The Biological Basis of Sleep

Introduction Sleep is a mental and physical state in which one becomes inactive and unconscious of the environment around him or her (Borbà ©ly, 2003). In the real sense sleep is just a partial disconnection from the world in which outside stimuli are obstructed from the senses. Normal sleep is indentified by a general reduction in most of the body functions including blood pressure, temperature, and the breathing rate. This is contrast to the human brain that never reduces in activity.Advertising We will write a custom essay sample on The Biological Basis of Sleep specifically for you for only $16.05 $11/page Learn More The brain is always active whenever a person is a wake or a sleep (Berger, 2007). A normal human being sleeps for eight hours. These eight hours are divided into two equal parts. The first part is the rapid eye movement, and the second is the non-rapid eye movement. The two parts form a cycle (Ishimori, 2004). The intention of this pape r is to look at the basis of sleep in relation to the biological mechanisms that cause people to sleep and stay awake. History of Sleep The history of sleep is believed to have been introduced by a psychologist professor at the University of Nagoya in Japan about one hundred years ago (Bayliss, 2006). The psychologist proposed a theory that explains the concept of sleep regulation. Kuniomi Ishimori and Heni Pieron neuroscientist state that, a hormonal chemical and not the neural network (Ishimori, 2004) cause sleep regulation. In earlier researches, researchers took some samples that were sterilized and dialyzed from dogs that had sleep then injected to the brains of the dogs that had no sleep. The dogs that received these samples fell after a short time. The scientists went ahead and took samples from normal dogs that did not have any sleep then introduced into the brains of other normal dogs without any sleep (Berger, 2007). The response showed that the recipient dogs did not slee p. This research indicated that there are substances that cause sleep known as â€Å"endogenous sleep-promoting substances.† Although the contradiction fact is that the nature of the chemical substances that caused sleep was not identified. Various research groups carried out their research and reported more than thirty endogenous sleep causing substances. In most cases, their physiological relevance was uncertain. Tokyo igakkai Zasshi from Japan published the first Ishimori’s paper entitled â€Å"true cause of sleep _ a hypogenic substance as evidenced in the brain of sleep deprived animals,† in the year 1909. Ishimori made further suggestion that when a person continuously stays a wake, it may also cause accumulation of factors that cause sleep in the brain (Borbà ©ly, 2003). Currently this is referred to as homeostatic sleep regulation. Starling and Bayliss discovered â€Å"scretin† in 1902. This is in relation with the existence of blood-borne messen gers. The new idea of hormonal control of the body functioning became quite fashionable and popular in those days.Advertising Looking for essay on biology? Let's see if we can help you! Get your first paper with 15% OFF Learn More Hans Berger a Germany neurologist in Jena invented an electroencephalogram (EEG) that records brain waves in 1920s. The discovery facilitated the qualitative and quantitative analysis of sleep. Until then, sleep was regarded as an unapproachable phenomenon mainly because it could not be explained scientifically. Kleitman and his coworkers discovered rapid eye movement (REM) sleep in Chicago. This discovery took place in the year 1953 in human beings (Bayliss, 2006). Jouvet and his group in Lyon identified that sleep is never a uniform phenomenon, and it consists of two main different stages. Sleep and wakefulness are the major complex, phenomena. Furthermore, sleep is divided into two parts: the REM and the non-REM sleep can easily be determi ned by examining the animal’s behavior (Berger, 2007). The authors suggest that it needs more accurate measurement of sleep and wake pattern by the use of the electrooculogram (EOG), the recording of the movement of the eye, EEG and (EMG) electromyogram, the recording of the tension of the muscles (Ishimori, 2004). When a normal, healthy person goes to sleep at eleven, the first step in sleeping starts with the NREM and then followed by the REM sleep. This makes a cycle in the sleeping pattern. As in the example, it all begins with the NREM that which progressively becomes deeper. It takes around four to five cycles in which one take about 90 minutes; arousal comes after the concluding REM sleep (Borbà ©ly, 2003). This principle has been in existence for a long time and yet the physiological regulatory mechanisms and the meaning have completely remained a mystery. Alexander Borbely from the Zurich University in Switzerland came up with his two famous process model that show sleep regulation in 1982. He argues that homeostatic process is entirely controlled by sleep pressure or sleep propensity that build up during the wakefulness period. The process is related to the Ishimori’s thus the name Ishimori-Pieron type. On the other hand, a biological or pacemaker clock that is independent of the prior waking and sleep determines the circadian process well known as the sleep-wake sequence during the night and day. This clock is found in the body of the animals. Researches indicate that Ultradian process can generate alternation of REM and NREM sleep (Pià ©on, 2003). From a scientific point of view, the molecular mechanisms that explain the sleep- wake regulation in all the processes have remained unknown.Advertising We will write a custom essay sample on The Biological Basis of Sleep specifically for you for only $16.05 $11/page Learn More Sleep and Prostaglandin Prostaglandins (PGs) are the lipid mediators (Bayliss, 2006 ). There are more than thirty kinds of prostanoids, which are known worldwide. The compounds are distributed extensively in all mammalian organs and tissues. They have a diverse and numerous biological effects on various pathological and physiological activities in the body, and that is why they are sometimes called local or tissue hormones. In 1980s, the scientists discovered the most common prostanoid in the mammalians and mostly the rats and human beings (Berger, 2007). According to their findings, they suggest that PGD2 can be a distinctive component of the brain and might be having some essential function in the organ. They found out that when PGD2 cause sleep to rats when it is microinjected in the brains (Pià ©on, 2003). This was a notable achievement, and they decided to carry on with the study to the molecular mechanism and the physiological significance. Inoue and Honda from Tokyo Japan first designed the bioassay analysis system for sleep. The analysis of the structure i s as follows: through microinjection pump, the chemical PGD2 is injected gradually and constantly through a cannula which is chronically rooted in the 3rd ventricle of a rat . The stages that the rat undergoes to sleep are determined using polygraphic recording of EMG and EEG. Other aspects like food intake, water intake and brain temperature, are monitored and the general behavior of the rat is recorded using a video recorder under infra-red light. The rats are nocturnal animals that sleep most of the daytime, and remain active during the night. The outcome of the research showed that when the PGD was constantly injected in the third ventricle of a rat, the REM and the NREM sleep improved significantly during injection time. PGD2 caused the effect since the other PGs were ineffective (Borbà ©ly, 2003). The experiment mostly depended on the dose and the little picomolar quantity of PGD2 given to per minute it was enough to cause excess sleep to the rat. The quantity of the PGD2 tha t required causing sleep corresponded quite closely to the normal concentration inside the brain (Pià ©on, 2003). The results indicated that pharmacologically high doses are not necessary, and it can imply that the difference in the concentrations of PGDs which ordinarily occur in the brain have the ability to control sleep under physiological circumstances (Berger, 2007).Advertising Looking for essay on biology? Let's see if we can help you! Get your first paper with 15% OFF Learn More The most important aspect is that the PGD2 stimulated sleep was the same as the physiological sleep just as shown by electrophysiological principle and conduct that involves power spectral data. Contrary to PGE2, the PGD2 is never pyrogenic, but in the real sense, it caused little amounts of reduction in temperature as seen to happen throughout the physiological sleep (Ishimori, 2004). Others experiments, that were carried out, in Japan with monkeys, Mocaca mulatta, indicated clearly that PGD2 could induce natural or physiological sleep (Bayliss, 2006). The sleeping pills and drugs cause quite different sleep from the physiological sleep or the natural one. This shows that PGD2 is a true sleep hormone. Sleep-wake regulation The discoveries in the experiments above explain how sleep can be introduced to an animal from the beginning until it gets into a deep sleep. Then the next part is to identify if the same experiment can apply in the process of waking up the animal from the sleep explaining the wake sleep process. Philos published the brief summary of the experiment in the year 2000. The article observes that the main enzyme that induces sleep is mainly found in the arachnoid membrane and the choroid plexus. After this enzyme is generated, PGD2 is secreted into cerebrospinal fluid (CSF) and then flows inside the subarachnoid and ventricular spaces. The PDG receptors known as the DPRs are localized on the little area on the ventro-rostral plan of the basal forebrain. PGD2 that circulates in the CFS binds the receptors at the point where the sleep signal is generated (Pià ©on, 2003). The signal passes through the parenchyma brain to the ventrolateral preoptic area VLPO), which is a centre for sleep, across the pia membrane (Ishimori, 2004). The process is mediated through adenosine by A2A adenosine receptor. VPLO cast to the tuberomammilary centre (TMN) (Berger, 2007). The scientists, Oishi and coworkers, found out that adenosine from the TMN cause sleep by h indering the histamnergic structure via A1 receptor (Bayliss, 2006). This implies that PGD2 induce sleep by facilitating the functioning of sleep neurons (Borbà ©ly, 2003). On the same point, wake materials like orexin or PGE2 thruogh the histamine mechanism support an organisms’ wakefulness. According to the scientists, it is their view that the work on wakefulness still requires great attention and it forms the basis of greater basis for more investigation. Stages of sleep Sleep has four main stages. It starts from dozing and continuously progresses into a unusually deep sleep. Stage one The stage is can be termed as a doing stage. In this stage, five percent of the non-REM is spent. It is the transitional phase of the exact light sleep. The birthing rate, and the muscles start to relax and a person can be easily awakened (Berger, 2007). A person may feel a hypnic jerk during this period, the tendency to fall asleep and come back easily. After the rush of activities, the b ody starts to get into a slight slumber. The EEG at this stage is low, and the eye movements are slow. The eyes roll slowly as though closing and opening. Stage two This is the official onset of a consolidated sleep. A bout forty-five percent of the non-REM sleep is covered in this step (Pià ©on, 2003). The eye movement stops then the brain waves enlarge. There are two distinct brain waves in this stage, K-complexes and spindles (Borbà ©ly, 2003). A sleep spindle is a design by which EEG waves that consist of a burst of eleven to fifteen hertz wave that last from five to fifteen seconds. A K complex has quite a high voltage of EEG activity. It consists of a sharp downward constituent then followed by a slow upward constituent. This pattern lasts for over five seconds. Stage three As the sleep advances deeper and deeper, it becomes extremely difficult to arouse someone at this stage. An individual may spend about twelve percent of the non-REM sleep in stage three. Real slow wave sl eep starts with slow and large wave in amalgamate little, faster ones. Stage four This stage is normally characterized by extremely deep sleep. It mostly spends round seventy-five percent non-REM sleep, and thirteen percent of this part is spent in the last stage (Berger, 2007). An individual in the last two stages is more difficult to wake than an individual who is in the first two stages (Bayliss, 2006). People who wake up from sleep normally feel disoriented and groggy for some time. REM sleep This is the period that a person may experience dreams. During this time, there is an irregular breathing, periodic eye flattering, there is also an irregular heart rate, blood pressure and body temperature. This makes a difference between non-REM and REM sleep stages (Ishimori, 2004). In other words, the REM is referred to as paradoxical sleep since brain wave activities is almost similar to a wakened state. During this stage, the brain obstructs all signals towards the muscles and they re main immobile so that the dreams cannot be acted out (Pià ©on, 2003). Most adults spend a round twenty to twenty-five percent of their sleep in REM. Conclusion The biological basis of sleep is dated back to more than one hundred years ago. Kuniomi Ishimori and Heni Pieron laid the foundation of sleep through their research done in Japan. The later physiologists identified that sleep can be classified into two main groups. These are the REM and the non-REM (Bayliss, 2006). All the two parts come in different stages, that is beginning from stage one up to stage four, all the stages follow one another from the beginning of sleep to the time a person wakes up. There is still more room for other scientists to make the research and prove the sleep phenomenon.

The third stage, norming, the group members have overcome conflicts and have begun to establish group norms, where roles, standards and responsibilities are defined and carried out. Finally, performing stage, as the term implies, focus on performance of tasks where roles become functional and flexible as deemed appropriate. The five soft skills employers look for in today’s workplace are: proactive attitude, problem-solving, the ability to manifest a vocation of service, teamwork, and exemplary communication skills (Tarnogol, 2010). In the academe, one has experienced working with going through the phases of team development through group work where course modules would require a project to be accomplished as a group. The most eminent phase of team development that the group centered on was the performing stage, where all members have recognized the need to comply with the defined roles and responsibilities to enable the accomplishment of group goals. For example, in English class where the group was expected to create a presentation about literary elements of a novel, all the members prepared to work on the tasks assigned. Apparently, one could attest that the three prior stages were briefly experienced (forming, storming and norming), particularly the need to define goals, roles and responsibilities under the forming stage and the experience of conflicts under the storming stage. The performing stage, however, was most memorable in terms of defining the ability of members to collaborate and actively participa te to ensure that the defined objectives and tasks are effectively carried out.

Kierkegaard and Dewey Essay Example | Topics and Well Written Essays - 1500 words - 1

Kierkegaard and Dewey - Essay Example Dewey then gives an example of religion; how religion can have a lasting and deep impact on the course of a nations history. Religion or a certain set of ideas can control peoples feelings and beliefs, and that is not any less of a control than that of political oppression. Culture is also determines what elements of human nature dominate it, which have resulted in the belief that one aspect of human nature is the determining factor of human society. This is confusing the effect with the cause, as it is a societys culture that determines which aspect of human nature dominates according to Deweys argument. So the basic idea of Deweys first chapter is that if political freedom is to be maintained it is through culture and not through the individuals, as they are themselves motivated and to a degree "controlled" by culture. The exaggeration of one aspect of human nature as the sole motive behind human behavior is itself culture driven; this is well supported by historical facts. For every age gives rise to a motive of behavior that accords with its cultural needs. And the example Dewey gives is England during the industrial revolution; as the economic situation was intense it gave rise to the belief in a sole human motivator that is in harmony with this economical situation. 2- In chapter 2, Dewey discusses the differences that lie within the same society, how they might affect society and how they are not an objection to his theory of cultural domination over human behavior within society. In this chapter he concludes that: "No estimate of the effects of culture upon the elements that now make up freedom begins to be adequate that does not take into account the moral and religious splits that are found in our very make-up as persons. The problem of creation of genuine democracy cannot be successfully dealt with in theory or in practice save as we create intellectual and moral integration out of present disordered conditions." This perhaps sums up

Canterbury Tales Essay - Marriage and the Role of Women in the Wife of

Marriage and the Role of Women in the Wife of Bath’s Prologue  Ã‚   The Canterbury Tales, begun in 1387 by Geoffrey Chaucer, are written in heroic couplets iambic pentameters, and consist of a series of twenty-four linked tales told by a group of superbly characterized pilgrims ranging from Knight to Plowman. The characters meet at an Inn, in London, before journeying to the shrine of St Thomas a Becket at Canterbury. The Wife of Bath is one of these characters. She bases both her tale and her prologue on marriage and brings humor and intrigue to the tales, as she is lively and very often crudely spoken. Her role as a dominant female contrasts greatly with the others in the tales, like the prim and proper Prioress represents the argument for virginity, whereas the Wife upholds the state of marriage. Women were very much perceived as second-class citizens in the Fourteenth Century, they were rarely educated and had little status in society. In contrast, the two female characters in the book are from areas of society where it was possible for women to have influence probably as these characters would hold more interest for his readership. The prioress was undoubtedly the most powerful person in the nunnery and the Wife’s position as a weaver would gain her respect and power although it is implied that she achieves this through other means. Through the Wife Chaucer shows how women achieved authority through marriage, using humor typical of modern mother-in-law comedy. His tongue in cheek approach shows how the Wife controls her husbands, by terrorizing them so that each were "ful glad" when she "spake to hem faire". The reason for the Wife’s cruel treatment after marriage was that she no longer needed "to winne hir love, or do... ...ant in the modern day church. The aspects of marriage portrayed in the Wife of Bath’s prologue feature heavily around sexual pleasure and wealth. Her description shows the struggle for power causes conflict, occasional violence and abuse; all the while she is justifying her lifestyle and fighting for female equality. Despite no fidelity, love, or trust as deceit and affairs that seem to be commonplace the Wife of Bath ‘s description of married life is very much a comical one, which she does seem to enjoy especially if she achieves fulfillment. Altogether Chaucer’s portrait of 14th Century married life is at best a humorous battleground for independence, wealth and pleasures of the flesh. Works Cited: Chaucer, Geoffrey.

Advertising Causes And Effects Essay

Advertisement industries have affected the world for decades up until these days. We can see those flashy, catchy and colorful advertisements everywhere especially through mass media. United States was reported as the largest and creative advertising market in the world. Some people thought that advertising does not affect much on their lifestyles and some would just making assumptions that advertisements can cause negative effects to consumers especially when it is related to the product’s quality. However, we cannot be too judgmental on advertising industries because they have their own benefits. It is very important to take note that advertising does have its own positive side to country’s economy, companies and also society. Firstly, advertising can bring benefits to the economy. This is because, advertising generate more jobs comparing to the others. They offers diversity of careers option like writers, authors, artist, editors and others. According to the World Advertising Federation (WFA), US advertising generate 18.2 million out of the 126.7 million jobs in that country (2008). Besides that, advertising contribute a huge share on the country’s economy. Every advertisement that has been produced, need to pay certain amounts of taxation in order for them to publicize the advertisement to the public. According to the Wall Street Journal, Hungary adopt tax as high as 40% on annual advertising (Feher, 2014). Next, the price of the product will also be reduced through advertising. Most of the companies nowadays are more focusing on the quality of their products instead of gaining profit. One of the strategies that advertisement industries applied in their public relation are by helping the customers to understand more about the products and the company (McNamara, n.d ). Hence, the economy of the country can really be boosts up through advertising. In addition, the society are also affected with the benefits of advertisements. Through advertisements, people can be aware about commercial products and calamities that happened in the world these days. For example, the advertisements that shared on health drinks and toiletry products can generate awareness about health and hygiene to public (Kannan, 2013). Besides, some companies that produce cosmetic products will promote their products by comparing their product and advertise them through mass media.  Consumers would have varieties of options to choose by reading or watching those advertisements since 84 percent of mobile users in Malaysia tend to click on mobile advertisements in order for them to find new products and information (Siti Shameen, 2014). Moreover, people can also express their feeling through advertising. This has seems to be happening in the United States where they allow people to show on their supports regarding the sensitive issues like politics, religion and races. For example, in New York and San Francisco, they have the advertisement that shows Muslims are ‘savages’. (Badger, 2012). Besides, advertisements can also be used to inform public about social events and performances that are going to be held in the future. For instance, the Ad Council, a non- profit organization in the United States had sponsored many public service announcements like their famous ’Loose Lips Sink Ships’ where they run to promote national security during World War II (Morley, 2015). Therefore, advertising brings benefits not only for the consumers but also the society. Next, advertising has made a huge impact on companies. The companies can now create maximal profits through advertising. By having their advertisement airing frequently through pamphlets, mass media and others, they would attract more customers in buying their products. When they are attracted in looking at the advertisements, they would be intimidated in buying the products thus causing the rise of the company’s profit. When the advertisements are being aired through the internet, they would reduce more on their capitals thus, maximizing on their profit (Wright,2015) Besides, advertising also encourage the companies to compete and provide new products. When each of the company produce different types of new products with more improved qualities, the other companies would feel challenged thus producing a better quality of the products. By advertising, it can also improve the company’s public image among the consumer. This is because when a company produce advertisements through mass media, the consumer would assume that the product is quality-proven. It all depends on the company’s decision in conveying the message whether in a good way or the opposite (Thompson, 2014). Thus, advertising contribute to the advantages of the companies. In a nutshell, advertising brings advantages not only for the economy but also to the companies and the consumers. This is because, advertising can bring maximal profits to the company by generating more customers in buying their products. Besides that, the consumers would also have the power to decide which product suits them well through the exposure that they get through advertisements. Next, the country’s economy can also be generate by providing more jobs in the advertisements industries. Therefore, advertisements brings benefits to the world’s economy. 1. Siti Shameen, M.K.
