How does your brain process language?

Discovery Channel
Processing language requires two different sections of your brain. Wernicke's area, located in the rear of the parietal lobe, controls your ability to process sounds associated with language. If this area is damaged, you cannot understand language, even though you can still make sounds; this is called sensory aphasia. Broca's area, on the left side of your frontal lobe, manages your ability to make sounds. If this area of your brain is damaged, you can understand language but can't produce coherent sounds yourself; this condition is called motor aphasia.
