Mapping the Brain, written by Sharon Begley, focuses on how the brain has specific tasks for each of the divided sections. In the article, Begley (1992) uses an analogy to explain how different regions of the brain have distinct roles and are in control of different tasks. Specifically, the brain is compared to a map. Begley (1992) declares, “[The maps] will show . . . where in the brain cognition, feelings, language and everything else that makes us human comes from” (p. 66). This means that…

her issues of forgetfulness, loss of words and feeling lost on certain occasions could be signs of a medical condition. Dr. Alice Howland pursues a neurologist Dr. Benjamin who through a series of memory tests, laboratory testing and a positron emission tomography scan confirms her diagnosis of familial Alzheimer’s disease (Brown, Koffler, Lutzua, Glatzer, & Westmoreland, 2014). The purpose of this paper is to critically analyse the theoretical and empirical perspective of the doctor-patient…

Over the past decade, health care costs in the United States have drastically increased, becoming a worldwide concern. This increase has negatively affected hospitals, clinics, and other health facilities, as well as the American people. In 2009, the U.S. spent over $8,000 on health services per person, while New Zealand and Japan spent one-third as much and Switzerland and Norway spent two-thirds as much. In 2009, Health spending in the U.S. was over 17 percent of gross domestic product (GDP)…

Topic: Understanding the Key Aspects of the Brain and the Nervous System. The entire human body activity relies on the brain function, in this first section of this report I will try to discuss the major structures, the functions as well as the major methods of studying the brain. The brain is in charge of all body functions, such as the ability to make decisions, do activities, learning and all everyday life stuff. The brain is situated in the skull protected by brain blood fluid. In the…

reflexes, sense of hearing and vison, also a simple task of getting out of the chair and walking across the room. A MRI and CT scan of the brain can also be done to see if there are any other conditions that may be adding to the symptoms. A Positron Emission Tomography (PET) can also be done. This is when doctors inject you with a low-level radioactive tracer. Then they follow the tracer with an overhead scanner. According to the being Mayo Clinic of Alzheimer’s disease, there is future testing…

Vaginal Cancer is a very serious disease that should be taken care of as soon as possible. This is a disease where the cancer cells are formed in the vagina. There is two main cancer which are not very common but are Squamous Cell Carcinoma and Adenocarcinoma. These next two aren’t so much common, vaginal melanoma develops in the melanocytes of your vagina and vaginal sarcoma develops in the tissue cells of the wall of your vagina. Squamous Cell Carcinoma forms in thin and flat cells…

sold as a racemic mixture of the isomers, but today the drug is also sold as with only d-threo-methylphenidate. Studies have shown there were few differences in binding affinities between the isomers (Markowitz). However, studies using Positron Emission Tomography in the human brain with radioactively-labeled methylphenidate have shown that therapeutic doses block more than 50% of the dopamine transporters, and significantly enhance extracellular dopamine (DA) in the basal ganglia. Recent…

PSYCHOANALYSIS DESCRIPTION The Psychoanalysis theory was formed by Sigmund Freud. Sigmund Freud was born in 1856; he became a physician in Austria. Freud was a medical doctor known as a neurologist, this type of a doctor which deals with disorders for which specialists could not find any bodily cause to this (Ciccareli & White, 2015, p. 10). For that reason, it was rather cogitated that the result must be in the patients mind, and then this is when Sigmund Freud began to examine the matter in…

cure for AD, regardless of its high prevalence among the elderly. AD is a neurodegenerative disease known to cause cerebral atrophy, tau pathology (neurofibrillary tangles) and β-amyloid plaques (Buckner et al., 2005). Through the use of positron emission tomography (PET), researchers have been able to observe a loss of nicotinic acetylcholine receptors (nAChRs) early on in the progression of the disease (Okada et…

Esophageal Cancer is the growth of a tumor in the lining of the esophagus, a hollow tube that connects the mouth to the stomach. The esophagus is a necessary organ that allows food to travel to the stomach where it can be broken down into nutrients for the body to use (Esophageal Cancer, mayoclinic.org). When discussing esophageal cancer, it is important to understand what can cause the growth of a tumor in the esophagus, what the potential risk factors are, the symptoms, how this cancer can be…
