The Broca area : processes information it receives from the area of \u200b\u200bWernicke for vocalization patterns. When a word is heard , the feeling is received at the hearing by the primary auditory cortex, but the word can not be understood until the signal has been processed in the area of \u200b\u200bWernicke. If the word is to be vocalized, the signals go through the booklet arched to Broca's area. In Broca's area evokes a detailed joint program supported by the motor cortex and muscles of the face and mouth (effectors).
When a word is read , the sensation is registered by the primary visual cortex, then the signal passes through the angular gyrus which visually associates the word with the corresponding auditory pattern in Wernicke's area. then goes through and reaches the arcuate fasciculus to Broca's area. Expressive Aphasia
: If the damaged area is the area of \u200b\u200bBroca, the patient speaks slowly and has difficulty expressing words. Receptive aphasia
: If the damaged area is the area of \u200b\u200bWernicke, the subject is fluent, but uses the wrong words, does not receive its own language. Conductive Aphasia
: If the damage is in the arcuate fasciculus, the patient understands what he hears and speaks fluently but can not repeat the words. Nominal Aphasia
: If the damage is at the junction of temporal and occipital lobes, the patient has difficulty naming objects, colors and other elements known.
