Answer to Question 1

Answer: 1, 2, 4
Explanation: Recent research focuses on the prefrontal area, the limbic system, and the basal ganglia. The limbic system is the area most responsible for mood and emotion and contains the hippocampus, cingulated gyrus, septum, and amygdala. The basal ganglia are important in the role of cognition, reward, and mood regulation. The prefrontal area is essential to the creation and expression of emotion.

Answer to Question 2

Answer: 2
Explanation: The diathesis-stress model states that certain individuals inherit tendencies to express certain traits or behaviors when exposed to the right conditions or stressors. A patient's diathesis, or hereditary predisposition, must interact with life events in order to trigger depression. A life trauma, especially during the formative years of childhood, may predispose vulnerable individuals to alteration in brain neurochemistry that initiates the process for future mood disorders.
