The Different Stages Of Light Sleep
Stage 1 “light sleep”. In this stage of light sleep, which lasts about 5 to 10 minutes our brains activity powers down by 50 percent or more, producing theta waves. Theta waves occur four to seven times per second. Moreover, these waves are slower than the beta waves of 13 or more times per second produced during active alert states and the alpha waves of 8 to 12 times per second when we’re quiet and relaxed. As we start to drift off to deeper sleep, we become more relaxed, and we may experience hypnagogic imagery (scrambled, bizarre, and dreamlike images that flit in and out of consciousness).

Stage 2. In stage two, our brain waves slow down even more. Sudden intense bursts of electrical activity called sleep spindles of about 12 to 14 cycles

    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.…

    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.…

    Stage 2 sleep evolves into Delta sleep or slow wave sleep in approximately 10-20 minutes and may last 15-30 minutes. It is called slow wave sleep because brain activity slows down dramatically from the theta rhythm of stage 2 to a much slower rhythm of 1 to 2 cycles per second called delta and the height or amplitude of…

    Activation Synthesis Theory

    There are four stages of sleep: Stage one shows low-voltage, high-frequency signals on an EEG similar to those produced while awake, though slightly relaxed. There is slow voltage increase with an immediate drop in frequency through development in stages. Stage two is marked by two diverse wave formations called a K complex and a sleep spindle. Stage three is interrupted by an intermittence of delta waves which are great and measured, while stage four is predominantly delta waves. (Pinel, 2007) After a period of interval in stage four, the sleeper returns to an altered stage one; stage one is reformed from the initial stage because subsequent repeats of stage one are obvious by a loss of muscle tone, REM (rapid eye movement), dreams, and an…

    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…

    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.…

    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.…
