The prefrontal cortex is part of which brain region responsible for thinking, planning, and language?

• A. Prefrontal cortex
• B. Occipital lobe
• C. Temporal lobe
• D. Parietal lobe

Answer: (A)

Think of thinking, planning, and aspects of language as functions of the frontal region of the brain. The frontal lobe sits at the front of the brain, and its executive center—the prefrontal cortex—guides higher-order processes like planning, goal-directed behavior, working memory, and decision-making. It also supports language production in coordination with other language areas that reside in the frontal and temporal lobes. The other lobes have different primary roles: the occipital lobe handles vision, the temporal lobe processes auditory information and memory (and language comprehension to some extent), and the parietal lobe integrates sensory information and spatial reasoning. So, the region responsible for these complex thinking and language functions is the frontal lobe, with the prefrontal cortex as a key part within it.
