Vagally Understood
The vagus nerve is vaguely understood by science. We're working on it. Explore the research behind vagal tone and vagus nerve stimulation.
- How tVNS works: an interactive 3D walk through one pulse, from the clip on the tragus to the nerve endings that feel it.
- Tragus current-flow simulator: an interactive model of where each tVNS pulse goes through skin, subcutis and cartilage.
- The Vagal HRV study: take part with your own device and a chest strap.
- Research Edition Digital Upgrade: full parameter control, sham mode and data logging for your device.
- Vagal Tone Test: a quick self-assessment.
