Ear zaps and pupil dilation: a window into brain learning?

NCT ID NCT05386563

First seen Jan 07, 2026 · Last updated Jun 16, 2026 · Updated 22 times

Summary

This study tested whether a gentle electrical stimulation on the ear (taVNS) changes how the pupil reacts and how quickly people learn a simple task. Twelve healthy adults completed computer-based tasks while their pupil size and brain activity were recorded. The goal was to understand the body's response to the stimulation, not to treat any disease.
