Your psychology instructor mentioned that during a night of sleep, a person goes through cycles of light and deep sleep, while also experiencing dreams. Using a description of the stages of NREM and REM, describe a night of sleep. When you lay down at night after a long hard day, you probably think that your sleeping patterns are going to be different every night depending on what you did that day. But that’s not entirely true, sleep actually follows a pretty predictable pattern each night. Each cycle of sleep lasts about ninety minutes and contains four different stages. The type that we experience in all four stages is called NREM (non-rapid eye movement). When you are in this type of sleep, your body experiences a lot of things. In this type of sleep our heart and respiration rates are steady and slow, movements are minimal, and our brain activity and blood pressure are at their lowest in the 24-hour period. As you can see, our bodies experience a lot of things while we are asleep. It’s amazing that we aren’t even aware of it. NREM occurs in all four stages of sleep. In stage one, irregular waves with some alpha waves occur along with transition from waking to sleeping. In stage two we transfer from light to deeper sleep and experience sleep spindles which are waves with alternating periods of calm and flashes of intense activity appear. Stage three consists of deeper sleep and contains slow wave sleep, which happens when EEG shows 20% of brain waves. The final and fourth stage contains the deepest sleep and begins when 50% of waves are delta waves. After about 40 minutes of being in stage 4 sleep, delta waves begin to disappear. When that occurs, we go back through stage 3 sleep and stage two until we get back to stage 1 sleep again. As we go back into stage 1, our pathway through the night drifts into REM (rapid eye movement) sleep. During this time, our brains are highly active. Epinephrine
being NREM sleep, and the second being REM sleep. NREM is an acronym that stands for “Non Rapid Eye Movement” and REM is “Rapid Eye Movement.” NREM sleep is often referred to as “quiet sleep” because during the stages of NREM sleep, the heart slows down, breathing becomes fainter, the body has little to no movement, and your blood pressure and brain activity gradually decrease. However, NREM sleep is not the sleep that you usually get or need. You can still be easily woken up while under NREM sleep…
The two main phases of sleep are rapid eye movement (REM) and non-rapid eye movement (NREM). Sleep begins in the phase known as NREM sleep. The first stage of NREM sleep begins with the feeling of “drifting off”. Stage two of NREM sleep involves a change in brain wave patterns. The third and fourth stages of NREM sleep are the deepest levels of sleep. Sleep terrors, sleep walking, and bedwetting episodes generally occur within stage four of NREM sleep (Hanrahan, 2006).

will suggest theories that go some way in helping us understand the function of sleep. I will address the potential for future understanding created by fully understanding the key differences between non rapid eye movement sleep (NREM) and rapid eye movement sleep (REM) and suggest that our need for these two distinct states must an indication of one of the key roles of sleep. Other considerations to be examined are that sleep has been shown to replenish and saves energy, render us inactive at opportune…
wanting to get up in the morning, many people feel sleepy or “zone out” on a daily basis. These types of feelings bring up the importance of sleep and the powerful need for sleep. In fact, there are two types of sleep: rapid eye movement (REM) and non-REM (NREM) sleep.
Neurotransmitters are nerve signaling transmitters that control whether we are asleep or awake, which act on different group of neurons in the brain. Neurons in the brainstem, which connects the brain with the spinal cord, produce…
sleep known as the rapid eye movement (REM) sleep. Our sleep cycle occurs in a multi-stage format in which there are five stages altogether. The first four stages of sleep are that of non-rapid eye movement (NREM) while the fifth stage occurs in REM sleep. Nightmares are dream experiences of a frightening nature, occurring usually in the second half of the night, in a REM sleep stage, and ending with them waking up. Usually when a person wakes from this type of REM nightmare they are oriented and aware…
(10 seconds-2 minutes). Occurs during REM or NREM. Bruxism- clenching and grinding of teeth. Occurs during stage II NREM sleep. Enuresis- Bed-wetting during sleep. Occurs in children over 3 years in NREM stages 3 and 4. Periodic limb movements- legs jerk twice or three times per minute in sleep. Mostly due to restless leg syndrome. Sleep taling- talking during sleep. Occurs in NREM before REM sleep. Somnambulism- sleepwalking. Occurs in stage 3 and 4 of NREM sleep, 1 to 2hrs after falling asleep…
rapid-eye-movement (REM) sleep and non-REM sleep (NREM). Cycling through all of the sleep stages for an adequate amount of time is essential to being fully rested”. NREM sleep consists of four stages that range from drowsiness to deep sleep. In the early stages (I and II), individuals awake easily and may not even realize that they have been sleeping. In the deeper stages (III and IV), waking is difficult. When awakened, individuals in stages III and IV may feel disoriented and confused. In NREM sleep their…
