Now out @NatureComms! rdcu.be/dN6iqWith
With @bogpetre (co-first) @torwager @Na_Friedman @fMRIstats @martaceko we show with fMRI & N=392 that placebo analgesia is driven by changes in brain systems related to affective & cognitive processes, not nociceptive pain processing
Our beliefs shape our response to treatment. Pretty amazing, right? @SIPSplacebo But do placebo effects operate via low-level perceptual or high-level cognitive and affective processes? Preprint w/ @bogpetre @martacek @fMRIstats @Na_Friedman @torwager doi.org/10.1101/2023.09.21.5… 🧵👇

"Cognition Under the Skin"
Tuesday, Feb 10th, 11:30-13:10, Room D
with the wonderful @rotembot @pavelgoldstein @gadigilam @roitriester

Also, excited and grateful that #ISCOP2026 committee accepted our not-so-conventional symposium, “Cognition Under the Skin.”
We’ll explore how cognition shapes downstream bodily processes, from pain & trauma to symptom dynamics & inflammation.
It’s going to be fascinating!
Well, my visibility here may have become non-existent, but I’ll still share our lab’s planned presentations at #ISCOP2026 this week: 3 posters, 2 talks, and 1 symposium.
Super proud of the students for all their hard work!
And thanks @NotebookLM for the great flyer ✨
And alongside that: we examined how expectations are formed from multi-value social cues,
and how they shape both pain and visual perception.
Integrating behavior, neuroimaging, and computational modeling.

Predictive processing models posit top-down influences of internal models on brain processing at multiple levels, including sensory processing. But they don't specify the details. How deep does predictive information penetrate into perception? What are the limits? New paper on prediction in pain and vision in PLoS Computational Bio, with @rotembot and @fMRIstats

Conspiracy beliefs famously resist correction, right?
WRONG: We show brief convos w GPT4 reduce conspiracy beliefs by ~20pp (d~1)!
🡆Tailored AI evidence rebut specific arguments offered by believers
🡆Effect lasts 2+mo
🡆Works on entrenched beliefs

It was a pleasure talking with @fMRI_today about analytical variability #narps doi.org/10.1038/s41586-020-2…, promoting open & reproducible science (doi.org/10.1016/j.neuroimage…; doi.org/10.1016/j.bpsc.2022.…; rdcu.be/dxcnh), placebo effects doi.org/10.1101/2023.09.21.5…, #OHBM, & much more!
🎙 Join us in this Neurosalience episode with @rotembot and @fMRI_today, where they dive into the nuances of neuroimaging analysis—from the impact of shared data to the intriguing interplay between brain perception and pain.

After 5 years of collecting data on this project--the largest placebo neuroimaging study to date--it's wonderful to be able to take fMRI correlates of placebo analgesia to the next level of scale!

Seeing chronic back pain as due to the mind or brain can help heal it.
Check out our paper published today in JAMA Network Open, using natural language methods to study patients' **pain attributions**

placebos mainly operate via higher-level processes, and transfer between pain modalities. These findings open new directions for how to harness placebo effects and placebo-like processes to improve clinical care. Read our preprint for more doi.org/10.1101/2023.09.21.5…, including (10)
individual differences, surprising reversed neural placebo-induced responses in the transfer condition, and more.
