New preprint! We observed a nonlinear relationship between pupil dilation and the intensity of transcutaneous auricular #vagus nerve stimulation (#taVNS) in adult humans. We discuss the potential role of stimulation parameterization in using #pupillometry as biomarker of taVNS’s neuromodulatory effects.

Our new #trendsinhearing paper is out!
We found evidence that anticipation of upcoming listening difficulty impacted baseline pupil size and the shape of the task-evoked pupil response during 60-sec story listening.
Led by former UMD postdoc Mike Johns in collaboration with @jzsimon and many others.
