Sign Language in the Brain

Introduction

It is very difficult to analyze a human brain. How it senses and interprets the language. In this paper we will discuss about the processes of producing languages and signs by the brain. Overall structure of brain is sensible to make sure all the possible functions in different regions are working properly. (Clark, 2003) The brain of human is composed of different parts that operate certain functions of the body. Certainly, few particular parts of the brain control the production of languages. However, this study would not focus on how brain produces languages but what are the factors that bar in the language production process. In this connection this study would attempt to answer following questions.

In what ways are signed and spoken languages represented similarly or differently in the brain?

What are some of the effects of right-hemisphere damage on sign use?

Discussion

There is a strong relationship between brains and producing of language, however, often injuries to the parts of brain which produces languages may cause certain irregularities in language. Number of studies is available which attempts to define the causes of difficulty people often experience in communicating due to damage parts of the brain which performs this function. The possible barrier in producing the language depends on which part of the brain is damaged. For instance a damaged front left side of the brain may not be able to speak properly. However, other people, and destroyed the back right hand side of the brain, might be able to produce a well structured language, discourse, but may have lost the ability of some space, but cannot see more than one thing at a time. Since the mid 19th century, especially between brain regions and their functional relationship may have been inferred from the individual systems such as brain injury models are described. This research has provided the basis for follow-up studies have established the basic map of the brain.

French Neurologist suggests that people who had difficulty in speaking the language has damaged brain's left hemisphere known as Broca's area. Similar study by Carl Wernicke found that people with problems in comprehension has another part of left hemisphere, damaged which was dubbed as Wernicke's area. However, Aphasias or the right hemisphere have always been considered only a minor factor which causes such disruption. The right hemisphere results in visual spatial problems. In this connection the left hemisphere is called verbal hemisphere, and right hemisphere is called spatial hemisphere. In this connection a study Hickok, Bellugi and Kilma in (2001) presented a study which discusses the question that "is brain's organization for language truly based on the functions of hearing and speaking." The study examines different deaf signers who have damage left or right hemisphere, in order to examine their ability to understand and produce sign languages. This will help in the study to determine the brain region that generates and interpret sign languages and will compare it, ...
