Exploring the effects of taVNS on pupil response and learning

The Effect of Transcutaneous Auricular Vagal Nerve Stimulation (taVNS) on Pupillary Response and Perceptual Learning

NA · NYU Langone Health · NCT05386563

This study is testing if a new type of nerve stimulation can improve how people learn and respond to tasks by looking at changes in their pupils and brain activity.

What this trial studies

This study investigates the effects of transcutaneous auricular vagal nerve stimulation (taVNS) on pupillary response and perceptual learning. It consists of two parts: the first evaluates taVNS and sham stimulation during a passive task while measuring pupillary response, and the second assigns participants to receive taVNS, sham, or no intervention during a go/no-go task to assess perceptual learning across three sessions. The study also incorporates electroencephalogram (EEG) measurements to gather additional data on brain activity related to these tasks.

Who should consider this trial

Good fit: Ideal candidates for this study are healthy individuals aged 18 to 65 with normal audiometric testing.

Not a fit: Patients with co-morbidities such as cardiomyopathies, arrhythmias, or those with implantable devices will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance our understanding of how taVNS influences cognitive processes and pupillary responses, potentially leading to new therapeutic approaches.

How similar studies have performed: While the specific approach of taVNS in this context may be novel, similar studies exploring vagal nerve stimulation have shown promising results in other areas.
