Hemispheric Specialization: Effects of Drugs on the Brain

Hemispheric Specialization: Effects of Drugs on the Brain NANA KOFI BONSU AKUFFO LANCASTER UNIVERSITY INTRODUCTION The human body is divided into many parts called organs. All of the parts are controlled by an organ called the brain, which is located in the head. The brain weighs about 2.75 pounds. The brain is made up of many cells, and I the centre of the body. The brain sends messages to all the other parts of the body (â€Å"The Human Brain.† 123HelpMe.com. 19 Feb 2015). The human brain is seen to be in a spherical form. A hemisphere is half of a sphere, so this means, the brain divided into two parts or hemispheres. There is the right and the left. These hemispheres appear to be identical, but closer examination reveals that they are highly specialized regions that serve different functions. The left hemisphere enables our ability to express ourselves in language. In over 95% of right-handed people the left hemisphere is dominant for speech. The figure is somewhat lower for left hander’s, approximately 70%, but still highly significant. The left hemisphere is better than the right at recognizing sequences of words and letters. It controls our logic, our reasoning, and our analytical thought processes. It can focus on details, however it has difficulty comprehending the whole picture. The perceptual functions of the right hemisphere are more specialized for the analysis of space and geometrical shapes and forms, elements that are all present at the same time (not so sequential like language). The right hemisphere is the creative half, it can see the whole out of parts, that is allowing us to connect puzzle parts together. The right hemisphere also plays an important role in the comprehension of emotion. However, the control of drug intake from childhood stages to late adulthood increases gradually in life. Even for medical purposes, the intake of drugs may not just help a patient recover but can also have other negative side effects that later on in life reveal themselves. Drugs affect brain pathways involving reward, that is, the dopamine system in the reward pathway. Within seconds to minutes of entering the human body, drugs cause dramatic changes to synapses in the brain. LITERATURE REVIEW Hemispheric specialization refers to the study of cognitive functions, dividing them up by the hemisphere of the brain responsible for them (www.ask.com/ science/define-hemispheric-specialization). Cognitive function refers to a person’s ability to process thoughts.  Cognition  primarily refers to things like memory, the ability to learn new information, speech, and reading comprehension. In most healthy individuals the  brain  is capable of learning new skills in each of these areas, especially in early childhood, and of developing personal and individual thoughts about the world. The brain has two halves orhemispheres. The two sides look like mirror images. This is calledbilateral symmetry. The wordbilateralmeans two-sided, while symmetrymeans the two sides look the same. So bilateral symmetry refers to the fact that the brain consists of two halves that are nearly mirror images of each other. Some function locations vary depending on the dominant hand of the patient. In general terms, literary functions are focused in the left hemisphere, particularly in right-handed people, while creative and figurative functions center in the right hemisphere. Also well-known is that the brain isâ€Å"cross-wired†, with theleft hemisphere controlling movement on theright side of the body, and theright hemispherecontrolling theleft side of the body. Most, but not all, of the different structures, lobes and organs of the brain have a left and right hemisphere element, andcommunication between the hemispheresis achieved by means of a thick bundle of nerve tissues known as thecorpus callosum, which effectively makes a full brain out of two half-brains. HANDEDNESS AND LANGUAGE PROCESSING It was the French physiologistPaul Brocain the 1860s (as well as his less well-known countryman and near contemporary,Marc Dax, almost 30 years earlier) who noted that, at least in general terms, a person’s handedness tends to indicate aspecialized hemisphere on the brains opposite side, so that a right-handed person probably has a left-hemispherelanguage specialization, andvice versa. Indeed, for almost a century, until theWada test(a technique involving the anaesthetizing of one side of the brain using a drug such as sodium amytal or sodium amobarbital) was introduced in the 1960s, a person’s handedness was just about the only clue an operatingneurosurgeonhad about which hemisphere of a patient’s brain was probably the one specialized for language. Following Brocas findings, it was initially assumed thathandedness and the hemispheric dominance of speech processing were inextricably and intimately connected. However, it soon became apparent, even to Broca, thatexceptions and mismatches existed, and that perhaps the association wasnot as fixedas he had initially thought. Although the incidence of right-hemisphere language dominancedoesincrease more or less linearly with the degree of left-handedness, it turns out to be not quite as simple as that. In fact, after the work of Springer Deutsch, Damasio Damasio, and others in the 1990s, we now know that, although about 95% of right-handersdo haveleft-hemisphere dominance for language functions, only around19% of left-handershave right-hemisphere language dominance, with another20%or so processing language functions inboth hemispheres(the incidence of language distribution inambidextrous peopleis broadly similar to that found in left-handed people). Other studies report percentages for left-handers of 70%, 15% and 15% (rather than 61%, 19% and 20%), but the finding all suggest that, perhaps unexpectedly, some60% 70% of left-handers process language in the left hemisphere, just like right-handers. Indeed, around 93% of all people have left hemisphere language dominance (http://www.rightleftrightwrong.com/brain.html). One half-brain is not â€Å"logical† and the other â€Å"intuitive,† nor is one more â€Å"analytical† and the other more â€Å"creative.† Both halves play important roles in logical and intuitive thinking, in analytical and creative thinking, and so forth. All of the popular distinctions involve complex functions, which are accomplished by multiple processes, some of which may operate better in the left hemisphere and some of which may operate better in the right hemisphere, but the overall functions cannot be said to be entirely the province of one or the other hemisphere. And far from having separate lives, the two halves work together. They are not isolated systems that compete or engage in some kind of cerebral tug-of-war; one is not an undisciplined child, the other a spoilsport that throws schoolyard tantrums. Rather, as we have stressed, the brain is a single, marvelously complicated, and deeply integrated system. Like those of a well-maintained bicycle, the parts of the brain do have different functions but, like the parts of a bike, they are designed to work together. Finally, as we discussed earlier, there is solid evidence that none of us relies primarily on one or the other hemisphere. We all use all of our brains; none of us are truly â€Å"left-brained† or â€Å"right-brained.† DRUG ADDICTION A drug is, in broadcast terms, a chemical substance that has biological effects on human beings and animals. In  pharmacology, a drug is a chemical substance used in the treatment, cure, prevention, or diagnosis of disease or used to otherwise enhance physical or mental well-being.  Pharmaceutical drugs  may be used for a limited duration, or on a regular basis for  chronic disorders. Recreational drugs  are chemical substances that affect the  central nervous system, such as  opioids  or  hallucinogens. Alcohol, nicotine, and caffeine are the most widely consumed psychotropic drugs worldwide. They may be used for effects on  perception,consciousness,  personality, and  behavior. Many recreational drugs are also medicinal. Some drugs can cause  addiction  and habituationand all drugs have  side effects. Many drugs are illegal for recreational purposes and international treaties such as the single convention on narcotic drugs  exist for the purpose of legally prohibiting certain substances (http://en.wikipedia.org/wiki/Drug).

How can ICT Help Special Needs Children Integrate Themselves in Society?

How can ICT Help Special Needs Children Integrate Themselves in Society? â€Å"We are seen as ‘abnormal' because we are different, we are problem people, lacking the equipment for social integration.† (Brisenden, 1986) Not so long ago, society was to blame for secluding and cutting off special needs people, from complete partaking in society and as a result, these impaired people ended up demoralized and feeling inferior to others. Today we know that special needs people, try their best to learn to communicate with the rest of society. The problem is not whether they succeed or not, the problem is; Are we, as part of society, doing enough effort to help them in their lifetime struggle? The International Society for Technology Education (ISTE) has recently initiated learning environments which integrates Computer Technology and Good teaching in order to increase the motivation and self-esteem of special needs students. Researchers following closely the program have stated that Computer technology enhances these children's ability to solve problems and make decisions, they build a positive self-image, they are excited about learning and thus they become better citizens. One major reason for using ICT was to reduce the large rate of dropouts. Researchers have concluded that Children with Literacy Problems (mostly dyslexics), often lack behind the rest of their class, give up on learning and end-up as school dropouts, feeling unable to fit in a society. ISTE has created a learning program called Video Disk Spaced System. This proved to be highly successful as it was not only a support for these children, in order to keep up with the rest of the class but it also managed to promote that positive self-image concept. Computer technology motivated these kids and they in turn appreciated the potential of ICT in a learning environment. Results have shown that ICT did help these special needs children as the dropout rate decreased to three times lower than the natural average. ICT can also help physically impaired children by fulfilling their dreams. In example Sharita a physically disabled child dreams to become a writer but unfortunately she cannot move her fingers. Computer technology has helped her fulfil her dream by devising a long extended stick in the form or a finger with which she can press the letters on a computer keyboard. Another concrete example regarded Megan who is unable to speak and write because she has Cerebral Palsy, however through ICT she was awarded as the Top English Student in her class. A Light Talker was devised, which is basically a matrix of letters and phrases. Through the use of a head switch (because Megan can only control the movement of her head), she can stop vertical movements of light at the desired row and stop the horizontal movement of light at the desired letter or phrase. Through ICT Megan is thus able to communicate with tremendous effort. However one has to keep in mind that without this device Megan can neither develop her intellectual potential, nor can she express herself as a part of society. Through the examples discussed above one can realise that by Integrating Computer Technology with learning, these special needs children are becoming more eager to learn, they are being provided with new ways to manipulate their environment in order to communicate better with the rest of society, barriers are being blown away and a variety of new worlds opened up, all by the use of Computer Technology. Apart from all this, ICT has provided them with what any individual wants that is their independence. Illegal Copying of Intellectual Property Alert!! You may be Unaware of Committing Computer Crimes†¦ * What is Illegal Copying? A widely used term which means the same as illegal copying is Copyright Theft or Copyright Infringement. Copyright theft occurs when making use of protected work such as: software programs; another writer's text; movies; sounds; and images, without actually paying the required fee for authorisation. * Illegal Copying and the Use of Computers: The use of Computers has made the act of copying far easier and handier than in the past. Burton (1996) argued that the Internet is one big copying machine that is basically ridiculing copyright laws. * What is considered as Copyright Violation? Software Piracy – Software copying such as copying a program from one diskette to another. Network Piracy – Distributing unauthorised copyright materials in digitized form ex: record companies have protested against sending unauthorized copies of digital recordings over the internet. Plagiarism – Illegal Copying of Academic Property: such as another writer's text, journals etc. Interpreting and presenting them as one's own. Ownership of media – Altering images, movies and sounds. * Plagiarism: Illegal Copying of Academic Property: You as a student may think it is harmless making one copy of an Academic Software program while the teacher is looking away, but you need to keep in mind that if all students should think the same as you think, then one single act of software piracy, will be then multiplied thousands of times. In addition to this if you are caught copying illegally Scholar property, you may end up sued by the school itself. Interpreting other writers' texts (found while researching for assignments) and presenting them as your own is also considered as a criminal offence and one can end up permanently suspended from school. * The Results of Getting Caught : If you are caught using pirated academic software, you could: Face civil fines (which you don't afford and your parents may want to kill you) Endure humiliating publicity End up with a criminal record (which affects you future) * A Word of Advice: It is not ethical to illegally copy any intellectual property nor is it worth risk taking because there is a high percentage of getting a computer virus and worse the risk of getting caught!

How to Make the Perfect Sandwich Sandwiches today as we know it, are just slices of ham and cheese put together with two slices of bread. The dictionary definition of sandwich is two or more slices of bread with layer or layers of meat, cheese or other various condiments. But where did the word ‘sandwich’ come from? You and I both know that a sandwich does not contain sand in it. In fact sandwich is actually a title of an English Nobleman, John Montagu, The Fourth Earl of Sandwich. John Montagu was gambling late at night, when he was hungry, he asked the waiter for slices of meat between two slices of bread so his fingers wouldn’t be greasy and it would keep the cards clean. But since John Montagu gambled very often, he would order it every time. It soon caught on to outsiders, where eating sandwiches were the perfect food while gambling. The perfect sandwich should be slices of bread with anything you like in it; it should be just the way you like it. Sandwiches can be eaten for breakfast, lunch, dinner and even snacks. How big the sandwich is can determine whether it should be for breakfast, lunch, dinner, or snack. For example a basic grill cheese sandwich containing, two slices of bread and one slice of cheese is small and light, therefore it should be snack. A bacon, egg and cheese sandwich is one hearty meal, but it has breakfast written all over it. Bacon, lettuce and tomato, sounds familiar? Of course, the B. L. T. is one of the most famous sandwiches out there. The B. L. T. can be eaten as breakfast, lunch, or dinner all depending on the amount of bacon, lettuce, and tomatoes you put in it. My all time favorite would have to be the classic turkey sandwich. And no, you do not have to wait until there are leftovers from Thanksgiving. The first thing you would need to do is buy turkey. No, not the entire turkey! You can buy sliced turkey from your local supermarket or deli. Usually I prefer honey-glazed smoked turkey, which contains a sweet smoky flavor. Next you would have to buy bread, what kind of sandwich would it be without bread? I would suggest whole wheat cinnamon raisin bread, why? You have to taste it to see for yourself, even if you run out of materials to make sandwiches; you can most definitely eat this on its own. The next thing I would get is lettuce and tomatoes; they just add this fresh, crisp flavor to the sandwich. One last condiment I suggest getting is cheese, pepper-jack cheese to be exact. If you don’t like spicy foods, I would then suggest Swiss-cheese. If you dislike the holes, you can always get American cheddar or mozzarella. After you buy all the materials needed to make the classic turkey sandwich, start off heating a grill or a pan, use low heat. No need to oil or butter it because you would just be toasting the bread and melting the cheese. Take two slices of the whole wheat cinnamon raisin bread and put it onto the grill or pan side by side. Next take two slices of the pepper-jack cheese and put one slice on each slice of bread. Turn off the heat once you see the cheese melting slightly. The next step is the fun part, â€Å"have it your way†, put turkey, lettuce, tomatoes, cheese or even bread on top of the melted cheese. Go ahead stack them anyway you like it, but don’t forget to eat it. Don’t waste time! Our writers will create an original "Process Analysis" essay for you Create order

Persuasive Essay On Dancers - 1020 Words

Have you ever watched the Nutcracker as a ballet? Or seen a professional dancer dance? You probably thought of some of the things that they did were effortless. The truth is, it isn’t what you think. Dancers go through pain, stress, and shoes (Seriously!) to do what they do. There are a lot of people that think that dancing is easy, and I am here to set that straight. Let me start off by talking about the pain. Dancers go through a lot of pain. On average dancers get hurt about once every two weeks. That means that dancers, on average, get hurt about 26 times a year. Whether it is a tiny fall or breaking a bone, dancing is a foolproof way to hurt at least something in your body. Especially if you are on pointe. In a pointe shoe, you†¦show more content†¦They really just eat, sleep, study, and dance. They have an average of 7 hours of dance a day and, if they are in college, only get about 5-6 hours of sleep depending on their minors and majors. Their schedule is this way for a reason. Dancers that professionally do this or have it as a major, need to keep their muscles used to doing everything that they do. Try to think of it as playing music. If you learn a piece of music and then don’t play it for a week, the chances are, you probably forgot it. That’s why it is important to have dance classes every day. Dancers also have their schedule this way because of their performances. Most dancers usually have about 1 performance a week, which means that every day they need to buckle down and work. All dancers, for a performance, need to learn their dances, get fitted for their costumes, rehearse the dances, and have stage rehearsals at the place that they will be performing at. This happens usually all in one week. This doesn’t even include their other college classes that they may take. Now as I had said in the beginning when people see dancers dance, it looks effortless to them. This is only because dancers WANT to make it look effortless. That is their job. The dancers want to make it look graceful and beautiful, and that doesn t come with making weird faces or having it look like they are working really hard.

It noted that many bodies have various characteristics that make them different. Many of the early forensic advances took place in the 1700 and 1800s. In 1784 the physical matching of evidence began.

Shape ; strength nature of intermolecular interactions impact melting point temperature Melting Point as an Indicator of Purity ; In a pure sample, all surface molecules need the same energy to escape. Leads to a narrow melting point range. For melting to occur, surface molecules must have enough energy to break free. Stronger in termolecular interactions = more energy required for molecules to â€Å"escape†. Translates to a higher pm. ; In an impure sample, intermolecular forces are disrupted in the region of the impurity. Less energy thus required for surface molecules to break free. Crystal begins to liquefy at a lower temperature ; structural features that influence how molecules pack together impact melting point temperature symmetrical compounds typically have higher melting points features that disrupt crystal lattice lower melting point Next Week Experiment 2: Rationalization Melting Point A.

Question: What factors drive immigration? How does immigration policy affect the fabric of the American society? What role does immigration play in the American society historically, currently, and in the future? How would a border-free immigration policy impact the social and economic system? Answer: Factors driving immigration: Many of the factors which influence the migration are quite hard to judge. The social, economic, and the political factors are exceptionally much more difficult to predict it precisely; but judgements can be made which are based upon the current condition and situations. The ecological disruption is quite easier to pre-empt for the reason that there are a large number of bodies of scientific evidence which enables us to suggest that these factors may be an important cause for concern in the future. The environmental modelling, plus worsening of the food as well as the water security in so many of the countries, clearly states that the ecological issues have already begun to present complications and challenges all around the world. These ecological factors have got significant potential to become ever enhancing forces that influence the migration in the 21stcentury. Thus, among the most important the Socio-political, ecological and the economic factors, mainly drive the process of mi gration. Numerous numbers of domestic or the push factors can encourage or force an individuals to exit living in their home country and migrate (Aguila, 2011). Thus, stay and other conditions those are available in the other foreign states which are also called as the pull forces influences the people and lure them for the fulfilment of the goal to migrate. Immigration policy affecting the fabric of the American society: The Immigration policy has transformed the USA as a kind of nation since the entry of the first newcomers in almost last 400 years. Besides being a very strong demographic force which is responsible how the nation and its people became what they actually are at present, immigration has widely contributed too many economic, political and social processes which are foundational to the US as a nation (Berke, Jablonski, Krug Valentine, 2014). There are some who argue that the historically high removals increase public safety, the nations security and the law, while others support that the system carries along with very severe mankind costs to children, families, communities, plus the tears at the fabric of the US socially. The US has always been a nation of the people immigrants. The entry door at sometimes may not be completely wide open for the people who wish to immigrate in it, but on the other hand they are not completely restricted or shut as well (Pisani Perez-Batres, 2012). The present debate which concerns the wisdom of comparatively much higher rates of the immigration is in no sense a new one; it has stretched back even at times of the colonial inhabitants. Serious concerns about the immigration effects on the economical prospective growth of the natives born in the country, on the population growth, plus at the capability of the immigrants to settle themselves and live have always been on high concerns areas. Role of immigration: In the year 1994, the number of the legal immigrants was approximately 800,000, which was considerably very small as compared to the number in the peak year of the 20th century which witnessed around 1.3 million immigrants in the year 1913. Also, the local resident population has almost grown by 3 times in the twentieth century, the immigrants in the early decades showed much comparative higher proportion which was 13 immigrants/1,000 residents in 1913, as compared to 3 immigrants/1,000 residents by 1994 (Battisti, 2014). The immigration then played much greater task in the population growth in respect to the eight years ago: it nearly was almost 37 percent of the total development, partly as a matter of fact due to the fall of the fertility rates of the residents. Apart from that the legal immigrants admitted/applied for PR which stands for the permanent residence, In 1994 some 21 million visitors were admitted for short stays visas, which included tourists, students, short-term employed employees in the international companies. Most of them do not stay for tenure which may be just a few weeks, while many of them live in the US for so many years; some even broke the legal rules and stayed much more than the allowed time (Wong, 2007). Many of the Americans are of the belief that free or easy immigration shall destroy working class citizens to live peacefully and earn a livelihood. They even believe that allowing open and free immigration to the soughing immigrants can put the decent as well as the hard-working Americans citizens out of employment opportunities. These US citizens also fear that the immigrants shall come out to work in America at much comparative lesser salary and provide equal output of the country, and shall ultimately kick their jobs away from them, But this is compulsorily required to be put into the minds of the local citizens that the freer trade and open borders which are made for the agreed immigrants is for the good of them as well (Rosenfeld, 2014). By enhancing the philosophy of this kind of free and open labour mobility, the country shall be benefitted on the account of productivity, entrepreneurship and also ingenuity. This open market for the immigrants labour shall at the end benefit the growth of the country and increase the production of the concerned country and shall also improve the standard of living of each and every residing there. Free immigration policy impacts the social and economic system: These issues are real complex researches, which involves the speculation and the public discourse which often run much more ahead of the conclusive research results. Without having any kind of fear in the history/past about the negative effects of the immigration on social fabric and any other sense of negative impacts on the country. Early and important findings conclude that some of the recent immigrants especially the Asian Americansclearly matches with the native-born whites in the fields of occupational and educational, although might not be equal in incomes. The residential segregation is yet another measure of the social difference (Rowthorn, 2008). Many of the recent immigrants like to stay and cluster in neighbourhoods of people from their home country, but this has also been noticed that some of them get mixed up in the local community of people and do not bother to compulsorily stay near and around their home immigrants as they are. The second important charge which impacts the immigration as far as the economy of the US is concerned is the economic theory. This theory states the possible effects which may happen on the employment plus the salaries of the domestic workers, along with the United States trade relationships with other countries all across the globe, the percentage rate of growth of the economy of the nation, and the prices which is paid by the residents to buy services and goods. In order to study these issues, the jury/panel depends on the theoretical insights which states the expected effects which would come out and also on the empirical estimates of the percentage of the real effects (Amit Riss, 2007). The profits for the local economy come from so many of the reliable sources that show that the effect of the immigration is a fruitful process of the country in concern. In concern to the production side, immigration freely allows the local workers to be utilized much more productive, especially for the production of such goods to which they are comparatively more accurate and efficient. The specialization in the consumption too yields a profit. It is assumed that the United States economy is clearly characterized by the continuous returns to the scalewhich is, economic, social growth in size and also the scale of the countrys economy, which neither reduces and nor enhances the labour productivity and the capital productivity in comparison to the current levels (Balestrini, Flood Flockton, 2011).
