Which brain region is primarily linked to language comprehension?

• A. Broca's area
• B. Wernicke's area
• C. Arcuate fasciculus
• D. Prefrontal cortex

Answer: (B)

Understanding spoken language relies on receptive language areas, especially in the left hemisphere. Wernicke's area, located in the left temporal lobe, is specialized for processing the meaning of language and understanding speech. When this region is damaged, people often speak fluently but with little meaningful content and have trouble understanding what is being said, a pattern known as Wernicke's aphasia. Broca's area, by contrast, sits in the left frontal lobe and governs language production and grammar, so damage here hurts speaking and forming sentences rather than understanding. The arcuate fasciculus is a white-matter tract that connects Wernicke's and Broca's areas; damage can disrupt repeating heard speech, but it is not the primary site for understanding language. The prefrontal cortex handles planning, decision making, and working memory, not language comprehension per se. So, the region most closely linked to language comprehension is Wernicke's area.
