paradoxical sleep?
Paradoxical is a word that may be overused in the realm of sleep medicine: it applies to a sleep state, an experience of insomnia characterized by sleep state misperception, and even a behavioral treatment for insomnia. 1 Paradoxical sleep is also known as the rapid eye movement (REM) stage of sleep.
What means REM sleep?
The phase of sleep in which most dreams occur. During REM sleep, a person’s brain activity, breathing, heart rate, and blood pressure increase, and the eyes move rapidly while closed.
