Which of the following processes is NOT a function of the cerebral cortex?

• A. Language processing
• B. Sensory perception
• C. Regulation of breathing and heart rate
• D. Voluntary motor control

Answer: (C)

Verified step by step guidance

1. Step 1: Understand the role of the cerebral cortex. The cerebral cortex is the outer layer of the brain involved in higher-order brain functions such as sensory perception, voluntary motor control, language processing, and complex cognitive tasks.
2. Step 2: Identify the functions listed in the problem: language processing, sensory perception, regulation of breathing and heart rate, and voluntary motor control.
3. Step 3: Recall that regulation of breathing and heart rate is primarily controlled by the brainstem, not the cerebral cortex. The brainstem manages autonomic functions necessary for survival.
4. Step 4: Compare each function to the known roles of the cerebral cortex. Language processing, sensory perception, and voluntary motor control are all functions of the cerebral cortex.
5. Step 5: Conclude that the process NOT a function of the cerebral cortex is the regulation of breathing and heart rate, as it is controlled by lower brain structures like the brainstem.
