Final answer:
Broca's and Wernicke's areas are in the left hemisphere, with Broca's in the frontal lobe, essential for speech production, and Wernicke's in the temporal lobe, essential for language comprehension.
Step-by-step explanation:
Broca's and Wernicke's areas are key regions in the brain associated with language functioning. They are located in the left hemisphere for roughly 95% of the population. Specifically, Broca's area, crucial for language production, is found in the frontal lobe, while Wernicke's area, essential for language comprehension, is situated in the temporal lobe near the auditory cortex.
Both regions are interconnected and their coordination is vital for normal linguistic abilities.
