(I was allowed permission by you to turn in this term paper due to some personal issues with the original term topic)

Ever wondered what in blue blazes your brain is doing when you sleep? Well so far, all the research and experiments that have been made to understand and answer this question have resulted with the so called six stages of sleep. The six stages of sleep starts from Stage 0 to Stage 5. Stage 0 is not really considered a stage since it involves the person of interest being awake. Sequentially, Stage 1 is considered to be the beginning of being asleep. Following Stage 1 is Stage 2 which is well known for its sleep spindles and K-complexes (L & F 8). Afterwards, Stage 3 is considered to be a transition phase towards Stage 4 and both stages are collectively often titled as deep sleep (McPhee 20). Lastly, but not the least, Stage 5 is identified as dream sleep and with REM (McPhee). Each stage is not just discerned by its major aspects, but by the activity in the brain in each stage. Although sleep can be described through the various behavioral changes, the different activities in the brain allow the discerning of each stage during sleep. Each stage is distinguished by various electrical activities and patterns across the brain (L & F 7). These electrical activities and patterns consistently change between each stage (McPhee 17). Obviously, each stage has its own unique electrical pattern, and these patterns can be recorded by a machine called the electroencephalograph. This device can detect any electrical change made by the activity of nerve cells in the brain and record it on an electroencephalogram, also known as EEG (McPhee 18). Along with the classifications of sleep stages through the different EEG patterns, two diverse types of sleep…...

...Sleep deprivation is defined as a sufficient lack of restorative sleep over a cumulative period so as to cause physical or psychiatric symptoms and affect routine performances of tasks. (WebMd) Sleep deprivation can lead to harsh physical and or mental problems and should be taken seriously. We are now living in a 24/7 world where we are constantly busy and there is work, television and electronics keeping us up. Getting the proper amount of sleep should be taken very seriously so that there are no harmful effects to your body or mind. Sleep is something that you cannot live without, just like the food we need to eat or the oxygen we need to breathe. Sleep may be the last thing we feel there is time for but it should be made a top priority. There are several consequences, such as accidents or disasters, that are a result of sleep deprivation or lack of sleep and everyone should make a conscious effort to improving the way they sleep. Sleep debt is a major factor in accidents and can cause slow or delayed reactions times. Slowed reaction time can be dangerous while driving a vehicle or even operating machinery. Not only could you harm yourself due to a lack of sleep but others could be in harms way as well. An example of sleep deprivation and slowed reaction time would be the Exxon Valdez disaster. This accident was a major disaster in where oil was spilled all over and harmed many living creatures. In “Sleep Debt and the Mortgaged Mind” William C. Dement and......

4 Stages of Sleep

...You have four stages: 1- Theta waves (high amplitude, slow waves) for 5-10 minutes, transition between awake and asleep 2- Sleep spindles for 20 minutes, body temp goes down and heart slows 3- Delta waves emerge (deep slow brain waves) this is the transition between light and heavy sleep 4- "Delta sleep", you're definitely having delta waves, you're in deep sleep and might sleepwalk, bed wet etc...30 minutes - REM...Rapid eye movement, increased breathing, and increased brain you'll dream you cycle through these five stages 4-5 times a night like this 1, 2, 3, 4, 3, 2 THEN REM (where you dream etc.), then back up and down. Common problems include sleep apnea (usually overweight males), sleepwalking, bedwetting, insomnia, chronic fatigue, restless leg syndrome, and narcolepsy Narcolepsy- daytime uncontrollable sleepiness, may fall asleep...caused by dysfunction of the brain mechanism that controls sleeping and waking Sleep apnea- disorder in which you’re breathing temporarily stops throughout the night. Can be caused by being overweight or any kind of blockage of the upper airways Sleepwalking - complex behavior accomplished while asleep, you can talk, even have your eyes open. Have a lot of causes like genetic predisposition or environmental causes like sleep deprivation or stress. Rapid eye movement is the stage in which we dream every night. There are 5 stages of sleep. The first stage is a transition phase called Alpha Theta, eyes roll slightly, only lasts...

...A Good Night’s Sleep- What is sleep? Sleep is defined as unconsciousness while are brain is still active processing and rejuvenating period. Sleep is a physical and mental resting period in which a person is unaware of their environment. In a normal sleep our body is changing by decreasing body temperature, blood pressure and other body functions. Sleep is very important to us and everyone for that matter because we all need to sleep and rest our bodies. It’s so important because it’s a vital biological function without sleep we know that our bodies are unable to function the way we want them to. We lose lack of day-time alertness, drowsiness and more susceptible to health problems such as stroke, diabetes, obesity and even depression. In the article ("Good night’s sleep") they discuss about College students sleeping patterns changing for example, not getting enough sleep. I felt that the article didn’t have information about sleeping patterns when there has been research about sleeping patterns. In 2002 Canadian Community health survey found that 18% of people sleep 5 hours or less a day. Sleep is put into two parts one being called non-REM and REM (Rapid Eye Movement). Non-REM consists of four stages of sleep, each deeper than the last. REM is when you are at the most active sleeping you are dreaming and your eyes are moving rapidly. Our sleep patterns consist of stages 1-4. Stage one last about 5 minutes, easily awaken. Stage 2 first stage of sleep about first 25......

...definition of terms. Background of the Study Sleep is an integrated part of human health and life and is crucial for learning, performance, and physical and mental health. Sleep deprivation is a serious problem facing individuals in many critical societal roles. It is the condition of not having enough sleep; it can be either chronic or acute. A chronic sleep restricted state can cause fatigue, daytime sleepiness, clumsiness and weight loss or weight gain. It adversely affects the brain and cognitive function. Few studies have compared the effects of acute total sleep deprivation and chronic partial sleep restriction. Complete absence of sleep over long periods is impossible for humans to achieve (unless they suffer from fatal familial insomnia); brief micro sleeps cannot be avoided. A National Sleep Foundation survey found that college/university-aged students get an average of 6.7 hours of sleep each night. Sleep deprivation is common in first year college students as they adjust to the stress and social activities of college life. A study performed by the Department of Psychology at the National Chung Cheng University in Taiwan concluded that freshmen received the shortest amount of sleep during the week. In 1997 the University of Minnesota did research that compared students who went to school at 7:15 am and those who went to school at 8:40 am. They found that students who went to school at 8:40 got higher grades and more sleep on weekday nights. One in four U.S.......

...Sleep deprivation in college students is very common with consequences that affect their physical and mental health. Peer pressure from friends or roommates and the demands of school and jobs leave many teens and college students chronically sleep deprived. Many college kids don't think they need the required hours of sleep necessary for good physical and mental health. In error many think that their youthful energy is enough to keep them going rather than a good 8 hours of sleep. What is sleep deprivation? The best definition of sleep deprivation is found by WebMD. "a sufficient lack of restorative sleep over a cumulative period so as to cause physical or psychiatric symptoms and affect routine performances of tasks." Sleep deprivation is a lack of sleep or not getting enough sleep, unlike insomnia which means a person has trouble falling and staying asleep. Much of society suffers to some extent from sleep deprivation. But ignoring the advice to "get plenty of sleep" has an exaggerated impact on the bodies and minds of college students. Faced with the famous dilemma: "Study, friends, sleep -- pick two," it is often "sleep" that students delete. Sleep deprivation, especially during exam periods, is a way of life for students. A recent study by the National Sleep Foundation (National Sleep Foundation, 2009) )found that “63% of college students do not get enough sleep.” Fifteen percent of college students admitted that they fall asleep in class. Those students who......

...English Importance of sleep. Sleep is very important and beneficial part of our lives. Sleep helps us to have a better quality of life, but nowadays not sleeping well has become part of the lives of many people. The sleep needed is between 7 to 9 hours, but some people get 6 hours or less. Sleep deficiency can be presented at any time of our lives, as adult people, teenagers and even in children. Sleeping well helps us physically and mentally. It is known that sleep plays an important role and helps us to improve our memory, health, learning and metabolism. Also sleep has an big impact on our life and it can bring a lot of consequences such as, long term diseases, car accidents, memory problems, shorter life, lower grades, deficiency at work, mad mood, poor performance exercise and extra activities. One of the consequences that lack of sleep brings is long term diseases. If we do not sleep what we need, we can increase the risk of developing cardiovascular disease and hypertension, metabolic problems such as, obesity and diabetes and emotional disorders such as, depression and bipolar disorder. When we deprive our bodies of sleep, it raises ghrelin which it is a hormone that regulates the need to eat. When we do not sleep, that hormone increases causing us want to eat more when we do not need it, so that is when obesity problems are presented. Also, sleeping decreases leptin which is another hormone that regulates the need to eat and when it decreases, we will have the......

...occurs. Sleep is truly a wondrous process. During sleep, our brain takes our bodies through five different stages: rapid eye movement and non-rapid eye movement, otherwise known as NREM, which represent four of the five stages. Each stage corresponds differently in length and produces different brain waves as well as dreams. The first stage of sleep is very brief and the sleeper experiences hypnogogic sensations. Stage two is a deep, twenty-minute cycle, and the third is short in length, much like the first. However, it is also the transitional period into stage four, which lasts thirty minutes long. REM sleep ends the course of the sleep cycle, lasting a total of ten minutes or more. Sleep begins in stage one and progresses into stages two, three, and four. After stage four, stage three and then stage two are repeated before entering REM sleep. The total time it takes for a person’s body to go through all five stages is about 90 minutes. Stage one is a very light sleep. The person is not technically asleep yet, for he/she is easily awakened. During this stage, many people may experience hallucinations that are mistaken for dreams and/or falling/floating sensations. David Meyers defines hallucinations as, “[f]alse sensory experiences, such as seeing something in the absence of an external visual stimulus.” (p.94) Many people will recall being pinned to their bed or floating, when in reality it was the normal occurrences of the first stage of sleep. During this......

Sleep Stages

...Stage 1 This is the beginning of the sleep cycle and is a relatively light stage. This is more of a transition period between wakefulness and sleep. In Stage 1, the brain produces high amplitude theta waves, which are very slow brain waves. This period of sleep lasts only a brief time (around 5-10 minutes). Stage 2 This stage lasts for approximately 20 minutes. The brain will begin to produce bursts of rapid, rhythmic brain wave activity known as sleep spindles. Your body temperature starts to decrease and heart rate begins to slow. Stage 3 This is deep, slow brain waves known as delta waves begin to emerge during stage 3 sleep. Stage 3 is a transitional period between light sleep and a very deep sleep. Stage 4 At this stage, sometimes referred to as delta sleep because of the slow brain waves. This is a deep sleep that last for approximately 30 mins. Dreaming A majority of the dreaming occurs during the stage referred to as REM, or the rapid eye movement stage. This is characterized by eye movement, in which the eyes dart back and forth under the eye lids. Dreaming occurs during this stage because of increased brain activity, voluntary muscles become paralyzed. There are five common beliefs about dreaming. They are: External stimuli are incorporated in to our dreams. Dreams last only an instant. They do not dream. Penile erections indicate sexual content of dreams. Sleep talking/walking can occur. Two common theories that have been......

...the journal Sleep, snoring is associated with a higher risk of carotid atherosclerosis, which is the accumulation of plaque in arteries that supply blood to the brain. The researchers brought in 110 participants, including people who snored and others who didn't. The participants underwent a sleep study, in which their snoring and breathing patterns were measured while they slept. They also underwent ultrasound assessment of their carotid arteries to measure atherosclerosis. People who snored more often were much more likely to have carotid atherosclerosis, but curiously, not atherosclerosis in the arteries in their legs. One of the possible connections between snoring and this health risk is the vibration of the snoring. All that rattling in your throat may vibrate your carotid arteries, particularly a specific spot where plaque often forms. Researchers know that this vibration damages cells in artery walls, which could trigger the early formation of atherosclerosis. This buildup of plaque can then set the stage for a stroke if a blood clot forms on the plaque blocking the artery, or if a piece of plaque breaks loose and becomes wedged in a smaller artery in your brain. According to the National Institutes of Health, more than half of all strokes in the United States are caused by plaque buildup in the carotid arteries, also known as carotid artery disease. Methods for reducing snoring, as recommended by the National Sleep Foundation,...

...Sleep and brain development: With the relevantly recent discovery of rapid eye movement (REM) sleep, the once subjective state of sleep is no longer expressed as a homogeneous occurrence of passive rest for the brain. Instead, REM sleep has, "appeared as an active condition of intense cerebral activity." (1). And to be even more interesting, the fact that as humans we get more sleep at younger ages, 25 and younger, when intense neurological development is taking place means that, "sleep may play a role in brain maturation." (1). A recent study has research sleep in young children as well as young adults. It has found that, "Sleep and sleep cycles begin at around 26 to 28 weeks' gestational age."(2) This means that patterns of REM and NREM have been found in infants, suggesting that there is some type of development taking place while in a sleeping state. The study goes on to show that, "Sleep and sleep cycles are essential for the development of the neurosensory and motor systems in the fetus and neonate. They are essential for the creation of memory and long-term memory circuits, and they are essential for the maintenance of brain plasticity over the lifetime of the individual." (2) Suggesting that sleep is essential for positive brain development for the rest of the life of that infant or young adults. It was also noted that any interference with sleep or sleep cycles can significantly hinder the early processes of sensory development. (2). It is clear that sleep is......

...1 Sleep Deprivation, Disorders, and Drugs Amanda Powell Psychology 240 3/14/14 Jennifer Graves 2 There is one distinctive time that I remember not having enough sleep and feeling deprived of it. I was up all night with my new puppy, this was just recent actually. She was sick all night, and I had to get up and go to a job interview in the morning, only being able to sleep for about 3 hours when I woke up I felt, as they say “groggy”, I was more tired when waking up than I had been going to sleep if that make sense. As the day went by I could feel the change in my mood, because I would snap very easy at things that were not pleasant. I felt emotionally drained and I was not my normal self, or how I would usually feel if I had gotten enough sleep the night before. My behavior felt as if I was trying to rush through things just to be able to get it done, because I had not had the motivation to do it, being so tired. Luckily when I went to the interview it was short, because they most likely could have told that I was sleepy. In the end I got the job, but I had felt very unmotivated and snappy all day. I think that sleep is important for one’s energy the next day. In my experience I believe that it is related to the effects that our book describes. I felt not myself in any sort, and I felt sleepier. That night I had fallen asleep very vast just as the text has described when a person is deprived of sleep. As well it may be just as described in the text that I was......

...Sleep Paralysis Symone Clayton English Composition 1 Abstract I was a sophomore in High School in New Haven , Michigan when In school I decided to walk home and skip school, my house was empty at the time so I decided to go into my room and take a nap and that’s when it happened for the very first time. I had awakened and I felt this heavy weight on my body and another feeling that I can only describe as if someone is lying on top of me, forcing me down (hence holding my whole body down) holding my lips and eyelids shut. I could hear though. This lasted for about 10 seconds. During these 10 seconds all sorts of thoughts started running through my mind questioning the reality of this phenomenon and even extended to states where I thought I must be dead! Then all of a sudden, my eyelids opened and I could look around I could even see from my peripheral vision that my brother was sleeping. I shouted and shouted but in vain. Within the next minute I had fully awakened and all of a sudden jerked up into a seated position on the bed. This was one of the most horrific and frightening experiences I have ever had. At that time, I didn’t even know what to call this episode I had experienced. I felt quite embarrassed to talk about it in general for a reason I don’t know till today. About six months later I started to do my own researches on the incident which had happened to me. My mother wanted me to start reading the bible more and go see Pastor and they felt it was a......

...Sleep 2015 Gabe Wai Sleep  is something that we can always have enough of, for our body to function fine with plenty of energy because our muscle repair, memory consolidation and release of hormones regulating growth and appetite have completed their phase in the body. 117 When you start drifting off your heart rate and breathing slows down. 1 Most children 6- 13 need to sleep from nine to eleven hours each night. a baby needs to obtain around 16 hours of sleep a day but it can be spread out over the course of one day.1 In a day a newborn will sleep throughout the day and will not sleep all the way through the night till about 1 year old because they don't need as much of feeding and are doing more in the day. 1 As people reach 14, they start needing less and less sleep until they are older than 65. 1 Most 26 - 64 need seven or nine hours of sleep. 1               When studying sleep doctors use several different machines but one way is using the EEG, which stands for Electroencephalography and measures Brainwaves on a graph. We have 5 different waves our body goes through at night.20 We have alpha/beta, theta, delta, and REM. 25Alpha and Beta are high frequency and low amplitude.25 Theta is high amplitude and low frequency.25 Delta is high frequency and very low amplitude.25 REM is high frequency and low amplitude.25 The way scientists know our body is sleeping is, they use a machine that uses the body's’ electrical waves given by the brain using polysomnography(......

Stages of Sleep

...There are five stages of sleep. They are 1. Falling asleep and trying to get comfortable. Some people can get through this stage in a few minutes and other people it takes longer. 2. You go into a light sleep. You can still be taken up easily here but you are starting to lose consciousness. Your heart rate and breathing slow down here. 3. You are in a deeper sleep and on to the 4th stage of deep sleep. This is also called delta sleep because of the delta waves of the brain. This is when your body relaxes and regenerates. The final stage is REM or rapid eye movement. In this stage you dream. There are some beliefs about dreaming which are: External stimuli such as a phone ringing or knocking on the door can intergrade into your dreams. Another belief is that dreams last a short time. Some also feel that they do not dream at all while others believe that erections are due to a sexual dream when they are actually due to sheets or something rubbing against the penis. Sleep walking and talking are a belief that happen while you dream. A couple of theories of dreaming are recuperation where your body restores itself and psychoanalytic dreams where your subconscious acting out your hidden desires or thoughts accord to Sigmund Freud. There are other theories about dreaming as well such as we dream as therapy to make sense of things. I think we dream for all of the reasons. I think that for me anyway, it helps me deal with things and realize things to make sense......
