Very happy to have this beautiful review published in Machine Learning: Science and Technology! @iopp-mlresearch.bsky.social

"Superintelligence" has arrived 😂
So this thing won gold in the international math olympiad and yet can't pass the simplest notion of 2nd grade math? lol...this is more like "reasoning" but "without understanding the subject that you are reasoning about"

Emergence of Brains This review traces how ideas from statistical physics evolved into foundational models of neural computation, shaping modern AI and culminating in the 2024 Nobel Prize in Physics.

The review/perspective piece @wbialek.bsky.social traces the roots of the 2024 NobelPrize back to Hinton
& Hopfield, highlighting their foundational contributions to neural networks. It explores the evolution of AI, considers its future through the lens of physics.

Because you don't burn the whole place to the ground for the fault of a few. This is dumb policy:

Friends, colleagues, I will be in NYC (Flatiron Institute) from Mon-Thu. Ping me if you want to meet up

Excited to share my PhD paper! In it, we use targeted 2-photon optogenetic stimulation to determine how V1 activity is read-out in a detection task. We found that network influence, not visual coding properties, predicted the impact of ensembles on behavior - contradicting our expectations (1/5).

Turns out that the “loudest” neurons are not always the most relevant ones. Great article about a fascinating and important result by @hayleybounds.bsky.social , graduate of @ucberkeleyofficial.bsky.social neuroscience.

Cool 👇

The extortion continues.... unbelievable.

Congratulations Roxana 👏

🚨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

Thanks for sharing these @wbialek.bsky.social

"Renormalization" by the great Phil Nelson
& "Theoretical Neuroscience" by none other than XJ Wang!
@xjwang.bsky.social thanks for the much needed missing textbook.

No better time to call or email your members of Congress. Next year’s NIH budget is being debated in the Senate.

Oh hey Tim and Gaute, fav duo :) looking forward to this
I will try. If I immediately die, it is your fault Tim @tpvogels.bsky.social and you will owe me a drink !

Here is my colleague Adam Riess, Nobel laureate, sharing his thoughts on advocating for science at a recent event at the US Capitol.

Hosting @lmprida.bsky.social , Liset who gave an update insightful talk
"Illuminating the cellular basis of hippocampal cognitive maps."

listen to XJ Wang
Fantastic discussion—his perspective feels like a breath of fresh air.
It’s refreshing to hear someone who isn’t confined to framing everything in terms of “cognitive tasks,” but instead views them as conduits for exploring the dynamical systems underpinning cortical function.

Do you study neural systems with feedback at different temporal-, spatial-, hierarchical-, data-, or computational- scales? Have you submitted your abstract to the "Neurocybernetics at Scale" symposium?
Due to multiple requests, new abstract submission deadline is 18 July! #AI4Science #cybernetics

Back in the US from a tour of science in Europe.
Ok, where were we?
Oh I see... from the official account of the White House 😂
