MDPRC retreat 2025
Thank you for that comment, I really appreciate it! 😊
Hey everyone! Join our journal club on October 10th (12pm EST) to discuss two short papers on weight stigma and language.
JC is drop in format: come once, come when you can.
Reach out to @shanaadise.bsky.social or myself to get the zoom link and papers. Please share!

Obesity increases the risk of Alzheimer’s disease, yet it remained unclear whether #obesity causes #neurodegeneration through the same mechanisms. A new study by Filip Morys in the lab of Alain Dagher used #OpenScience brain data to find the answer.

To determine distinct learning and decision-making profiles in obesity and binge eating (BE), we combined ecological momentary assessment (EMA) in a large online sample with a neuroimaging study. The figure shows the elements of the paper.
Binge eating (BE) is associated with reduced but more variable reward sensitivity. The panels show associations of BE with learning parameters and an fMRI-based reward sensitivity measure derived from the cue stage of an effort task (independent of learning).
Our big behavioral precision mapping preprint is out. Based on 1,486,950 observed choices in a reward learning task, we show that BMI is associated with higher and more variable learning rates. Binge eating was associated with lower reward sensitivity. #neuroskyence 🩺

🧵 Beautiful new preprint by @marishishi.bsky.social on the genetic architecture of impulsivity. With the UCSD team of Sandra Sanchez-Roige, Abe Palmer et al. and Lang Liu, Ziv Gan-Or @ukuvainik.bsky.social @filipkmorys.bsky.social @misicbata.bsky.social and others www.biorxiv.org/content/10.1...

New research from The Neuro shows that eating lots of ultra-processed foods is linked not just to obesity, but to changes in brain structure related to appetite and metabolism. These brain effects may help explain why these foods drive overeating.

We tried doing this but in a reduced (non MRI) sample for MR analysis. Might be interesting to redo it for the full sample! I’ll get back to you!
This is a cross-sectional study, but could depict a vicious cycle, where UPF consumption affects the brain leading to even more UPF consumption.
It also shows that UPF acts on the body not only through increases in adiposity.
Happy to discuss! 🤓

New paper! In ~30k people from UKBB we show that ultra-processed food consumption 🍔 is associated with structural integrity of feeding-related brain regions (Hpth/NAcc) 🧠 Some of the changes occur independent of obesity, through inflammation. www.nature.com/articles/s44... @alaindagher.bsky.social
Preprint w/ @filipkmorys.bsky.social on interplay of adiposity and AD genetics. Genetic risk ascertained from MAPT (H1), ApoE (E4) and polygenic risk score. Both adiposity and genetic risk are associated with brain atrophy in adulthood, but effects appear independent. www.medrxiv.org/content/10.1...
Neuroscience-related posts on Bluesky surged last week following an influx of users—including many neuroscientists. Chart by @callimcflurry.bsky.social.
I made a starter pack for the Society for the Study of Ingestive Behavior #SSIB for all interested in being a #SSIBling.
Please let me know if you would like to join the starter pack!
