What functional brain area is involved in language comprehension and is typically located in the left superior temporal gyrus?

• A. Broca's area
• B. Wernicke's area
• C. Inferior parietal lobule
• D. Temporal pole

Answer: (B)

Language comprehension hinges on a specialized left-hemisphere region that interprets spoken language by turning sounds into meaning. This region sits in the posterior part of the left superior temporal gyrus and is classically known as Wernicke's area. It integrates auditory input with semantic knowledge to understand words and sentences. When this area is damaged, speech can be fluent and well-formed but may lack meaning, showing a deficit in comprehension. Broca's area, by contrast, is in the left inferior frontal gyrus and is primarily involved in speech production and grammar. The inferior parietal lobule participates in integrating language with other modalities and in reading and calculation, rather than being the core site for understanding spoken language. The temporal pole contributes to broader semantic processing, but the key region for language comprehension specifically is Wernicke's area.
