The Huberman Lab Podcast discusses neuroscience: how our brain and its connections with the organs of our body control our perceptions, our behaviors, and our health. We also discuss existing and emerging tools for measuring and changing how our nervous system works. Dr. Andrew Huberman is a tenured Professor of Neurobiology and Ophthalmology at Stanford School of Medicine. His laboratory studies neural regeneration, neuroplasticity, and brain states such as stress, focus, fear, and optimal performance. For more than 20 years, Dr. Huberman has consistently published original research findings and review articles in top-level peer-reviewed journals, including Nature, Science, Cell, Neuron, and Current Biology. He is a regular member of several National Institutes of Health review panels and a Fellow of the McKnight Foundation and the Pew Charitable Trusts. Dr. Huberman regularly consults for technology development companies, professional athletic organizations, and various units of U.S. and Canadian Special Operations.

How Smell, Taste & Pheromone-Like Chemicals Control You | Episode 25

This episode explains how we sense chemicals through smell, taste, and pheromones. How things smell and taste and chemicals in the tears, breath, and on the skin 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, and how the act of sniffing can make us learn and focus better. I explain how smell and taste reflect brain health and can assess and even promote brain regeneration. I discuss how eating specific categories of foods makes us crave more of those foods, including how to make sour things taste sweet and develop a heightened sense of smell and taste.
