How Smell, Taste & Pheromone-Like Chemicals Control You | Huberman Lab Podcast #25
发布时间 2021-06-21 12:00:19 来源
摘要
This episode I explain how we sense chemicals by way of smell, taste and pheromones. How things smell and taste and bodily chemicals of others have a profound effect on how we feel, what we do and our hormones. I explain the 3 types of responses to smell, the 5 types of tastes, the possible existence of sixth taste sense. I explain how smell and taste reflect brain health and can be used to assess and even promote brain regeneration. Both basic science and protocols are described including how to make sour things taste sweet and how to develop a heightened sense of smell and taste.
