Does the brain's response to non-invasive vagus nerve stimulation depend on the current state of the body? Our new paper suggests yes. www.sciencedirect.com/science/arti...
Non-invasive vagus nerve stimulation modulates Pavlovian bias in a state-dependent manner
The vagus nerve transmits vital signals between organ systems of the body and the brain. Despite growing interest in non-invasive transcutaneous vagus…

Can your brain's white matter proxies of inflammation re-identify you like a fingerprint? Turns out: yes, and we used this to psychometrically evaluate diffusion basis spectrum imaging and to detect depression-related changes in the cingulate bundle. #neuroskyence 🩺 www.medrxiv.org/content/10.6...
A teaser for our upcoming preprint on the short-term test-retest reliability of diffusion basis spectrum imaging. Voxel-level reliability of hindered fraction (a proxy measure of edema) in white matter is good, particularly close to cortical gray matter. W/ @lhkal.bsky.social @akuehnel.bsky.social
I am enjoying a few uninterrupted hours of plotting today. Finally got my hands on our diffusion basis spectrum imaging data, and it looks good, particularly in white matter voxels. I hope we will have a preprint coming out in a few weeks, led by @lhkal.bsky.social & @akuehnel.bsky.social
Last preprint 🎶(of the year). If vagus nerve stimulation alters motivation by amplifying internal signals, then bodily states should matter. Using milkshake vs. water loads, we show that tVNS-induced changes in Pavlovian bias are dependent on hunger. #neuroskyence 🩺 www.biorxiv.org/content/10.6...
