The olfactory system can have direct effects on energy homeostasis The sense of smell, or olfaction, allows animals to survey the chemical landscape of the outside world and use this information to guide behavior. Olfactory cues are particularly important for the regulation of feeding, but how odor perception influences other aspects of energy homeostasis remains poorly understood. Recent work has begun to uncover some of these connections, revealing an unexpected role for olfaction in the control of metabolism and longevity.

将气味与新陈代谢和衰老联系起来

嗅觉系统可以对能量稳态产生直接影响嗅觉或嗅觉使动物能够调查外部世界的化学景观并使用这些信息来指导行为。嗅觉线索对于调节进食特别重要，但气味感知如何影响能量稳态的其他方面仍然知之甚少。最近的工作已经开始揭示其中的一些联系，揭示了嗅觉在控制新陈代谢和长寿方面的意想不到的作用。
