During REM (Rapid Eye Movement) sleep, the brain releases several neurotransmitters, with acetylcholine being the most prominent. Acetylcholine plays a crucial role in promoting REM sleep and is associated with the regulation of various sleep functions, including memory consolidation and dreaming. Additionally, other neurotransmitters like serotonin and norepinephrine are typically suppressed during this phase, contributing to the unique characteristics of REM sleep.

Sleep spindles appear during what stage?
Sleep spindles typically appear during stage 2 of non-REM sleep. They are brief bursts of brain activity that help in the consolidation of memories and are associated with the transition from light to deeper sleep.
How many hours of REM sleep do humans get a night?
About 1 hour and 30 minutes. Unless you follow (something like) the Uberman Sleep Shedule. In that case you can get 6 times 20 minutes of REM sleep, distributed over 24 hours (so 2 hours in total).
What are the names of the stages of sleep?
During sleep, we usually pass through five phases of sleep. These stages progress in a cycle from stage 1 to rapid-eye-movement (REM) sleep, then the cycle starts over again with stage 1. We spend almost 50 percent of our total sleep time in stage 2 sleep, about 20 percent in REM sleep, and the remaining 30 percent in the other stages. Infants, by contrast, spend about half of their sleep time in REM sleep. During stage 1, which is light sleep, we drift in and out of sleep and can be awakened easily. Our eyes move very slowly and muscle activity slows. People awakened from stage 1 sleep often remember fragmented visual images. Many also experience sudden muscle contractions called hypnic myoclonia, often preceded by a sensation of starting to fall. These sudden movements are similar to the "jump" we make when startled. When we enter stage 2 sleep, our eye movements stop and our brain waves (fluctuations of electrical activity that can be measured by electrodes) become slower, with occasional bursts of rapid waves called sleep spindles. In stage 3, extremely slow brain waves called delta waves begin to appear, interspersed with smaller, faster waves. By stage 4, the brain produces delta waves almost exclusively. It is very difficult to wake someone during stages 3 and 4, which together are called deep sleep. There is no eye movement or muscle activity. People awakened during deep sleep do not adjust immediately and often feel groggy and disoriented for several minutes after they wake up. Some children experience bedwetting, night terrors, or sleepwalking during deep sleep. When we switch into REM sleep, our breathing becomes more rapid, irregular, and shallow, our eyes jerk rapidly in various directions, and our limb muscles become temporarily paralyzed. Our heart rate increases, our blood pressure rises, and males develop penile erections. When people awaken during REM sleep, they often describe bizarre and illogical tales - dreams. The first REM sleep period usually occurs about 70 to 90 minutes after we fall asleep. A complete sleep cycle takes 90 to 110 minutes on average. The first sleep cycles each night contain relatively short REM periods and long periods of deep sleep. As the night progresses, REM sleep periods increase in length while deep sleep decreases. By morning, people spend nearly all their sleep time in stages 1, 2, and REM. People awakened after sleeping more than a few minutes are usually unable to recall the last few minutes before they fell asleep. This sleep-related form of amnesia is the reason people often forget telephone calls or conversations they've had in the middle of the night. It also explains why we often do not remember our alarms ringing in the morning if we go right back to sleep after turning them off1.1. http://healthjournal.upmc.com/0205/SleepPhases.htm
What does the abbreviation REM stand for in sleep research?
Restless eye movement
What part of the brain affects sleep dreams and respiration?
The brainstem, specifically the pons and medulla oblongata, play a crucial role in regulating respiration during sleep. The limbic system and prefrontal cortex are involved in the generation and processing of dreams during the rapid eye movement (REM) stage of sleep.
Which statement about REM sleep is incorrect?
During REM sleep, people seldom dream.
What does not occur during a narcoleptic sleep episode?
Truly "deep" sleep does not occur during REM sleep. REM sleep is when you are dreaming. It is deeper than light sleep, but not as far down in unconsciousness as "deep" sleep.
Can you move during rem sleep?
Yes, it is possible to move during REM (rapid eye movement) sleep. While most muscles are generally paralyzed during REM sleep to prevent acting out dreams, some people may experience a condition called REM sleep behavior disorder (RBD) where this paralysis is incomplete, leading to movements or even violent behaviors during REM sleep.
What stage is REM sleep?
REM is during stage 3 and 4 where most of the dreaming occurs.
Why do your eyes move in REM sleep?
It is caused by the dreams during sleep
Do the eye balls roll when asleep?
Yes, several times each sleeping period. the movement of the eyes during sleep is called REM [Rapid Eye Movement) The periods of sleep during which REM occurs is called REM sleep.
During REM sleep a person is dreaming?
True.
If muscles are in state of near-paralysis during REM sleep then how is sleepwalking possible?
Sleepwalking usually only occurs during stage 3 of non-rem sleep.
Do you blink in are sleep?
Yes, your eyes move constantly and a lot during the REM phase of sleep. REM stands for Rapid Eye Movement.
Is rem sleep deep?
3/13/2012 jhh: REM sleep is NOT deep sleep. In fact, it is the lightest stage of sleep. In order from awake to deep sleep: AWAKE, REM, LIGHT, DEEP. Deep sleep and REM sleep are the most important stages though. Light sleep doesn't do much for you. Deep replenishes your body, while REM replenishes your mind. Older answer (not accurate): Yes. It is the deeper form of sleep that we experience during our sleep cycle, rem sleep is where dreaming occurs But not the deepest sleep, which would be delta. That's where, unless your a mother and hear your baby cry, you are oblivious to your environment.
During REM sleep?
Sleep is prompted by natural cycles of activity in the brain and consists of two basic states: rapid eye movement (REM) sleep and non-rapid eye movement (NREM) sleep, which consists of Stages 1 through 4. During sleep, the body cycles between non-REM and REM sleep. Typically, people begin the sleep cycle with a period of non-REM sleep followed by a very short period of REM sleep. Dreams generally occur in the REM stage of sleep. Then the cycle repeats all over again.
The bulk of people's dreams occurs during what?
rem sleep
