About a month late posting this, but here's a new project with @ericschulz.bsky.social, @akjagadish.bsky.social, @marvinmathony.bsky.social and Tobias Ludwig We are using LLMs to propose cognitive models in learning and decision making data. Presenting this work at RLDM! arxiv.org/abs/2502.00879

Today I discovered a dramatic science communication fight on the internet. Thanks @mabuice.bsky.social for debunking me when taking a side naively. I deleted my post. Grab popcorn and watch this:

I wrote a thing for @thetransmitter.bsky.social. The attack on scientific infrastructure happening in the US shows that relying on any one country is not a good option for science. We need to start supporting and building international, decentralised infrastructure for science.

So why "perturbation [data] are more special" ? Here is a toy math model: 2 area system can be feedforward or recurrent (hypothetical mechanism 1 or 2) and produce the same activity distribution. With an opto inactivation you separate the two hypothesis right away. Is that convincing?

"Far-right populists much more likely than the left to spread fake news – study" Massive study covering 32m tweets from 8,000+ MPs across Europe points to the inescapable conclusion that the Far Right lie the most. (All other parties are very broadly on par.) www.theguardian.com/world/2025/f...

I am deeply worried by the withdrawal of the US from the World Health Organization. I worked at WHO for ~2 years at WHO's Global Programme on AIDS, a worldwide response to the HIV pandemic & international cooperation was critical. The US should not withdraw from WHO's global health cooperation.

Pre-print 🧠🧪 Is mechanism modeling dead in the AI era? ML models trained to predict neural activity fail to generalize to unseen opto perturbations. But mechanism modeling can solve that. We say "perturbation testing" is the right way to evaluate mechanisms in data-constrained models 1/8

There's still time to apply to the Paris NeuroCourse. This year we'll have two 2-photons, miniscopes, neuropixels, voltage imaging, patch-clamp, and of course an amazing list of lecturers: parisneuro.ovh 2 weeks of neuroscience lectures and techniques in Paris!

New round of spike vs rate? The concentration of measure phenomenon can explain the emergence of rate-based dynamics in networks of spiking neurons, even when no two neurons are the same. This is what's shown in the last paper of my PhD, out today in Physical Review Letters 🎉 tinyurl.com/4rprwrw5
