In addition to regulating the ingestion and digestion of food, sensory feedback from gut to brain modifies emotional state and motivated behavior by subconsciously shaping cognitive and affective responses to events that bias behavioral choice. This focused review highlights evidence that gut-derived signals impact motivated behavior by engaging vagal afferents and central neural circuits that generally serve to limit or terminate goal-directed approach behaviors, and to initiate or maintain behavioral avoidance.
除了调节食物的摄入和消化,肠道向大脑传递的感觉反馈通过潜意识地塑造对事件的认知和情感反应,从而改变情绪状态和动机行为,影响行为选择。本综述重点强调了肠道来源的信号通过激活迷走神经传入和中枢神经回路来影响动机行为的证据,这些信号通常用于限制或终止目标导向的趋近行为,并启动或维持行为回避。
