Why Listen to This Episode? 


In this first of a two-part series, I sit down with Dr. Kevin J. Tracey, neurosurgeon, CEO of the Feinstein Institutes for Medical Research, and founder of the field of bioelectronic medicine. He’s also one of the most widely cited medical experts in the world. Together, we explore the science behind the vagus nerve, a vast communication highway between your brain and body that is proving to be a powerful regulator of inflammation. 


Just weeks ago, the FDA approved the first implantable vagus nerve device for rheumatoid arthritis, a breakthrough that could pave the way for treating other conditions without drugs. Dr. Tracey explains what this milestone means, how the device works, and why it could someday replace some of the medications people rely on for chronic disease management. 


What You’ll Learn in Part 1 



  • What the vagus nerve is, where it’s located, and why it matters. 

  • How inflammation drives diseases like heart disease, Alzheimer’s, arthritis, and more. 

  • The story behind the FDA-approved device that may change how we treat rheumatoid arthritis. 

  • Why bioelectronic medicine could represent a seismic shift in healthcare.
