BREAKING NEWS:
The 2021 #NobelPrize in Physiology or Medicine has been awarded jointly to David Julius and Ardem Patapoutian “for their discoveries of receptors for temperature and touch.”
It's @PuG2021online time and our lab will present 3x this year.
We will talk about recent work on extensive repeated testing of reinforcement learning and tVNS-induced changes in stomach-brain coupling & food liking in patients with anhedonia.
Short 🧵 w/ details
New preprint. We introduce a gamified task optimized for longitudinal studies of value-based decision-making and learning: @Influenca_Game.
The preprint includes ICCs based on the first set of ~2900 runs (150 trials each).

When we started doing vagus nerve stimulation, we vowed to publish our null results as diligently as the shiny effects.
In our new preprint, we show that acute tVNS does not robustly alter liking or wanting ratings of food in healthy people. https://t.co/s1QfbAOrcv
Published in Appetite now: We show that lower trial-to-trial variability in effort for the same reward is associated with cognitive restaint of eating behavior.
Excellent master thesis work led by @MechteldHoekOst who is now working as a PhD student in Jen Svaldi's group.
While we need to stay at home, you can join the fight against pathogens. How? By playing @Influenca_game! Your task is to find the best medication in an ever-changing environment. Grow your virtual lab and help us science on by playing & RT #wevsvirus https://t.co/TfNtl4U9Bq
@ukppretreat@glassybrain@cornu_copiae@neuroMADLAB@uktuebingen@uni_tue@Influenca_Game 6. We found that the app can provide a rich dataset to study interindividual differences in the interplay of reward processing and fluctuating mood and homeostatic states. How does this relate to different personalities, habits or mental disorders? Stay tuned for further updates.
New preprint:
Despite the interest in vagus nerve stimulation as a treatment for depression, research on acute mood effects is scarce.
We show that taVNS improves mood recovery after a challenge, but does not alter mood during active stimulation.
