The Vagus Nerve, Decoded
What the science actually says about your body's most misunderstood nerve.
Most of the vagus-nerve shelf was written by machines and checked by no one. This one was also written by a machine — and then checked, obsessively, by a practising doctor who threw out everything that didn't hold up (including, once, a study the AI had invented).
Inside the book
- Why the vagus is not “80% of your nerves” — and the precise anatomical fact that slogan was inflated from
- The 2026 expert reckoning over Polyvagal Theory — and the live argument the bestsellers never mention
- The inflammatory reflex: how a brake pedal for your immune system was discovered by cutting one nerve
- Every popular “hack”, graded by the evidence — from breathing (A) to gargling (D)
- The July 2025 FDA approval that opened a third pillar of medicine — bioelectronics
- The one-page programme you can start tomorrow
The honest part
We told you on the cover, and we'll tell you again here: a machine wrote this book. The dishonest thing was never using the machine — it's hiding it, and never checking whether a word of it was true. So we did the opposite, out loud. Here's exactly how it was made, and here's the corrections page where we fix what we get wrong, in the open.
