What Are The Four Stages Of Sleep, Stage 2?
There are four stages of sleep, stage 1 occurs when the person decides it’s time to fall asleep. Initially in stage 1 alpha waves start waxing and waning bursts of 8-12 Hz’s EEG. This is when we are alert at our wake fullness. Stage one sleep RRG is low voltage but high frequency signal. As the stages progress into stage 2 there’s a gradual increase in EEG voltage and decrease in EEG frequency. Stage 2 has a higher amplitude and lower frequency and also has two wave forms, k complexes and sleep spindles. Stage 3 is Delta waves, which are the largest and slowest EEG waves. Stage 4 is essentially the predominance of delta waves. Throughout the night the body goes through these 4 stages numerous times. It is a continuous cycle until the body fully

    Sleep Journal

    David Myers, the author of Exploring Psychology the eighth edition, says, “Everyone needs to get eight hours of sleep” (Myers, 75). This quote I think is so underrated, because some people in our world today only get six to nine hours of sleep, on a daily basis. If you think about it, going to sleep is not that easy. There are five unique stages to sleeping. In stage one, this cycle is considered to be between being awake and slightly dozing off. When you are in this cycle, you wake up, but you do not feel like you fell asleep. The brain produces theta waves, which makes the brain waves decrease when you go into other sleep stages. In stage two, the brain begins to relax more. The sleep spindles, which are rapid, rhythmic brain waves, are present in this cycle. Your body temperature starts to decrease and your heart rate starts to slow down. In stage three, this cycle is forwarded to deep sleep. In stage four, you are in a deep sleep, but not enough to dream. Also in this cycle, “some children might wet the bed or even sleep walk” according to David Myers. In stage five, also known as the rapid eye movement (REM), the heart rate increases and eyes begin to move under the eyelids. Most dreams occur here because the brain activity was increased.…

    Psy240 Checkpoint Sleeping and Dreaming

    There are four primary stages of sleep in which human beings cycle in and out of (Pinel, 2007). The first stage is referred to as emergent sleep. During this phase EEG waves are both low voltage and high frequency. The second, third, and fourth stages are made of higher levels of EEG voltage and a decrease in frequency. The second stage of sleep mainly process two additional characteristics which are sleep spindles and K complexes (Pinel, 2007). Delta wave patterns can happen during the third stage of sleep. As the fourth stage of sleep occurs the delta waves become the most dominant pattern within an EEG (Pinel, 2007).…

    Psy 240 Sleeping and Dreaming

    As we sleep we hit four different stages of sleep. The first stage is stage 1 EEG or initial stage 1 EEG which is described as a low-voltage, high-frequency signal that is similar to, but slower than that of alert wakefulness. During the progression from steps 1, 2,3 and 4 there is a slow increase in EEG voltage and a drop in the frequency of EEG. Stage 2 has a slight higher amplitude and a lower frequency compared to stage 1 EEG, it also has two wave forms K complexes and sleep spindles. K complexes is a large negative wave or upward deflection with an immediate large positive wave or downward deflection. Stage 3 EEG also known as Slow-wave sleep (SWS) has the occasional presence of delta waves which are the largest and slowest EEG waves. Stage 4 EEG which is also part of (SWS) has predominately delta waves, and you shall remain at stage 4 for some time.…

    As the sleeper goes into Stage 2 of sleep, their brain waves become even slower and a greater amplitude. These are called theta waves. This shows that the brain is becoming increasingly more relaxed. During this stage of sleep, it is common to experience sudden bursts of brain activity: known as K complexes and sleep spindles.…

    Nt1310 Unit 4 Lab Report

    The development of the electroencephalograph led to dramatic increases in what is known about sleep. When electrodes are attached to the face and scalp of sleepers, different patterns are produced on the graphic record called the electroencephalogram or EEG. The patterns vary in frequency and amplitude of the waves shown on the EEG. These waves reflect patterns of brain activity. It was discovered that the patterns on the EEG change throughout the night to correspond to various stages of sleep.…

    The Science Behind Sleep Walking

    Sleep is categorized into stages of a cycle between REM sleep and NREM sleep. NREM sleep is further divided into four stages: stage 1 (a light sleep period), stage 2 (a consolidated sleep period), and stage 3 and 4 (slow wave sleep periods). This is followed by stage 3, stage 2, stage 1, and a REM period. In normal adults, a cycle will last about 1.5 hours. The length and content of sleep cycles change throughout the night as well as with age. Sleepwalking generally occurs during the first third of the night (between 11 p.m. and 1 a.m.)During the slow wave NREM sleep stage. High delta activity within the brain usually accompanies slow wave NREM sleep, and when 20–50% of all activity is delta activity, stage 3 is scored. When delta activity reaches 50% or higher, stage 4 is scored. Usually, if sleepwalking occurs at all, it will only occur once in a night.…

    Sleeping Patterns In Othello

    There are four stages of Non-REM sleep. In the first stage, you can be awakened without difficulty but it may leave the person feeling as if he or she has not slept. In the second stage, the body temperature and heart rate drop. At this point, your body gets ready to enter deep sleep. The last two stages are deep sleep stages, with the fourth being more intense. These stages are known as slow-wave, or delta, sleep. If woken up, you may feel disoriented for a while. REM sleep is described as sleep where rapid eye movement occurs. It is also known as “active sleep.” It is during REM sleep that we being to dream. On average a person can have 3 to 5 periods of REM sleep per night. REM sleep is characterized by a number of other features including rapid, low-voltage brain waves, irregular breathing and heart rate, and involuntary muscle movement. Sleep provides the human body with the energy it needs to keep on going. During the state of sleep, the body’s metabolic processes slow down and energy consumption is kept to a minimum. The human body requires rest to sustain its everyday activities, and hence sleep is…

    Regulatory Behavior Paper

    The nervous system is an extremely elaborate biological machine. Without question, the nervous system is a system so intricate and comprehensive that professionals in the field of medicine to this day do not have a “complete picture” of each of the working details of the human nervous system. Of these different mechanisms, perhaps the one most riddled with speculation, is the mechanism of sleep. In discussing regulatory process, sleep is perhaps one of the most essential to the healthy upkeep of the human nervous system. This process is such a necessary behavior that without it, the nervous system, and the overall health of the individual in question can become compromised (to the point of fatality) without it.…

    Brain Waves In Germany Around The 1920's

    In Germany around the 1920’s, a psychiatrist by the name Hans Berger, Created a tool that would help researchers study and measure the rhythmic electrical activity in the brain. This tool would pick up the brain waves and create an EEG or electroencephalogram. This device has played an important role in the studying of our sleeping patterns. There are two different brain waves that occur when entering sleep. There is the beta brain waves that generate fast while preparing for you slumber and then as soon as you lay down your brain activity, along with motor skill and physical activity begins to decrease and relax.…

    Biological rhythms and aggression notes (PSYA3)

    The stages of sleep are an example of an ultradian rhythm, repeating roughly every 90 minutes while asleep. Since the invention of the EEG in the 1930’s the research into stages of sleep has drastically increased. In 1968, Kales and Rechtschaffen discovered four distinct stages people entered during sleep. Stage 1 usually lasts for roughly 15 minutes at the beginning of the cycle and is characterised by slower ‘theta’ brain waves. Stage 2, lasting about 20 minutes is characterised by sleep spindles (bursts of high cognitive activity) and K-complexes. Following this is stage 3, which lasts for 15 minutes. In this stage, brain waves slow and increase in amplitude and wavelength, developing into delta waves. Stage 4 is similar to stage 3 and is when a person is most relaxed and most difficult to wake. The fifth stage of sleep is called REM (as opposed to stage 1-4 which are NREM stages). During REM sleep the brain is almost as active as it is during the day. Sleep paralysis also…

    Stage #4: brain produces Delta waves stage three and four are called deep sleep cycle. It is important to go through adequate sleep and get the sleep cycle run its course correctly. Our body repairs itself during sleep. Our body has an ingenious way of restoring our body as we sleep; during the day, there is a buildup of different chemicals including adenosine. All of these chemicals are what is thought to make us want to sleep. Scientists have discovered an immunity system in the brain that is called the lymphatic system. The glymphatic system is the main system that clears the waste product that build up in your brain.…

    Chapter 4: States Of Consciousness

    The suprachiasmatic nucleus (SCN), is an input from the retina to synchronize rhythm with the daily cycle of light and dark. The desynchronization of the biological clock can affect sleep patterns. It can lead to sleepwalking or insomnia which can lead to sleep deprivation. There are two stages of wakefulness and five stages of sleep. The stages if wakefulness is beta, which reflects concentration and awareness, it's in the highest frequency and lowest amplitude. Alpha waves are associated with drowsiness and relaxation. The first stage of sleep is light sleep, which is characterized by drowsy sleep, where an individual experiences myoclonic jerks, the second stage is deeper sleep, where muscle activity decreases. Stages 3 and 4 are characterized by delta waves, deepest sleep, in which bedwetting, sleepwalking and talking occur. REM sleep is an active stage of sleep, which dreaming occurs. "Stages 1-4 is referred to as non-REM sleep, which is characterized by the lack of rapid eye movement and little dreaming. One sleep cycle lasts 90-100 minutes. Chapter 4 also went oversleep…

    REM Sleep

    Contrary, to these ideas the brain is in a state of activity to the same extent of consciousness. During this stage, dreaming as well as REM sleep result in an increase of heart rate rise of blood pressure, and faster and more irregular breathing habits. These periods last from a few minutes to as long as an hour, averaging in twenty minutes in length. The cycle is repeated throughout the night about every ninety minutes. Whenever they begin the pattern of activity from the sleepers brain changes to resemble that of alertful…

    Personal Narrative: The Five Stages Of Sleep

    After stage 1 and two then follows stage 3, during stage delta waves appear 20 to 50 percent of the time, and in stage 4, they appear more than half of the time. This a crucial stage of sleep because If I want to be fully rested for the morning, I need to experience these deeper stages of sleep throughout the night, but having my roommate coming home late it can easily ruin that for me and disrupt my sleep. In the final stage of sleep, stage 5 or also known as REM sleep. Stage 5 is different from the other four stages because in this stage we go through rapid eye movement while in the other four stages it is none rapid eye movement. During this stage I will get an increased heart rate and blood pressure, as well as rapid irregular breathing, a state that occupies about 20 to 25 percent of our night's sleep. After 10 to 20 minutes of REM sleep, the…
