Rotem Botvinik-Nezer

Senior Lecturer (Assistant Prof.) @HebrewU Psych. Studying belief updating and placebo with models and brains. Trying to make science more open & reproducible.

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

[Rotem Botvinik-Nezer @rotembot]

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 https://t.co/PHexnHYyJ3 🧵👇

"Cognition Under the Skin"
Tuesday, Feb 10th, 11:30-13:10, Room D

with the wonderful @rotembot @pavelgoldstein @gadigilam @roitriester

[Liron Rozenkrantz @LironRozenkrant]

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!

[Rotem Botvinik-Nezer @rotembot]

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

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.

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 https://t.co/PHexnHYyJ3, including (10)
