- "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"
- 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. journals.aps.org/prxlife/abst...
- Both submitted work accepted @sfn.org "Deep cortical layer stimulation reveals state-dependent changes in neural excitability" “Parametric Stimuli Reveal Functional Subcircuits in Visual Cortex” Though I am concerned that given the news on travel restrictions we may have a low attendance.
- Friends, colleagues, I will be in NYC (Flatiron Institute) from Mon-Thu. Ping me if you want to meet up
- Reposted by Nima DehghaniExcited 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).

- Reposted by Nima Dehghani🚨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

- 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.

- Reposted by Nima DehghaniThe full ruling explaining why NIH grant cuts are illegal came out today. It's just as blistering as the judge's oral remarks. And it uncovers fresh details in DOGE's role orchestrating the cuts — and on the cuts at Columbia. Here are my top highlights from the 103-page ruling. 🧵
