At a Loss for WordsI did not feel uniform A.H. Raskin. I now had a new self, a somebody who no longer could use words with mastery. A.H. Raskin, editor for the NY TimesLanguage is the principal mode whereby we formulate our thoughts and convey them to others. It allows us to disclose our fondest memories of the past and communicate our emotions. Language has been instilled in us ever since we were babies inside our mothers womb. We often start language for granted since around of us keep never had to live a life of silence. It is perhaps because of this that people who have suffered brain damage caused by strokes, gunshot wounds, brain tumors, or other traumatic brain injuries feel a loss of self when they lose their ability to speak (1) . If we cant talk then we cant communicate right? Wrong. We often speak of our brains being lateralized. What is brain lateralization exactly? Brain lateralization pertains to the point that the two halves of our so-called symmetrical brain are not exactly alike. There are functional specializations that are specific to each hemisphere (2). For the most part language areas are concentrated in the left hemisphere. Surprisingly, only about three percent of right-handers and nineteen percent of left-handers have language controlled by the right hemisphere (3). Two major areas of the brain, Brocas area and Wernickes area are responsible for language production and language comprehension, respectively. It is fairly severe to assess exactly what parts of the brain control language, anything really, by any means other than clinical reports of people with brain injuries or diseases. Approximately wiz million people in the United States currently have aphasia, the language disorder that results from damage to portions of the brain responsible for language (1). Some people with aphasia have problems primarily with expressive language often termed Brocas aphasia, whereas others have problems with receptive language often dubbed Wer nickes aphasia (3). The two get their names from Paul Broca, a French neurosurgeon, and Carl Wernicke, a German neurologist who identified their respective parts in the mid-1800s (2). Brocas area describes the lower rear portion of the frontal lobe on the left side that is in front of the motor strip (4). Patients with Brocas aphasia often omit small words such as is, and, and the (5). A person with this type of aphasia may say, Walk dog meaning, I will take the dog for a walk.
