Our language abilities result from intricate coordination of many brain areas. Learning more about the function of each of these areas allows physicians to find the root of language impairments. Aphasia is the impaired use of language but not necessarily all aspects of it.
Norman Gershwind, an American behavioural neurologist, noted the order and way in which we interpret language. First we hear or read language, which is received by the visual cortex as written words. These written words serve as visual stimulation. Then, the angular gyrus transforms the visual stimulation into an auditory code. Next, Wernicke’s area interprets the auditory code. Broca’s area, controlling our speech muscles via the motor cortex enables us to reply based on the interpreted information.
