What is Dyslexia? Dyslexia is a common neurological lifelong condition which affects 1 out of 5 people in the country (Facts About Dyslexia, 2008). It is not caused by poor vision(Understanding Dyslexia, 2014); in fact it can happen to those whom are very intelligent (Davis, 1992). The brain has difficulty processing reading, written and spoken language (Facts About Dyslexia, 2008). People with dyslexia need a little more time and a different way to process the information (Understanding Dyslexia, 2014). What part of the brain is affected? Individuals with dyslexia actually process information in a different part of the brain; the right of their brains understand language called the planum temporale but they often cannot…show more content…
In a study it was discovered a structural difference in two parts of brain, in the cerebral cortex and thalamus. The cerebral cortex it is a six layer in the outer part of the brain which processes sensory, motor, memory, language, and attention. The thalamus is located in the center of the brain it processes information from the eyes and ears (Neuroscience, 2000). There are nerve cells and nerve fibers located in the first layer of the cortical area which is responsible for language called ectopias; Ectopias sometimes travel too far and end up in foreign places. Scientists believe that this occurs during the development of the brain of a fetus before its sixth month (Structrual Brain, 1999). Ectopic neurons connect to other parts of the brain differently; Most ectopias are in the language area, and the front part of the brain is related to verbal memory (Structrual Brain, 1999).. With different wiring patterns in the brain it affects the reading and writing process (Structrual Brain, 1999). To say a word that is read, the information goes to the primary visual cortex; the word then goes to the primary visual cortex which then travels to the posterior speech area, including Wernicke’s area and to Broca’s area, and lastly to the
