The Effects Of Magnetic Resonance Imaging On The Brain

Decent Essays
In the last 15 years neuroscientists have learned a lot about the brain and its complexities. The brain as we know it can be categorized into two parts, lower levels like the brainstem, and higher levels like the cerebral cortex. The cortex has two hemispheres with four lobes, the occipital, parietal, temporal, and frontal lobes. However, many people still believe that the left hemisphere and the right hemisphere are separated for functions such as logicality and creativity. However, this is a misunderstanding from a previous study when the brain was damaged, but now our methods have improved. Magnetic Resonance Imaging (MRI) is an example, the machine can help doctors see inside the brain, and have even helped scientists realized that

    Jill Bolte Taylor’s bestseller, My Stroke of Insight, is a polished literary work that can be easily read by a large audience. You don’t need to have the knowledge of a brain scientist to follow along; in fact, the second and third chapter has a summarized introduction to simple science of our bodies and our brain including hemispheric asymmetries. Readers are able to flow through Taylor’s exploration of new sensations from heavy reliance on her right hemisphere. This amalgamation of all little details of Jill’s life pre-stroke all the way through her eight year in recovery In 1996 and at age 37, Taylor had a severe hemorrhage in the left hemisphere that had debilitating effects on her perception, movement, coordination, thought processes…

    Broca's Act Summary

    At a first glance, hemispheres look like mirror images (identical). However, science has been proving since 1968 effectively through examinations of positron emission tomography (PET), functional magnetic resonance imaging (fMRI), electroencephalography (EEG) and regional cerebral blood flow (rCBF), the existence of anatomical asymmetries, neurochemical and functional, thereby designating the hemispheric specializations. Paul Broca (1860), through work and biopsies found that the language processing was given in the left hemisphere. Broca also addressed the relationship between the use of the hand and speech, and attributed the innate superiority of the left hemisphere in right-handed. Created then, the "Broca’s Act", that the speech controller hemisphere is opposite to the dominant hand.…

    The development of the MRI (Magnetic Resonance Image) machine has changed the medical world for the better. One of the first points about the MRI is that it was created by Professor Raymond Damadian in 1977. The first time the MRI machine was used, it took a total of five hours to do the whole scan. Also, the first MRI machine ever used is now in the Smithsonian Institute, and was nicknamed the “Indomitable.” Many people think they know what an MRI machine does, but most of the time they are wrong.…

    Analyzing “Brainology” In the following essay, we will analyze and discuss the article “Brainology” by Carol Dweck. Starting off by the title, the opening paragraphs, the claim, the author’s purpose, methods, persona and closing paragraphs as well. Because I believe Dweck’s article was more effective than ineffective, reasons of why I believe she could've done a better work will be discussed and explained in short. The title the author chooses for this article, “ Brainology”, introduces the audience to what she will be talking about, it is important to point out that the word “brainology’ induces us to think of a very broad topic which could be understood as a study of the brain.…

    They can study how it works, what parts are linked to different issues and different problems. Magnetic resonance imaging (MRI) as an advanced technology allowed us very carefully to control the experiment with live participants in non-invasive way. Numerous images of brain offers opportunity to look at fine details at the deeper structure of the brain without surgical intervention. While MRI is all about the structure of the brain another modern technics are known as functional brain imaging (fMRI) which investigates the activity of the brain.…

    Analysis of “My Stroke of Insight” The Ted talk “My Stroke of Insight” given by a Neuroanatomist, Jill Bolte Taylor, is about how humans have a left hemisphere and a right hemisphere and how humans have different perceptions of themselves because of it. In the right hemisphere people tend to think that they are “energy-beings connected to one another through the consciousness of our right hemispheres as one human family.” People who tend to think with their left hemisphere are responsible for thinking of themselves as single individuals. In this talk she asks us an important question, “which side do you choose and when?”…

    However there were criticisms and perhaps the main one was how the information gained from the studies by Sperry and Gazzaniga was interpreted by our culture and the media. It led to the mistaken beliefs that we either have half a brain or two distinct brains which are both wrong. I find it fascinating to learn that when reading a book the left hemisphere understands the actual words and the right helps us to imagine what is happening in the story. I believe that Sperry and Gazzaniga conducted these experiements and studies in order to increase our understanding of the functions of the brain so that victims of head trauma such as a stroke can recieve better care and treatment because we will better understand which area of the brain is damaged and how to repair it. The article is extremely interesting to me because i now know that when i walk into my kitchen and i see a microwave, the right hemisphere allows me to say "that is my microwave".…

    At the age of two years old, the brain of a child has almost developed the same as the adult size while other parts of the child still have not grown as speedily as the brain. The growth of the brain extend the cognitive skills and motor skills (Pg 215). In the brain, there are two hemispheres; left and right. The right hemisphere controls the creative side while the left brain controls logical tasks. Surprisingly, there is a difference in lateralization for boys and girls. "…
