Welcome to the Huberman Lab Podcast, where we discuss science and science-based tools for everyday life. I'm Andrew Huberman and I'm a professor of neurobiology and ophthalmology at Stanford School of Medicine. Today we are discussing the vagus nerve. The vagus nerve, or what neuroanatomists call cranial nerve 10, is an extremely interesting nerve because when we hear the word nerve, We often think of a small, you know, connection between one thing and another, the wires of the nerve, which of course we call axons.

If you didn't know that, now you know they're called axons. But actually the cranial nerve is an extensive pathway. It's a whole set of connections that link the brain and body. In fact, in many respects, it looks kind of like its own nervous system. within the traditional nervous system of the brain and the spinal cord, the connections between spinal cord and muscle.

The vagus nerve is so vast, it spreads out through so much of the body and as you'll learn today, it's connected to so many interesting different brain areas and has so many interesting different functions that it deserves, well, an entire episode of this podcast. The other great thing about the vagus nerve is it is highly actionable, meaning what you will learn today If you already know something about the vagus nerve, is going to change what you know and believe about the vagus nerve. What you hear today will also, if you don't know or you're not familiar with the vagus nerve, is going to educate you on the latest about the vagus nerve. We've learned a lot about the vagus nerve and ways to control the vagus nerve in the last few years.
