Effects of non-invasive vagus nerve stimulation on pupil dilation are dependent on sensory matching https://www.biorxiv.org/content/10.1101/2025.06.13.659318v1
Pupil dilation is an established biomarker of arousal, and studies have shown that non-invasive vagus nerve stimulation (taVNS) elicits pupil dilation. Here, we find that it depends on sensory matching.

There is also good news embedded in the report. We find that taVNS briefly purturbs the correlation of the pupil dilation trace of the left and the right eye. This novel marker is not as strongly associated with sensory ratings. But it makes sense since we stimulate one side of the vagus.
