Which brain region forms the outer layer of the brain responsible for higher cognitive functions?

• A. Cerebral Cortex
• B. Cerebellum
• C. Brain Stem
• D. Hypothalamus

Answer: (A)

The cerebral cortex forms the outer layer of the brain and is the seat of higher cognitive functions such as thinking, planning, language, perception, and problem solving. It’s a highly folded sheet of neural tissue that increases surface area, allowing many neurons to participate in complex processing. The other regions have different roles: the cerebellum coordinates movement and balance; the brain stem controls basic life-sustaining functions like breathing and heart rate; the hypothalamus regulates drives and homeostasis (hunger, temperature, hormones). So, the outer layer responsible for advanced cognitive processing is the cerebral cortex.
