Pupil dilation may reveal how well vagus nerve stimulation works
NCT ID NCT06335199
First seen Nov 01, 2025 · Last updated May 22, 2026 · Updated 23 times
Summary
This study looked at how the pupil changes size when stroke survivors and healthy adults receive mild electrical stimulation to the vagus nerve through the ear. Researchers wanted to see if stimulating both ears at once causes a bigger pupil response than stimulating just one side. The goal is to learn how the brain reacts to this stimulation, which could help design better rehabilitation therapies for stroke recovery.
