Welcome back to Ditch the Lab Coat, the podcast where we break down the fascinating world of medicine with a blend of scientific skepticism and real-world insight. In today’s episode, we dive deep into the mysteries of the vagus nerve—a nerve so ancient and essential, it’s been called the “conductor” in the symphony of human physiology.
Join host Dr. Mark Bonta as he sits down with Dr. Kevin Tracey, neurosurgeon, president and CEO of the Feinstein Institutes for Medical Research, and a pioneer in the world of bioelectronic medicine. Dr. Tracey’s breakthrough research has shown us that the vagus nerve is far more than just a conduit for signals—it’s a key player in managing inflammation, regulating our immune system, and maybe even shaping the future of medicine.
In this conversation, you’ll explore the mind-bending complexity of the nervous system, discover how cutting-edge science is redefining how we treat diseases like rheumatoid arthritis and long Covid, and learn how a tiny chip implanted in the neck might one day replace whole classes of immune-suppressing drugs. Dr. Tracey shares metaphors, straight talk about medical myths, and a vision for a future where reprogramming the body’s reflexes could offer relief to millions.
Get ready for a journey that’s equal parts awe-inspiring and practical, as we unpack the true potential (and real-world considerations) of harnessing the vagus nerve’s power. Whether you’re a healthcare professional, a science nerd, or just someone searching for new answers, this episode invites you to see medicine in a whole new way.

Episode Highlights
- Vagus Nerve Complexity Unveiled — We’re only scratching the surface of understanding the vagus nerve’s vast, intricate network and its essential bodily roles.
- Inflammation: Friend and Foe — Inflammation is vital short-term, but when uncontrolled, it’s destructive and underlies many autoimmune and chronic diseases.
- Nervous-Immune System Interplay — The nervous and immune systems communicate reflexively, with nerves directly capable of controlling immune and inflammatory responses.
- Bioelectronic Treatments Emerge — Vagus nerve stimulation—via implanted chips—shows promise for conditions like rheumatoid arthritis without full-body immunosuppression risks.
- Individualized Nerve Fiber Functions — Each of the 200,000 vagus fibers controls specific functions, forming a body-wide symphony of precision responses.
- Not All Self-Help Fits — Lifestyle hacks can support vagus health, but serious disease often requires targeted nerve stimulation, not general wellness.
- Caution Against Online Misinformation — Vagus nerve advice online is often oversimplified or inaccurate; nuance and scientific backing are essential.
- Lifestyle Still Matters — Balanced diet, sleep, exercise, and community all help regulate vagus nerve tone and reduce chronic stress.
- Future Disease Applications Possible — Vagus stimulation may treat IBD, MS, and neurodegenerative or psychiatric conditions as research evolves.
