Awesome! Looking forward to seeing you there, and let's hope they do not take place at the same time😅!

Do you have experience turning amateur data analysis scripts into robust, scalable code? I’m hiring (hourly pay) to professionalize Python scripts for scientific data analysis, making them reusable across multiple datasets.
Tromsø/Norway-based candidates preferred, but all are welcome! DM me!

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.

I'm very excited that this is out as preprint. In this study, 370 participants completed up to 30 runs of reward learning. We see that BMI and and Binge eating are associated with distinct RL patterns. Includes hierarchical models using Stan (+ many hours of sampling) and MRI data of an effort task

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 🩺
www.medrxiv.org/content/10.1...
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).

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
