A decision to eat or not to eat can be beneficial or detrimental to an organism, depending on internal and external conditions. Because feeding is essential for survival, as it replenishes energy and nutrients, in safe environments, its expression is prioritized over other behaviors. Under threat, responding to danger is a higher priority for survival and feeding is paused even in hungry states. Thus, successful expression of feeding behavior requires adaptive control that utilizes cognitive processes to dynamically assess and update internal drives and environmental changes. Recently identified key circuit components, which are important in anticipatory responding based on food memories and predictions and in resolving feeding versus threat avoidance competition, will be discussed within a connectional schema.
进食或不进食的决定对生物体可能有益也可能有害,这取决于内部和外部条件。由于进食对生存至关重要,因为它能补充能量和营养,在安全的环境中,其表现比其他行为更受优先考虑。在受到威胁时,对危险做出反应对生存来说是更高的优先事项,即使处于饥饿状态,进食也会暂停。因此,进食行为的成功表现需要适应性控制,这种控制利用认知过程来动态评估和更新内部驱动力以及环境变化。本文将在一个连接模式中讨论最近确定的关键神经回路组件,这些组件在基于食物记忆和预测的预期反应以及解决进食与避免威胁的竞争中很重要。
