Sleep, Dreams and REM Sleep Behavior Disorder :: Biology Essays Research Papers

Sleep, Dreams and REM Sleep Behavior Disorder The discovery of rapid eye movement (REM) sleep suggested that sleep was not, as it was thought to be, a dormant state but rather a mentally dynamic one. Your brain is, in fact, very active in this state, almost to the level at which it is when a person is awake. Yet during this active stage in which most dreams occur, the movements of the rest of the body are completely stilled. To imagine this paralysis during dreams not occurring is a frightful image, since in many cases dreams are violent and active. When the neurotransmitters that control the movement of the body do not work properly the person develops REM sleep behavioral disorder (RBD). While we are sleeping the sensory world is essentially revolving around us without our knowledge. Our senses of hearing, touch, taste, sight, and smell no longer function as they do when we are awake. Except for the threshold for each of these senses that each of us has while we sleep, our inner systems are working essentially free of input from the outside world. And yet people are able to have vivid dreams. The cortex can only pass into sleep mode with the help of the are of the brain called the thalamus. The thalamus is one of the two structures that make up the diencephalon, the lower part of the fore brain. Its main function in mammals is as the relay station of sensory information its way to the cortical center. Specific regions of the thalamus, as well as different nuclei process different sensory information on its way to the cortex. In normal sleeping patterns a person usually passes through five phases of sleep, the fifth being REM. The sleeping human passes cyclically through these five phases throughout a night's rest. These phases can be defined in electrical activity of the brain; much like the activity of the heart is often defined. The technique of measuring the electrical activity of the brain is call Electro-encephalogram, or EEG. When the electrical events of a person's brain are graphed on a electrical magnitude versus time axis the graph of a person who is in different stages of being asleep or awake appear to have different levels of electrical activity occurring in the brain. (See (14)) During the cycle of the phases each lasts for a different period of time during the time we are sleeping.

Confronting Inequality by Paul Krugman. Essay - 791 Words

In his article Confronting Inequality Paul Krugman is asserting the fact of high socioeconomic inequality in the United States, while demonstrating its consequences and the variety of statistic evidences upon it. He is depicting modern American society where we have a huge gap between economic elite and lower-and middle-income classes. There is a time for a Great Moderation reforms that will bring a socioeconomic equality.

As we can see from the s tatistic the hedge fund tax loopholes costs the government more that $6 billion a year, what is enough to provide health care for three millions children. The arithmetic of the equalization demonstrates that tax-cut rollback can pay for implement of universal health care, but the necessary reforms must go through the government. Universal health care is one of the key aspects of being truly middle class society. The U.S. are compared with other countries and we can see the we have top U.S. tax rates are low compared with those in Europe. And consequently, we see that the inequality strains the bonds within the society itself, people less trust the government or each other. While social trust is crucial in having a stable political situation in the country: very high executive pay used to provoke public scrutiny, congressional hearings, and even presidential interventions. So it comes a turn of the inequality of market income. I agree, that the first step was already made by rising the minimum wage, but it`s no enough.

The Syrian Civil War - 2000 Words

The precursor to the Syrian Civil War dates back to when Hafez al-Assad, a Baathist, seized power through a coup d’à ©tat in 1970. Since 1970 Syria is a semi-presidential republic, with Bashar al-Assad as the current president and head of state. Conversely, Hafez groomed his charismatic son, Bassel, as the future president of Syria, while Bashar lived under the shadow of his elder brother. Bashar in comparison to his brother was an intellectual and exhibited a quiet and reserved demeanour. However, in 1994, Bassel was killed in a car accident, and as a result, Bashar, who was a physician specialized in ophthalmology, was recalled back to Damascus from England. Bashar was then quickly enrolled in a military academy in Homs and rose to the†¦show more content†¦Antigovernment movements broke out in early 2011 with the Arab Spring. The Syrian government has used brute force, even illegal chemical weapons, to suppress protests. Armed resistance to the regime arose in the summer as soldiers defected from Assad and established the Free Syrian Army consequently. The main belligerents consist of the Syrian Army, the Syrian National Defense Force, Shabiha, Hezbollah, and Iran, whilst the opposing parties consist of Syrian National Council, Syrian National Coalition, Islamic Front, Mujahideen, Al-Nusra, Syrian Kurds, and Islamic State of Iraq (ISIL) and the Levant. International reactions in regards to the Syrian Civil War vary from support of al-Assad’s regime to advocating the government dissolve. Currently, the Assad regime controls Damascus, and most of the provincial capitals in the West of Syria, whilst the rebellion has large swathes of land to the East and North. The Syrian Civil War has evoked divided opinion from international leaders, with Western powers such as the United States, supporting the rebels, whilst superpowers Russia and China support Assad’s regime. As a result, a contemporary proxy war has emerged. This paper will e xamine the different perspectives global leaders have on the Syrian Civil War, and consequently their actions towards the conflict. The Western powers discussed in this treatise are some of the key nations enveloped in the conflict: United States of America, Israel, and

Executive Compensation A Pay Ratio Rule - 1083 Words

CEO’s Compensation Nola Ward Independence University Introduction More than five years ago the Securities and Exchange Commission was told to issue a pay ratio rule that companies that are public must disclose how their median worker’s pay compares to their chief executive officers pay. Liberal advocacy groups and unions like the pay-ratio rule when corporations dislike it; because of the point of public shaming. CEO’s will look greedy and graspy when the world know that they make hundreds of times more than their median level employees, which in turn the corporate boards may be forced to cut the bosses pay and raise the workers. It makes sense to focus on how CEO’s pay is determined instead of obsessing on how much they earn.†¦show more content†¦Because of their compensation sets the pattern the criticism particularly focus on the CEO’s high pay as well. Just like the previous criticism, there are current complaints which focused on at least two issues: Executives are paid too much and becaus e the connection between executives current incentive-pay schemes are flawed. Because of these issues the company performance at best is mixed and at worst has led to a series of dysfunctional behaviors (Lorsch Khurana, 2010). As the pay gap between chief executive officers and American workers of public companies grow; the question has aroused as to what drives the pay of the CEO’s and what’s behind the disparity. It is a known fact that it is a big disparity between the pay of other worker and the CEO pay in corporate America but what is the reason this disparity exists? The first major justification is an incentive for performance that is put forth by corporations; this helps explains the CEO pay level. They thought in order to attract the right candidate who will impact the performance of the organization is that they have to pay big. If this happens the shareholders of the company can get a better return on their investments. What has been justified as comp ensation for executives is to provide them with some form of stock grants as a form of incentive with

What Did I Learn about Cell and DNA Free Essays

A cell is both the smallest as well as the most important unit of every living being, plant or animal. There are specialized cells in the body which carry out different functions. However, all cells are the same in that they all have a plasma membrane to protect them and determine what enters the cell and what leaves the cell. We will write a custom essay sample on What Did I Learn about Cell and DNA? or any similar topic only for you Order Now Inside the plasma membrane is the cytoplasm, a gelatinous mixture made up of water, fats, proteins, sugar, and other minerals. Most of the cell’s metabolism occurs in the cytoplasm where what are called the organelles work together to perform the metabolism. The nucleus is in the center of the cell. It controls the cell’s operations, such as directing cell division and determining the function of the cell. Only eukaryotic cells have a nucleus. The nucleus contains chromosomes, rod-shaped structures in the nucleus that contain genes, or regions of DNA. Within the cell is a reticulum, or network, of canals to manufacture proteins for the cell to use called the endoplasmic reticulum. Large proteins are made from smaller proteins, a process called anabolism which takes place on the ribosomes of the endoplasmic reticulum. Also in the cytoplasm is the mitochondria, known as the power plants of the cell where foods are burned to release energy in the presence of oxygen. This organelle is where ATP is made. This chemical process is known as catabolism. Together with anabolism they are combined to make the process of metabolism. There are two kinds of endoplasmic reticulum, rough and smooth. The rough ER has thousands of ribosomes attached to it, and the smooth ER does not have any ribosomes because it does not make any protein. Another organelle is called a Golgi body. This is where the enzymes in a Golgi body work to make the proteins and lipids either assemble or break down the lipids or the carbohydrates. Proteins are transported in what is called a vesicle from the ER and are changed to their final form. From there they are either carried to the plasma membrane or the lysosomes. A lysosome is a vesicle that is in charge of digestion. They are filled with enzymes that easily break down many proteins, carbohydrates, and much debris. Cells are different in their functions and their shapes as well. However, all cells whether plant or animal, are the most important unit of every living thing. Every cell contains a plasma membrane, cytoplasm, and organelles which carry out the functions of that cell. Only eukaryotic cells have a nucleus, a double membrane where the DNA is located. The organelles of a cell work together to  perform metabolism, the combination of anabolism and catabolism. How to cite What Did I Learn about Cell and DNA?, Papers

Biotechnology Genetically Modified Foods Essay Example For Students

Biotechnology: Genetically Modified Foods Essay Throughout the advancing technology of today, human culture is becoming revolutionary with science and all of its components. Genetically modifying foods presents positive opportunities in agriculture and human health. Furthermore, more scientifically advanced modifications that select genetically superior plants, have enhanced the yield of crops, improved storability, and increased disease resistance. To simply remove genes from one organism and transfer them to another is generally harmless if we take appropriate precautions. This often debated issue holds many objections. Moreover, one may claim that modifying genes at all is unnatural and evaluates a sufficient risk to many different organisms and species. However, the current technology we possess provides us with the capabilities to go beyond our limits. Why draw the line here? Genetically modifying foods presents positive and beneficial opportunities. In most cases, we are not eating those genes. By the time a genetically engineered corn plant has been processed into corn oil, virtually none of the genes or the proteins they produce is left in the food. Transferring genes from one plant or animal to another provides an advantageous outcome to this production. A better resistance to weeds, pests, and diseases is produced as well as better yield and a more efficient use of land. Additionally, altering genetics in foods contributes to a better texture, flavor, and nutritional value of a product. Therefore, there is a longer shelf life and less herbicide or other chemicals are used in the production of genetically modified foods, which provides a healthier option and an increased selection for the consumer. Biotechnology is going to help solve problems that we face going into the next century such as reduction of allergies, development of more nutritious foods, and an increased nutritional production to feed a growing population. Subsequently, changing one or two genes does not make a food unacceptable. Religious and vegetarian groups would object to genes from some species, while adequate protection can be given with labeling the product. Ethically, one may argue that it is radically useless to modify foods genetically or that agriculture is already too technological and it will only progress more negatively. However, it is likely that increasing numbers of genetically modified foods will emerge in the near future with more variety of modifications and associated benefits. Generally, genetically modified foods will affect the lives of most people in the areas of food, medicine, and environmental protection as it meets the modern technology of today. This advancing technology requires careful regulations to ensure that there is no threat to human health in introducing this production system. Proper labeling, accurate product information, and the provision of species are some of the measures that one can review as a means of ensuring public confidence in the safety of genetically modified foods. Additionally, this is also effective as a means of providing those with objections to the technology with a means of avoiding these foods. Fundamentally, by altering the genes of specie for the benefit of human race and its development is simply not changing the rules in life, but rather it allows us to progress into a new revolution of advancements for the future. .
