Impact of Neurotransmitters on Physical and Mental Behavior free essay sample

Impact of Neurotransmitters on Physical and Mental Behavior Physiological Psychology November 20, 2011 Neurotransmitters are powerful chemicals that regulate numerous physical and emotional processes such as mental performance, emotional states and pain response. Virtually all functions in life are controlled by neurotransmitters. They are the brain’s chemical messengers. Interactions between neurotransmitters, hormones, and the brain chemicals have a profound influence on overall health and well-being. When our concentration and focus is good, we feel more directed, motivated, and vibrant. Unfortunately, if neurotransmitter levels are inadequate these energizing and motivating signals are absent and we feel more stressed, sluggish, and out of control. I’ve found four specific neurotransmitters that I’d like to write about, two because they affect me personally and the other two because they interest me. I take medications that impact both the GABA and Serotonin neurotransmitters and Dopamine and Norepinephrine because I find them fascinating. GABA (Gamma Amino Butyric Acid) is the major inhibitory neurotransmitter in the central nervous system.

GABA is considered a significant pain and moon regulator. As a personal experience with GABA, I take Klonopin for anxiety, which works on many receptors, including GABA to reduce stress, and another medication, Gabapentin (Neurontin is the generic name) for sciatic spasms, showing how neurotransmitters can affect different types of systems in the body. Serotonin is the other Neurotransmitter I have personal experience with, as I’ve been on medications called Selective Serotonin Reuptake Inhibitors (SSRI’s) since the age of 13. Currently I take Cymbalta, which helps increase the effects of serotonin, because when we have low serotonin levels we can suffer from sadness and depression, anxiety, panic attacks, reduced energy, migraines, sleeping problems, OCD (Obsessive Compulsive Disorder) or a reduced interest in sex. Dopamine is a kind of neurotransmitter called a catecholamine. Also in this category are Epinephrine (which I’ll be discussing next) and Norepinephrine. Dopamine is responsible for motivation, interest and drive. Excess Dopamine can be responsible for positive stress states such as being in love, exercising and sex drive. Low dopamine levels can be responsible for lack of concentration or motivation, reduced energy or difficulty initiating or completing tasks. Dopamine also has functions in muscle control and function. Recent studies have shown that low dopamine levels are found in people who â€Å"self-medicate†, such as alcoholics, drug addicts, gamblers smokers and overeaters. The last neurotransmitter I’ll be discussing is epinephrine, another catecholamine. Catecholamine is one of two classifications of the Monoamine Transmitter Substances. The other being Indolamine. Monoaminergic neurons increase or decrease activities of particular brain functions by modulating the function in widespread regions of the brain. Mainly, Epinephrine is a hormone produced by the central core of the adrenal glands, the adrenal medulla. Epinephrine is synonymous with adrenaline just as norepinephrine is synonymous with noradrenaline, and is considered a minor neurotransmitter compared to norepinephrine. Both epinephrine and norepinephrine affect noradrenergic receptors (more commonly referred to as just adrenergic receptors. Epinephrine regulates attention, focus, arousal and cognition while inhibiting insulin excretion and raising the amounts of fatty acids in the blood. Low levels of epinephrine can result in fatigue, lack of focus and difficulty losing weight while high epinephrine levels have been linked to sleep

Walter Ralegh And Death Theme Essays - Knights Bachelor,

Walter Ralegh And Death Theme The poems of Sir Walter Ralegh often deal with the issue of death and mortality. In some cases he directly deals with the issue, and others he uses vast metaphors in order to convey his message. For the most part, Ralegh takes a very bleak position on the issues of death and aging, but in some cases he takes a more optimistic view. Ralegh is said to have been a man who was a historian, soldier, courtier, philosopher, explorer, and of course a poet. The fact that he spent the last years of his life in a prison and was then executed for false charges of treason suggest that he knew the potential dangers of his activities and made a conscious decision to live the way he did. It is clear from his work that Ralegh did not know exactly what to think about the issue of death, and that he spent a great deal of time thinking it over. The result of this pressing question in Ralegh?s mind is a collection of poetry that covers the subject from several different perspectives. In Ralegh?s short poem ?On the life of Man?, he (as the title suggest) reflects on the meaning of human life. Ralegh makes the analogy of life being like a production on a stage. He compares the time spent in a mother?s womb to being like that of time spent in a dressing room where we prepare for what he calls a comedy. He gives no suggestion of any set structure in the comedy, but states quite clearly that heaven is watching and will be judging. He goes on to compare graves to drawn curtains. This is a very pervolant idea in American society where there is a cliche of the term ?curtains? for meaning the end or death. This particular poem is not very optimistic simply because there is nothing in it to suggest that life has any profound or special meaning which is something that people want to believe. Ralegh concludes this poem with the line: ?Only we die in earnest, that?s no jest.? From this it can be assumed that he thinks of his life a a comic time which should be enjoyed except for the end which is not funny at all. In Raliegh?s poem ?The Lie?, he also deals with the subject of mortality. The first line of this poem is ?Go, soul, the body?s guest?. It is clear that he sees the soul as a separate being from one?s physical body. In this scenario the body is simply the host of the soul, and it will leave upon the expiration of life. In this poem Ralegh is sending his soul on a mission to tell all of the people of the world that they are living a complete contradiction. He lists all kinds of things that he claims are not what they seem. There are lines like ?tell flesh it is but dust?, and ?tell nature of decay?. Basically he is commissioning his soul to go and tell the world what he feels that it needs to hear, and the soul is the perfect messenger because it can not be harmed. This is clearly his intent, and this is evident from the last four lines of the poem which read: Although to give the lie deserves no less that stabbing- Stab at thee he that will, No stab the soul can kill. This quote clearly shows the power and virtue of a soul. There are contradictions in this poem. On one hand it has a very bleak outlook on life, and suggests that humans are inherently immoral, but at the same time it touches on the sorrow and loss in the event of death. All the while the soul which is now free and untouchable is sent to be the bearer of bad tidings. This poem can be interpreted in more than one way, but there can be no doubt that Ralegh believed that death meant the soul could move on to better things which is not a pessimistic attitude. In Ralegh?s poem ?Nature, That Washed Her Hands in Milk?, he shows a much more negative sentiment towards the life cycle. He concludes this poem with the lines: Oh, cruel time! which takes in trust Our youth, our joys, and all we have, And pays us but with age and dust; Who in the dark and silent grave When we have wandered all our ways Shuts up the

Extra-curricular activities, like athletic achievements, musical involvements, writing for the school newspaper, joining various school clubs, the student council, summer camps, leadership trainings, among many others are just a few of the many activities that a student can get involved in to harbor more life experiences and to know where he excels at the most. Activities like those mentioned above do not only hone a student in one direction, but it improves the student’s social skills, especially in dealing with other people as these organizations exist because of its members, in thinking outside the box and letting their creative juices flow, in having passion for something that they believe in and in wanting to make a difference. These things are as important as being scholarly, because in college, you are not only being tested academically; you are being prepared for your encounter with real life in your chosen path the life after college.

Specialization and logrolling essays

Specialization and logrolling essays Specialization is the element whereby Congressmen become experts at the topics of the Committees or Subcommittees on which they serve. Through their prior knowledge and experience, they can grow to be more adept and knowledgeable about the legislative topic that they are dealing with. Over time, they gain respect as authoritative figures on the issue. This affects the legislative process by allowing those who are qualified to make key decisions on the committee level. It builds faith that the members of a committee know what they are doing, and can be trusted to make informed decisions. It also increases the influence of members of the committee, because other less-knowledgeable colleagues can turn to them for advice in regards to which way to vote on a measure. Reciprocity/logrolling is mutual aid and vote trading among legislators. Congressman A tells Congressman B that if A votes in support of X, then in return B will vote for Y. A member may vote with a colleague in the expectation that the colleague will later vote for a measure about which the member is concerned. This affects the legislative process by allowing Congressmen to build up coalitions of support for measures that would otherwise not garner enough support. It allows more pork-barrel spending to pass through, because other members may owe it to the representative of that area. Two ways that part leadership can influence the legislative process are by the strong influence that they have over the voting of members of their party, and through the vast amounts of control that they have over the legislative process in general. Members generally vote with their party. Party leaders do their best to get members to vote together. In the House, this has the effect of drawing members to the two political extremes. Party differences have become more pronounced, pitting Republicans against Democrats, and voting on major bills oft ...

There religion developed from a mixture of African culture of the slave who had settled in the sates. The early development of these religions was based on the need to have the Africans united in the foreign land. These realigns were based on the principle of truth, justice, righteousness, harmony, order and reciprocity. They were based on the need to have self sustainable and the notion of being self empowered in the foreign land. They had a sense of individual and communal appeal. The growth of these religions in Latin America could have followed amore direct root since most of them were prohibited. The prohibition of these religions made them stronger. They grew to be some of the most important sycretic religion in Latin America.Due to the prohibition of the practice of these religions, they did not make a nationals appeal but remained practice mainly by the individual African community that has started them. With time they came to be indentified with the Africans an identity that remains up to date. In light of this the national suppressing of these religions was different rand therefore they remained active in the country where they were more practiced. For example, Voodoo survived the religious assault in Cuba, Brazil, Dominic Republic and other part of Central America where it is practiced to date. Condobmle survived only in Brazil where it is practices up do date. Even up to date, there religions have remained racialized according to the community that started practicing them early. It was due to repression of these religion which made them stay limited to the African groups although there have been some degree of acceptance of the religion in the region.

Argumantative Resarch Paper - Feminism Research

Argumantative Resarch - Feminism - Research Paper Example Issues related to women rights and equality, which are yet to be achieved form the basis of justifying that feminism is still relevant in today’s world. Feminism is classified into three waves, which have taken place in different times. Each wave has had its main advocacy in attempts to fight for women equality in the society. Some of the objectives within each wave have been achieved while others have been unachievable, making the debate of feminism continue (Aikau et al 23). Feminism is derived from a Latin word â€Å"Femina†, which refers to a woman. The first wave of feminism was mainly focused on fighting for women rights in relation to voting processes. In early days, women were not given the right to vote during elections. In the UK, a feminist movement referred to as Suffragettes fought for voting rights of women. Members of this group engaged in violent demonstrations and even went to the extent of fasting to ensure that women got the right to vote. Today, it is difficult to see such violent feminism movement. During the early days of feminism, there was less support for feminist movements (Tandon 13). In relation to the first wave of feminism, many countries later accepted to allow women to participate in the voting process. Australia was among the first nations to allow women to vote, but other nations were reluctant is issuing their women the right to vote. Of most surprising is countries such as Saudi Arabia and Brunei still deny their women the right to vote. Considering that it is only a few countries, which still deny women the right to vote, one can sum up that the first wave of feminism has achieved its objectives. Therefore, feminism has lost its relevance as far as women voting rights are concerned (Aikau et al 28). The second wave of feminism began in the 1960s with the main objective of ensuring that men and women were equal in all aspects of life.
