What is Which structure connects the Broca's and Wernicke area? and explain in detail?
Arcuate fasciculus connects Wernicke's area present in posterior superior temporal gyrus of dominant hemisphere (sensory area of speech) to broca's speech area present in prefrontal & premotor facial region of cerebral coex to integrate language understanding & skilled motor function. Damage to Wernicke's area = Wernicke's aphasia (lack meaning) Damage to Broca's area = motor aphasia (vocal system couldn't emit words) Damage to arcuate fasciculus = conduction aphasia
