Scientists map brain's response to ear touch in healthy volunteers

NCT ID NCT06825364

First seen Nov 01, 2025 · Last updated Jun 23, 2026 · Updated 25 times

Summary

This study looks at how the brain responds when different spots on the ear are gently touched. Eighty healthy volunteers will wear a cap with infrared sensors to measure brain activity while a plastic filament stimulates points on both ears. The goal is to see if the brain reacts differently depending on which ear point is touched, which could help understand how the ear is connected to the brain.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

auricular stimulation (von Frey filament)

What this could lead to

If successful, this could help map how the brain responds to touch on different ear points, potentially guiding future treatments for pain or other conditions.

What could go wrong

This is a small, early-stage study in healthy volunteers, not patients. It only measures brain signals, not treatment effects, so results may not apply to real-world medical use.
