Rapid Eye Movement Research Paper

Then you will move into stage two which includes sleep spindles and K complexes. Sleep spindles are very short bursts of brain activity, and K complexes are single high voltage strikes of brain activity. Also, in stage two delta brain waves start to slow function of the brain preparing for stage three and four. Stage three and stage four i will talk about as one because they are very similar and do similar things. These stages are referred to slow wave sleep because your brain is in it’s slowest speed of function. In stage three you brain is between 20 and 50 percent delta waves, from 50 to 100 percent delta waves you are considered to be in stage four. While in stage four people may experience sleep walking and other muscular movement without knowing so. Noises as loud as 90 decibels may not be able to wake the person from sleep. During REM sleep which is after NREM sleep the brain is more active and alert. This is where most dreams occur because your brain is active but you are still sleeping. After the short 15 minute period of REM sleep you will start over with stage one of NREM these cycles normally take 90 minutes to complete. Activity during sleep can come at any point but is most common in REM or stage four of

This stage does last longer than the previous one but only by 10 more minutes. In Non-REM 2, you have this weird and fascinating action happing in your noggin know as sleep spindles. These sleep spindles are bursts of rapid, rhythmic brain-wave activity. After this stage comes one of the best parts of sleep and the part that you’ll generally wake up covered in drool in. This happens to be Non-REM 3 which is often categorized as deep sleep. In this particular stage, we are welcomed by slow delta waves that our brain emits. When this stage has had it’s time to shine, which is 30 minutes, it is time to move onto the final

While experiencing good sleep, I will unconsciously pass through five stages: 1, 2, 3, 4 and REM sleep (citation). According to the PL100 text, these stages progress cyclically from 1 through REM then begin again with stage 1, and usually,

These stages are characterized by bursts of electrical activity on electroencephalogram (EEG) recordings. EEG readings monitor electrical activity representing neuronal activity in specific neurophysiological regions. Rapid eye movement (REM) sleep is characterized by desynchronized, saw-toothed theta rhythm waves and heightened cognitive activity. Comparatively, high amplitude, synchronous delta waves, and sharp hippocampal waves characterize slow wave sleep (SWS) sleep (stages 3-4 of non-REM sleep) (Tucker et al. 2006).

While awake, beta waves are active in the brain. The first stage is known as REM. This is where rapid eye movement occurs. As well, dreams typically occur here. As you begin to fall asleep these beta waves become less prevalent and theta waves start to develop. This occurs in the early stages of sleep. Furthermore, this stage is known as N1 which is a light sleep that usually occurs for about five minutes. During this time body temperature drops and shallow, irregular breathing occurs. The next stage is known as N2. An EEG would show sleep spindles at this point. As time goes on the brain will begin to produce delta waves. These waves are long and slow. They occur in the deepest stages of sleep known as N3. This stage is also responsible for growth hormones being released in the pituitary gland. After N3 the body will begin to wake up on its own. The body will return to it's REM stage where body temperature increases and eyes have movement.

The brain at this point is filled with delta waves, more commonly know as slow-wave sleep. This is technically where sleep begins, “Scientists now have concrete evidence that two groups of cells—the ventrolateral preoptic nucleus in the hypothalamus and the parafacial zone in the brainstem—are involved in prompting SWS” (Scientific America). When these cells begin working, it triggers a total loss in consciousness. The beginnings of dreaming happen in this stage due to it being such deep, uninterrupted sleep. It is during this stage of sleep that sleepers can regularly experience night terrors, sleep-walking, sleep-talking, and bedwetting. If a sleeper awakens during this stage, they can take up to 30 minutes to return to normal mental conditions due to feeling extremely groggy. Stage three accounts for 15%-20% of total sleep time in a

There are many different stages of sleep. "The first stage is called Alpha. Alpha stage is the state of sleeping

The next stage in the Non-REM sleep is the N2(R&K Stage 2). At this point a person’s body temperature will start to decrease along with a slowing heart rate. Sleep spindles, which are quick movements of activity of the brain

This stage is believed to help people enter deeper stages of sleep (4). Stage 3 sleep consists of 20-50 percent delta activity and stage 4 sleep of more than 50 percents delta activity (4). Stages 3 and 4 are characterized as being slow wave sleep in addition to being the deepest levels of sleep. Approximately 90 minutes after being asleep, people enter rapid-eye-movement (REM) sleep (4). REM sleep consists of rapid eye movements, a desynchronized EEG, sensitivity to external stimulation, muscle paralysis and dreaming (4).

NREM (non-rapid eye movement) sleep occurs during first 90 minutes of sleep and is passing time through the four stages of the NREM cycle (Feldman, 2015). All the stages of NREM sleep each have specialized sleep-wave patterns occurring to what stage of sleep one is in. Lasting only a few short minutes, stage 1 sleep is the transition period between wakefulness and sleep (2015). Many college students create the golden “winding down effect”, eyes drooping and phasing in and out of “I was not sleeping; I just closed my eyes for a little” during stage 1. The level of difficulty to awaken from sleep increases exponentially when entering stage 2 of the NREM cycle. The brain waves in this stage develop slow, regular patterns with “…momentary interruptions

During sleep research, psychologists observed changes in people as they slept. Different eye movements were observed. During a certain stage of sleep a person’s eye suddenly began to move rapidly back and forth when people were awakened during rapid eye movement or REM they mentioned they were dreaming. Even though our eyes move during dream sleep our muscles become paralyzed during this stage. Which prevent us from moving other areas of our body such as legs, arms. Consciousness is different levels of awareness of one’s thoughts and feelings. We enter an altered state of consciousness every night when we go to sleep. Sleep consists of five different stages that involve different levels of awareness, consciousness and

In the past twenty-four hours, I have experienced each of these levels of consciousness and below I will describe what I met along the way. There are two major levels of sleep, N-REM (non-rapid eye movement) and REM (rapid eye movement). As mentioned before, there are five stages of consciousness that one goes through while sleeping, these stages are 1, 2, 3, 4, are N-REM (non-rapid eye movement) and REM (rapid eye movement). The different stages categorized by brain activity and behavior while awake and asleep. The only stages of these that I am aware of occurring to me are stage 1 of N-REM and REM. As I start to fall asleep, I enter stage 1 of the N-REM level of sleep. I am aware of this every night when I start to relax and doze off. Before bed, I usually lie down and play a game on my phone to help me relax. While I am in the middle of playing I will drift off to sleep. After falling asleep, I go through stages 2, 3, and 4 without being aware of

Brainwaves start to slow down. Stage 2: Eye movement stops and brain waves begin to become very slow. Stage 3 and 4: These are the stages where deep sleep begins. Also this is the most rejuvenating stage of sleep for the body. Stage 5: This stage is called R.E.M sleep, or rapid eye movement.

This stage is where we can be woken up the easiest. Stage 2 is where our brain activity and eye movement start to slow down and stop. Stage 3 brain waves start to begin with slow and fast movements. Stage 4 also known as deep sleep is the toughest stage to wake someone up. It is the stage where there is no eye movement or muscle activity and if you were to awaken during this stage. The results would be the feeling of grogginess

 There are five stages of sleep, REM and NREM stages 1, 2, 3, & 4.
