In the middle of these two hemispheres is a bundle of nerve fibers. This bundle, called the corpus callosum, is a network of circuitry allowing the left and right hemispheres to communicate -- but when someone has a disability, it often becomes more of a wall.
If someone has dyslexia, for example, visual information taken in bounces off of the wall and comes out differently, perhaps backwards or upside down. Some people similarly recieve auditory information that bounces off the wall and gets lost. In that case, they have a difficult time concentrating, holding on to what is heard, and tuning out extraneous information. These students can’t always comprehend directions in auditory memory, either, and may only hear bits and pieces of words and sentences. This also causes issues with isolation, since people build relationships through verbal communication.
