Theories Broca & Wearnikle Brocas aria is located in the frontal lobe on the left hemisphere. It is thought that it controls and coordinates the muscles we need to use in order to speak. It is also suggested that its involved in analyzing the grammatical structure of a sentence in order to extract its meaning. Wernikles aria is located in the temporal lobe on the left hemisphere. Its task theoretically is to help with the understanding of speech. Its also seems to play a part in our selection of appropriate words from our vocabulary. Both these theories are based on observations of subjects whove suffered some form of brain damage in that aria. Damage to these arias shows crippling effect on speech (Broca) and comprehension of speech (Wernikle) Both are very important because they each play a major role in the way we communicate. Method Ask subject to stare at a dot in the center of a screen. - Flash an image of a common object on left side of the screen (outside the right visual field) - Ask subject to identify the common object. Results When the image is flashed in the right visual field the subject recodnizes and verbally identifies the image. When it is flashed on the left side the subject still recodnises the image but cannot verbally express what it is. This is because while both hemispheres are capable of recodnizing the object only the left hemisphere can convert the information into spoken word. So when the subject sees the image with his/her left eye the information goes into the right hemisphere were it is recodnised. Then it attempts to cross to the right hemisphere to Brocas aria so we can SAY what it is it finds that there is no bridge (Corpus Collosum) for it to get across by.
