Left And Right Brain Essays - Cerebrum, Neuroscience,

Left and Right Brain The article in which I chose to examine is called Right Brain, Left Brain: Fact and Fiction, written by Jerre Levy. In the past fifteen years or so there has been a lot of talk of left brain and right brain people. Levy's reason for righting this article was clearly to stop the misconceptions and show the truth about how our brain hemispheres operate. Levy first explores the myth of the left brain and right brain theory. She states that generally people see the left hemisphere of the brain controlling logic and language and the right, creativity and intuition. In addition people differ in their styles of thought, depending on which half of the brain is dominant. She believes that most of what these notions state is farce. Next the article explores the history of this fascination of the left and right hemispheres of the brain. Apparently the study of this aspect of the brain traces back to time of Hippocrates. Levy weaves in and out of the various theories and prominent people known f or contributing to the confusion. It wasn't until 1962 when Roger W. Sperry began experimenting on certain aspects of the brain that contribute to the truth of the left and right brain theory. Sperry studied people who had undergone surgical division of the corpus callosum, the bridge between the two hemispheres. His studies showed that, "an object placed in the right hand (left hemisphere) could be named readily, but one placed in the left hand (nonverbal right hemisphere) could be neither named nor described. Next to branch off of Sperry's studies was psychologist Doreen Kimura. Kimura developed behavioral methods which involved presenting visual stimuli rapidly to either the left or right visual fields. Another important method developed was "dichotic listening" which centered around the use of sound to study the hemispheres. Through these tests and the continual study the theory that the left brain controlled ended. Instead a new theory was born known as the two-brain theory. Th is said that at different times one of the two hemispheres would be operating. An example of this is that the right hemisphere is in control when an artist paints but the left hemisphere was in control when a novelist wrote a book. This theory failed because of one physical studies showed that people with hemispheres surgically disconnected could operate in everyday life. Also, research demonstrated that each hemisphere had its own functional expertise, and that the two halves were complementary. Next, the article states its worth. The author shows the up to date agreed upon theory of the two hemispheres in five simple points. 1. The two hemispheres are so similar that when they are disconnected by split-brain surgery, each can function remarkably well, although quite imperfectly 2. Although they are remarkably similar they are also different. The differences are seen in contrasting contributions. Each hemisphere contributes something to every action a person takes. 3. Logic is not confined to the left hemisphere. Although dominant in the left logic is present in the right hemisphere. 4. There is no evidence that either creativity or intuition is an exclusive property of the right hemisphere. Same theory as #3. 5. Since the two hemispheres do not function independently, and since each hemisphere contributes its special capacities to all cognitive activities, it is quite impossible to educate one hemisphere at a time in a normal brain. Levy comes to the conclusion that people are not purely left or right brained. There is a continuum in which the hemispheres work together in harmony. Often the left or right hemisphere is more active in some people but it is never the sole operator. She concludes, "We have a single brain that generates a single mental self." Compared to what we did in class related to the left and right hemispheres of the brain, both what we learned and the article taught were extremely similar. Our exercise showed that we are not left or right brained but merely somewhere on the scale between left and right brain. Some of us were extreme left, few extreme right and most in the middle leaning left a bit (this is where I fell). I could
