Summary

This study tests whether a mild electrical pulse on the ear (over the vagus nerve) can improve reaction time in healthy adults. Thirty participants will receive a 5-minute stimulation using a TENS unit, and their reaction time will be measured before and after. It is a small, early-stage study exploring a possible link between nerve stimulation and mental quickness.

What this could mean

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

Active substance
non-invasive vagus nerve stimulation via TENS unit
What this could lead to
If it works, this could point toward a simple, drug-free way to boost reaction time for healthy people.
What could go wrong
This is a very small, early study in healthy volunteers, so results may not apply to others. The effect, if any, is likely small and temporary.
