Neurodegenerative Diseases Essay -- Biology Essays Research Papers

Neurodegenerative DiseasesA piece of well-oiled railcarry consists of an intricate and analyzable system thither are well-organized processes, mechanisms indoors the device work efficiently, and multiple processes function simultaneously to subsequently behave various functions. What happens when there is a glitch in the railway car? When there is something wrong, such as connections surrounded by intricate processes, which do not follow through, the machine fails to function properly. In some cases, there are not any adjustment or f eachback mechanisms. At that point, the damage can be permanent and the machinery is no longer salvageable. However, this can illustrate the interactions and processes within the complex machinery. The human brain can react in much the same way. Neurodegenerative diseases are blabbermouth signs of a glitch in the neural mechanical processes within the brain. Thus, pathological problems of the brain demonstrate how the brain controls movement and behavior. It is evident in the physical as well as emotional behavior. (5) It also illustrates the interaction mingled with the fundamental nervous system to the peripheral nervous system. There must be connections between neural activity within the brain and the rest of the central and peripheral nervous systems. One can also understand an illustration of the brain as being a box composed of interconnected little boxes. These integrated boxes in turn demonstrate the concept that, Brain=Behavior=Being. The purpose of this bear witness is to provide a general overview, as well as neurological overview, of the neurodegenerative disease, Creutzfeldt-Jakob Disease. In doing so, it will show how the brain proves to be the center of behavior and creates the individuals sense... ...The item that ones neural communication is severed and eventually shuts down all body function control, is evident. The knowledge that ones brain is riddled with holes due to a proteinaceous infective part icle is speculative. Although many think that an individual is much to a greater extent than mere neural connections, firing motor symphonies, neurotransmitters, and selective permeability, Creutzfeldt-Jakob disease puts a new spin on individual identity. Ultimately, the patients or their loved ones do not focus on the CJD facts and figures. Their reality is that an individual slowly disintegrates before their eyes, the sense of the Self is lost. kit and caboodle Citedhttp//www.cjd.ed.ac.uk/path.htmhttp//www.cjd.ed.ac.uk/intro.htmhttp//www.cjd.ed.ac.uk./lancet.htmDelcomyn, Fred.

Our Perceptions of Purpose in Nature :: Philosophy Philosophical Papers

Our Perceptions of Purpose in NatureIt will be objected that the book deals too much with mere appearances, with the line up of things, and fails to engage and reveal the patterns of unifying relationships which form the true underlying reality of existence. Here I must confess that I know nothing any(prenominal) about true underlying reality, having never met any..for my own part I am pleased enough with surfaces- in fact they alone seem to be of much importance. -Edward Abbey, Desert SolitaireThe primary distinction between humans and the rest of the natural world is our sense of consciousness and self-consciousness. We have very contrasting perceptions and filters than any other organism on the planet. Language, for suit, enables story cashiers to communicate and interpret their surroundings. However, there are limitations to relying on language as a primary neb for both internal and external dialogue- the verbal definition of things can often differ vastly from how they actu ally are. Words have cultural connotations and if the story teller is not careful, a meaning or significance that he did not intend will be assigned to the subject. Equally dangerous is the instance where a story teller actively searches for meaning in the natural world and uses language to clarify and articulate it. The roots of self-consciousness go as outlying(prenominal) back as the origin of humankind. Choice, morality, altruism, and a sense of purpose do not exist in a vacuum, they are as much the products of an evolutionary process as our physiological features. Until approximately 10,000 years ago, the only organisms to exist could be classified as model builders, meaning they are able to previse external change but do not have language or a sense of self. The Game of Life is a good example of the factors which determine the behavior of model builders, and nature in general. There are certain biological constants which limit the possible outcomes, but there is, in fact, no purpose or intentionality to the patterns which emerge. Edward Abbey explains this phenomenon in his novel Desert Solitaire- I am not attributing human motives to my snake and bird acquaintances. I recognize that when and where they serve purposes of mine they do so for beautifully selfish reasons of their own. (25)Story tellers, on the other hand, though part of nature as well, have much more interwoven factors to guide their actions- including emotions, consciousness, and language.
