Which brain region is primarily associated with higher cognitive functions such as reasoning and planning?

• A. Cerebellum
• B. Brainstem
• C. Medulla Oblongata
• D. Cerebrum

Answer: (D)

Higher cognitive functions such as reasoning and planning are carried out mainly by the cerebrum, which houses the cerebral cortex. The frontal lobe, part of the cerebrum, is especially important for executive functions like planning, problem solving, and decision making. The cerebellum is primarily involved in coordinating movement and motor learning, not the core processes of reasoning. The brainstem, including the medulla oblongata, regulates basic life-sustaining functions such as breathing and heart rate and serves as a major relay for neural signals. Therefore, the cerebrum is the region most closely associated with higher cognitive functions.
