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. #neuroskyence 🩺 Now published in @cp-iscience.bsky.social www.cell.com/iscience/ful...

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

Our meta-analysis showed tVNS-induced pupil dilation (neuromadlab.shinyapps.io/tVNSPupilmeta/). We wanted to replicate with right-sided tVNS, but when accounting for sensation (even with initial matching) there was no effect compared to sham in our sample (N=94). www.biorxiv.org/content/10.1...

This is the first paper of my first grant 🎉. Work led by our PhD-student @cecivez.bsky.social together with @ulrichettinger.bsky.social & @nbkroemer.bsky.social

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.

Pulsed taVNS elicits pupil dilation. However, if sham feels as intense, there is not much left. Based on our comparatively large sample (94 participants, single-blind crossover), we show that a highly variable sham response explains this. #neuroskyence 🩺 www.biorxiv.org/content/10.1...

📢 𝗖𝗮𝗹𝗹𝗶𝗻𝗴 𝗔𝗽𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻𝘀 𝗳𝗼𝗿 𝗝𝗥𝗣 𝗦𝘂𝗽𝗲𝗿𝘃𝗶𝘀𝗼𝗿𝘀! Our former JRP Supervisor, Dr. @gabrielapavarini.bsky.social, shares what made her experience so rewarding. This year, we’re looking for PhD students or postdoctoral researchers to join us in exploring the 𝗣𝘀𝘆𝗰𝗵𝗼𝗹𝗼𝗴𝘆 𝗼𝗳 𝗗𝗲𝗰𝗶𝘀𝗶𝗼𝗻-𝗠𝗮𝗸𝗶𝗻𝗴 at 𝗷𝗦𝗰𝗵𝗼𝗼𝗹 𝟮𝟬𝟮𝟱.

Want to learn more about these truly eye-opening findings? You can run your adjusted meta-analysis using our living Bayesian meta-analysis, which is provided as a ShinyApp. Check it out here: neuromadlab.shinyapps.io/tVNSPupilmeta/

Does tVNS elicit replicable effects beyond BOLD responses in the brainstem? Yes, pulsed, but not conventional tVNS leads to robust pupil dilation in our new meta-analysis. Published in Brain Stim w/ @cecivez.bsky.social @akuehnel.bsky.social #neuroskyence 🩺 www.sciencedirect.com/science/arti...

I thought it could be nice to connect the community of researchers exploring body-brain interactions on bsky, so here is the Body-Brain Interactions Starter Pack! 🫀🫁👀🧠 #neuroskyence #academicsky Let me know if you would like to be added or know someone to add. Enjoy and share! go.bsky.app/Fwqeu32

In search of markers of tVNS, we looked at pupil dilation 👁️ doi.org/10.1101/2024... . Short pulsed but not continuous stimulation seems to work! You can also look at the data yourself neuromadlab.shinyapps.io/tVNSPupilmeta/. work w/@nbkroemer.bsky.social & @cecivez.bsky.social 🧠

After months of piloting and optimization, we are finally seeing high-quality recordings of tVNS-induced pupil dilation. @akuehnel.bsky.social also set up an automated QC report with several plots and is too humble to brag about it. Work w/ @cecivez.bsky.social #neuroscience

Such an inspiring WISE luncheon hosted by @therealspr.bsky.social today. Thanks to the speakers for sharing their experiences on how to build a more inclusive and diverse environment in academia. Great food for thoughts on how we as students and ECRs can also contribute! #2023SPR

Finally arrived in New Orleans right on time for #2023SPR (plus some city sightseeing)🤩 Looking forward to the next few days of talks, posters and social events, and to presenting some of our recent work on taVNS and decision-making on Friday! @therealspr.bsky.social
