In which area of the brain is the speech area predominantly located in right-handed individuals?

The speech area in right-handed individuals is predominantly located in the temporal lobe, specifically in an area known as Wernicke's area. This part of the brain is critical for language comprehension. Right-handed individuals typically have a more specialized use of the left hemisphere for language processing, where Wernicke's area resides. It plays a crucial role in the ability to understand and produce spoken and written language.

While the frontal lobe is involved in speech production due to Broca's area, which is also located in the left hemisphere for most right-handed individuals, the comprehension aspect of speech is more specifically associated with the temporal lobe. The parietal lobe and occipital lobe do not primarily handle language functions, making the temporal lobe the correct answer in the context of speech comprehension.
