Does The Wernicke Use Sign Language

I have picked the Wernicke's area. The Wernicke's area is a region of the brain that is concerned with the comprehension of language. The Wernicke's area is located in the cortex of the dominant temporal lobe.It is found on the posterior third of the upper temporal convolution of the left side of the temporal lobe.Right handed people have it in this location practically ninety percent of the time. This same area of the brain is found in deaf people, who also use sign language. The Wernicke's area is essential to understanding the relationships between words and their meanings.This last finding, hints that Wernicke's area may not be used for spoken language.The Wernicke's area is connected by a bundle of nerve fibers called the arcuate fasciculus,
