what problem does damage to broca area cause?
aphasia
since studies carried out in the late 1970's it has been understood that the relationship between broca's area and broca's aphasia is not as consistent as once thought. lesions to broca's area alone don't result in a broca's aphasia, nor do broca's aphasic patients necessarily have lesions in broca's area. lesions to broca's area alone are known to produce just a transient mutism that resolves inside 3–6 weeks. this discovery suggests that broca's area may be included in some aspect of verbalization or articulation; however, it does not address its part in sentence comprehension. still, broca's area frequently emerges in functional imaging studies of sentence processing. however, it also becomes activated in word-level tasks. this suggests that broca’s area is not dedicated to sentence processing but supports a function common to both. in fact, broca's area can show activation in such non-linguistic tasks as imagery of motion.
