Appropriate reaction to changes in the environment is essential for survival. Appetitive stimuli decrease anxiety levels and activity of the stress-related hypothalamic-pituitary adrenal (HPA) axis in order to promote seeking and consumption of food. Conversely, imminent danger activates the HPA axis and suppresses feeding and other behaviors non-related to immediate fight or flight reaction. This coordination of specialized physiological systems requires precise functioning of interfaces between specific neuronal networks involved in stress and feeding behaviors.

对环境变化的适当反应是生存所必需的。食欲刺激会降低焦虑水平和压力相关的下丘脑-垂体肾上腺(HPA)轴的活动，从而促进对食物的寻找和消费。相反，迫在眉睫的危险会激活HPA轴，抑制进食和其他与即时战斗或逃跑反应无关的行为。这种特殊生理系统的协调需要参与应激和摄食行为的特定神经网络之间的精确接口功能。
