Methods Used to Study the Brain Essay Example for Free

Methods Used to Study the Brain Essay A variety of procedures are used by psychologists to study the functions of different areas of the brain. Some of them are very old methods and outdated; some of them are most recent in origin and frequently used by modern investigators. The methods help us to study the localization of the functional areas of the brain. One of these methods is the stimulation method. A specific part of the brain may be stimulated either by electric current or by chemicals. Through electrical stimulation, we can only stimulate the desired part of the brain. But by chemical methods, we can stimulate or defunct a particular part of the brain for a fixed period of time and observe their effects on behavior. Another method is the Electrical Recording or Action Potential Method.The rhythmical electrical discharges of the brain are recorded by an instrument called electroencephalogram (EEG). The EEG can detect minute electrical activities of the brain cells during sleep, arousal and activity. The brain parts having greatest electrical activity can be linked with behaviors and sensations of the body. This will tell how the body surfaces are represented in the brain. The Computerized Axial Tomography (CAT) is a newer method in which thousands of separate X-rays are taken at slightly different angles, and the computer constructs an image of the structures of the brain by combining these X-rays. It is very useful for showing abnormalities in the structure of the brain such as swelling and enlargement of certain parts. But it does not provide information about brain activity. Another method is Magnetic Resonance Imaging (MRI). It produces a strong magnetic field in which the persons head is positioned. The radio waves directed at the brain cause the hydrogen atoms to emit signals, which are analyzed by a computer. The details of the MRI are superior to CAT scan, because it can distinguish between closely related brain structures. Due to its importance, you might think the brain would be a little more forthcoming about its design and function. Fortunately, the human brain also provides us with the remarkable ability and ingenuity to study the human brain, a skill in which brains of other life forms decidedly come up short. The study of the brain has yielded remarkable findings, and advances in brain research have created a better understanding of the way we function and life itself.

Does Competition Bring Out The Best In Us? :: essays research papers

COMPETITION BRINGS OUT THE BEST IN US The score was 14-15. My team was losing the sectional championship game by just one point. Now we had to give our all to win, or we would be regretting the loss for years to come. In order to win, we had to get along with everyone on, and off, the volleyball court. We had to believe in ourselves, but most of all, we had to use all of the competitive skills that we had learned throughout our lives from parents, coaches, and our own experiences. Each second, the game became more and more intense. After playing our hearts out for two rotations, the score was now in our favor. We were winning 16-15. As soon as we were in control of the game, we competed at a collegiate level that no one would have thought was possible. Our skills were equal to the skills of a college player. The hitters could jump so high that their entire arm was swinging above the net. The blockers all had at least half of their arm making a wall over the net. The defensive players all dug up balls that looked like comets beaming onto the court. We were just twelve girls on a high school team, but the skill and talent we were showing to win against our rival could have been even better than a professional team. We ended up being the team that was celebrating victory in the locker room. We all had our chance to yell, cheer, and jump up and down after we shook our opponents hands. We finally had the opportunity to celebrate an amazing victory. We were even int erviewed by reporters and photographed by staff of the Hearld Argus, our city’s paper. Competition brought out the best in each one of us that night and that season. The skills we learned and showed on the court will never be forgotten. We learned to get along as a team, believe in ourselves, and to never give up on a goal. In order to succeed, people must compete. Competition can bring out the best in everyone. During a single day, people in some way compete with themselves or with others. They compete to win a sporting event, to get a raise or promotion in their workplace, to receive the best grades on tests or homework assignments, and to be the best at everything they do.
