Answer to Question 1

The prefrontal cortex is in the frontal lobe. It regulates cognitive processes such as planning and problem-solving and functions as the center for postponing gratification, self-discipline, and emotional regulation. Because this is the last part of the brain to mature fully, stress may have a greater impact on the prefrontal cortex of those under age 25. At any age, stress affects both the structure and function of the prefrontal cortex by causing neurons to atrophy and by disconnecting circuits.
