The first step would be the stimulation whether it be air noises, water noises, music or someone coughing. The sound then travel to the outer ear where it is the reflected into the middle ear where it is amplified into the inner ear. The sound is then transferred through the viscous fluid in the cochlea. Inside the cochlea are tubes that are filled with fluid and hair cells. The hair cells are moved by the sound waves and become receptors for the primary auditory cortex. The cortex then processes the sounds into an interpretation. (University of Phoenix,…
Chapter 6 appealed to me because I can relate to the concepts and problems they considered. The one I related most to was the “alligator brain,” and how it takes over in stressful situations, which makes it difficult to remember things (p. 72). This is relevant to me because I do not stress about the test until I am taking the test and come to a question that I do not know. When this occurs, that question and…
Throughout the chapters, all the topics were clearly identified first, and then went into detail. The chapters did not jump from topic to topic every paragraph nor did each topic get dragged out too long. However, Pollan does have the tendency in some areas to get very technical to the point in which the reader might not understand. For an example, Pollan explains when corn’s photosynthesis and Carbon intake, he uses many scientific terms and explains processes in ways that…
I liked this chapter’s supplemental material; all the sources were brief and interesting at the same time.…
Many of the most watched television shows have a basis of crime, and murderers are almost always involved in these shows. What is rarely explored in these shows however is how the psychopathic killers become this way. Neuroscientist and Professor Jim Fallon has been studying the brains of psychopathic killers. He has developed three factors based on analyzing a plethora of brains to determine how psychopathic killers come to be. What this lecture helps open for exploration is why places with a small amount of violence stay that way, and violent places continue to produce killers.…

The Article is based on facts and applied research. Im not a scientist so I cant agree or disagree. However I do find it baffling that there is so much study of the brain that goes unseen. Its unbelieved to think how many hours, days, months researchers put in time to find or come up with different ways to uncover the brain. I think I…
I chose "Secrets of the Brain" by Carl Zimmer because it seems so interesting to learn how our brain works. In this article, Carl Zimmer writes about how our brain really works by taking the journey and witness it by having a brain imaging done on him. He goes to Martinos Center for Biomedical Imaging in Boston Harbor to perform this procedure. This procedure is called an "MRI" scan. Zimmer describes his experience during the scan and scientifically breaks down what is happening during the scan. Later on, he outlines the scientific discoveries and efforts of the scientific breakthroughs of the researchs done over the past. He talks about the brain research advances. He talks about how neuroscientists can start to identify differences in the…
Another thing I found to be very compelling was the reading about the Structure of the Cortex. It’s truly amazing what scientist have discovered about the human body. They are able to subdivide each hemisphere’s cortex into four lobes, separated by prominent fissures or folds. You have the frontal lobes…
It is important to understand the principle of complex communication because each neural network or function area is interconnected with and influenced by other networks in other regions of the brain.…
My favorite chapter is probably Of Microbes and Men because it is really interesting and hard to put down. She uses simple yet efficient syntax and diction which help to get her point across. She explains how all of the diseases we see on a day to day basis now have come from much simpler ones beginning hundreds of years ago. Nothing now is new, every day almost it seems like a doctor, nurse, or grad student comes up with the origin of some disease and a possible cure for it. Dr. Moalem suggests that there is one key microbe responsible for it which is not yet discovered. The evolution explained is not boring at all she finds a way to make it actually fascinating.…
In the first section, The Biology of Life, it sates that cells perform essential functions to sustain life, DNA contains instruction needed to direct the cells, RNA carries/ transcribes/ and translates instructions into proteins, and proteins do the work of the cells. In section two, Genes and Heredity, I learned that: Genes are segments of DNA, Traits are controlled by alleles, a person’s inherited potential is their genotype, autosomal patterns include recessive/ dominant/ incomplete dominant/ and codominant, and some inherited disorders are sex-linked disorders. In the third section, Gene-Environment Interactions, I learned that: Experience expectant/dependant focuses on the unique aspects of environment, genotype-environment correlates stress between child and the environment, genotype sets upper and lower limits, probalistic epigenesis refers to a process based of elements of probability and chance, quantitive genetics try to separate infuence of genetics, researches in genetics often study same-family twins, and intelligence go hand in hand with health problems. In the fourth section, The Physiology of Thinking and Feeling, I learned that: The basic components of the nervous system are central and peripheral…
NEUROLOGY INTRODUCTION: Nervous System- the body’s communication network - coordinates and organizes 3 Division: 1. CNS- central nervous system - made up of the brain and the spinal cord 2. PNS- peripheral nervous system - includes nerves that connect the CNS to the remote body parts - relays and receives messages 3. ANS- autonomic nervous system - regulates the involuntary function of the internal organs.…

The Central Nervous System is composed of the brain and the spinal cord and one of it’s primary functions is to send out messsages to the rest of the body. One chronic illness that affects the Central Nervous System is Multiple Sclerosis. Roughly 2 million people througout the world have been faced with this disease, and “in the United States, it is estimated that 450,000 people are affected, with 10,000 new cases per year” (Goodman & Fuller 772). This disabiling condition has been found more prevelant in the Caucasion race and there is a higher ratio of women diagnosed with MS then men.…
