Ear zaps may tune your nervous system – scientists test best frequency
NCT ID NCT07526402
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study will test how stimulating the ear with mild electrical pulses at different frequencies affects heart rate, breathing, and blood pressure in 36 healthy adults. Each person will try five different stimulation settings (including a fake one) in separate sessions. The goal is to see which frequency most strongly influences the body's 'rest and digest' system.

- Active substance
- transcutaneous auricular vagus nerve stimulation (taVNS)
- What this could lead to
- If successful, this could help identify the best stimulation frequency for future treatments of conditions like anxiety, epilepsy, or depression.
- What could go wrong
- This is a small, early-stage study in healthy volunteers, not patients. Results may not apply to real-world medical conditions.
