What is Which structure connects the Broca's area 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 of Broca's area => motor aphasia (vocal system couldn't emit words) Damage of Arcuate fasciculus => conduction aphasia - Anterior commissure => white mattes tracts that connects two temporal lobes of cerebral hemispheres across midline (especially amygdala) - Corpus callosum: band of nerve fibers providing bidirectional neural connections b/w most of coical areas of two cerebral hemispheres (except anterior poions of temporal lobes - Fornix - 'c' - shaped bundle of nerve fibers in brain acting as major output tract for hippocampus
