What are two examples of localisation of function and their corresponding brain areas?

• A. Broca's area for speech production and Wernicke's area for language comprehension
• B. Amygdala for balance and Hippocampus for vision
• C. Motor cortex for smell and Visual cortex for hearing
• D. Prefrontal cortex for digestion and Cerebellum for emotion

Answer: (A)

Localization of function is the idea that specific brain areas are responsible for particular mental processes. Two classic examples illustrate this: Broca's area in the left frontal lobe is involved in speech production, while Wernicke's area in the left temporal lobe is involved in language comprehension. This demonstrates a division of labor in the brain for language: damage to Broca's area leads to difficulty producing fluent speech, whereas damage to Wernicke's area impairs understanding and can produce fluent but meaningless speech. The other options mix up functions with brain regions—amygdala is more about emotion, not balance; the hippocampus is tied to memory, not vision; the motor cortex is not for smell, and the visual cortex is not for hearing; the prefrontal cortex and cerebellum are not responsible for digestion or emotion in the way described.
