On top of all the science, attending the school will give you the chance to explore China and the Shanghai region. Citizens from multiple countries (including many Europeans) don’t need a visa to travel and stay in China for up to 30 days. It’s a golden chance :)

Hybrid neural–cognitive models reveal how memory shapes human reward learning - Nature Human Behaviour Using artificial neural networks applied to human data, Eckstein et al. show that good models of reinforcement learning require memory components that track representations of the past.

This work by @mariaeckstein.bsky.social et al is a nice example of how progress in psychology can be expedited with machine learning.

How long before this type of approach is expected for models-of-behavior papers? My guess: not long. (If you are a trainee, nudge!)

Fantastic and very comprehensive work, @annhuang42.bsky.social and @kanakarajanphd.bsky.social. We published something on this topic just last year, but at a smaller scale (200 RNNs and only two tasks): journals.plos.org/ploscompbiol.... Perhaps you find it useful, I'll definitely study yours!

That looks a lot like my tenure-track years! My personal record was 15 proposals (of different sizes and flavors) rejected consecutively over ~3 years. But the 16th was the charm, and it went better from that moment. We can only learn from it and keep trying 🙂

Functional connectivity drifts during sleep as a marker of fluctuations in the level of consciousness Abstract. During the wake–sleep cycle, consciousness waxes and wanes, and this is thought to be reflected in varying levels of integration between brain ar

We recently did just that to validate a method to measure functional inter-area interactions, and it worked like a charm (academic.oup.com/nc/article/2...). It also puts the model results appear early in the story (in our case, in fig 3 of a 11-fig paper).

Both are certainly possible. A modeling at the end serves as a 'postdiction' (a la Abbott) and integration mechanism for the main message of the paper, but I confess I recently had much fun with models first and then having the data analysis reveal whether we were right (i.e. predictive role)

🔬 We're hiring a Junior Group Leader for Data-Driven Digital Twins/System Models in medicine/life sciences at @uni_goettingen! Perfect opportunity for early-career researchers who want to:
- Lead their own research group
- Work at the intersection of AI, simulation, and biomedicine

Europe's MSCA postdoctoral fellowships are now attracting many researchers who would have gone to the US. So the payline has dropped below 10% (~1,600 fellowships to 17k applicants). Super tough situation. One more reason to double the next Horizon budget, as proposed by the EU Commission.

The missing half of the neurodynamical systems theory Bifurcations—an underexplored concept in neuroscience—can help explain how small differences in neural circuits give rise to entirely novel functions.

Really hoping bifurcations are the new manifolds. What a time to be alive 🥲

q.e.d Science Critical Thinking AI for constructive criticism and science evaluation

Surprisingly good 'AI reviewer' tool from @odedrechavi.bsky.social to help you find gaps and improve your manuscripts. I've only run it through a couple of my (published) papers, but the feedback was mostly on point and in line with our ongoing directions for improvements: www.qedscience.com

Oded, this works surprisingly well for a LLM, much better than what I expected (even though the model was not fully confident in my research area). I can see how it could be useful to refine your manuscripts before submission. Congratulations!!
