Are these yours? They're very good, I really like the close up :)

🚨New paper🚨

Neural manifolds went from a niche-y word to an ubiquitous term in systems neuro thanks to many interesting findings across fields. But like with any emerging term, people use it very differently.

Here, we clarify our take on the term, and review key findings & challenges rdcu.be/ex8hW

A neural manifold view of the brain - Nature Neuroscience Recent advances in neuroscience have revealed how neural population activity underlying behavior can be well described by topological objects called neural manifolds. Understanding how nature, nurture...

Check out our new review/perspective (w/ @juangallego.bsky.social & Devika Narain) on neural manifolds in the brain! It was a lot of fun to think through these ideas over the past couple of years, and I'm excited it's finally out in the world!

New paper @pnas.org with Lola Beerendonk, Jan Willem de Gee, Simon van Gaal and others, on pharmacological shifts of performance. We combine psychophysics and pupillometry with computational modeling to provide interesting insights linked to PV-SST-VIP circuits: www.pnas.org/doi/10.1073/...

Memory by a thousand rules: Automated discovery of functional multi-type plasticity rules reveals variety & degeneracy at the heart of learning Synaptic plasticity is the basis of learning and memory, but the link between synaptic changes and neural function remains elusive. Here, we used automated search algorithms to obtain thousands of str...

We just pushed “Memory by a 1000 rules” onto bioRxiv, where we use clever #ML to find #plasticity quadruplets (EE, EI, IE, II) that learn basic stability in spiking nets. Why is it cool? We find 1000s!! of solutions, and they don’t just stabilise. They #memorise! www.biorxiv.org/content/10.1...

Glad to see it on paper! BTW, I enjoyed your Cosyne talk about it, I'll dive into the full story now.

Against Language Barriers: A Call to Protect International Education in Dutch Academia

Dutch universities want to prohibit many educational programs from being taught in English, folding to the government's demands. If you're against this serious hit to the international prestige and quality of Dutch institutions, consider signing this letter: openletter.earth/against-lang...

Save the date: for those in the Amsterdam area, the date for this year's Amsterdam Neuroscience Meeting is a bit later than usual: January 16th 2026. It's a great opportunity to connect with other researchers in the Amsterdam area. Hopefully see you there!

Fantastic initiative, and a prime example of the benefits of large-scale scientific collaboration. Thanks @jeromelecoq.bsky.social for leading the effort, looking forward to the next steps!

Perfect, thanks!

Is the deadline at any particular time of April 10th? Or is it ok as long as it's still April 10th somewhere?

Upcoming (April 28 - May 2) free, 5-day webinar "Advancing Computational Neuroscience Through Collaborative Learning". With speakers from Afrika, US and Europe, and organized by Jessica Oparebea and collaborators at the University of Ghana. Please spread the word, and sign up if you're interested!

Remember, today is the last day to apply for the Computational and Cognitive Neuroscience Summer School, June 29-July 20 2025, Suzhou (China). Join us this summer! Link: www.csh-asia.org?content/2621=

Thanks @behrenstimb.bsky.social and @elife.bsky.social for using your voice to highlight these issues. This concerns not only US researchers, but all the community (as they same trends are also reaching places like UK and the Netherlands...). Glad to see people still fight back and talk about it.

Science Under Threat in the United States: How scientists and institutions should respond Individual researchers and university leaders need to make the case for science to their elected representatives and to the public at large.

Science is under threat in the US. @elife.bsky.social have commissioned a series of articles discussing the implications and what we can do. The first three articles are now live. More to follow:

Theoretical Neuroscience | Understanding Cognition | Xiao-Jing Wang | This textbook is an introduction to Systems and Theoretical/Computational Neuroscience, with a particular emphasis on cognition. It consists of three parts:

Fantastic textbook of theoretical and computational neuroscience by @xjwanglab, covering everything from biophysical circuits to cognition, full-brain models, neuro-AI and computational psychiatry. I can't recommend it enough for anyone in the field www.taylorfrancis.com/books/mono/1...

This looks quite interesting, and more importantly, it feels so fresh! I'll definitely stop by :)

Model-Based Neuroscience and Cognition Summer School Visit the post for more.

There is again a model-based neuroscience summer school from Aug 4-8th in Amsterdam! modelbasedneurosci.com

Fantastic opportunity to join an equally fantastic lab!

Our new paper on ignition during conscious perception, spearheaded by @ulysse-klatzmann.bsky.social and @seanfw.bsky.social. A detailed large-scale brain model tackling fundamental questions and presenting experimental predictions tested and confirmed. More details in Ulysse's thread below!

It's been a pleasure working with you!

Third: network with students and faculty from all over the world, and take this chance to explore China if you come from abroad. For many European citizens, it is now possible to travel to China for study or tourism for 30 days without visa, which is an amazing and unusual opportunity.

Second: we have a fantastic set of lecturers and faculty coming from top universities and industry, such as Michael Haüsser (UCL), Alex Reyes (NYU), Si Wu (Pekin Univ), Srdjan Ostojic (ENS), Kevin Wenliang Li (DeepMind) and Gustavo Deco (UPF), with Xiao-Jing Wang (NYU) leading the effort.

First: the schools focuses on the interface between cognitive and computational neuroscience, with strong links to psychiatric disorders as well as neuro-AI. Top lectures are combined with hands-on tutorials and student projects to make sure you get the most out of this learning experience.

Please spread the word!! We are accepting applications for the Cold Spring Harbor Asia Computational and Cognitive Summer School in Suzhou, China. Dates: June 29 to July 20 of 2025. Application deadline: March 31. #computationalneuroscience. For the top three reasons to attend, see thread below:

Great to see these AI workflows for neuroscientific data analysis popping up (although perhaps a few figures illustrating the results would have made it more attractive? Very interesting nonetheless)
