New preprint, on 'sequence filtering'. Led by @CianaDeveau, Z Zhou. We see this as a key step forw on how cortex works. All cortical areas have dense exc-exc recurrent connectivity. What do these connections do, esp in sensory ctx? Our data say: they do dynamics/time. 1/4

"the proposed changes would affect everything from transportation and housing to public health, workforce development and public safety. For state and local governments, this amounts to a fundamental transformation..." !! Jed Herrmann, in Governing governing.com/management-and…

Reading the Hobbit to kid now

pete@pete_churchill

@bazashc Have you ever read it??? It’s 100% not a children’s book and whoever says that is lying to you. Not only is the vernacular dated and elaborate but the sentence structure and lengthy writing is often hard to get your head around as an adult. Love that book! but it’s not for kids

"Pharma cos and biotechs in particular are warning about the downstream consequences... 'The proposed changes to funding decisions could introduce unpredictability that would weaken the scientific ecosystem." PhRMA spokesperson Alex Schriver said. Yes axios.com/2026/07/09/omb…

@jacklindsay @sofroniewn there's been discussion recently about whether a brain is like a computer in any way. I continue to think that while LLMs/AI systems differ in many biophysical details from biological brains, they capture something about network computation neuroscience can learn from.

Interesting work from @jacklindsay @sofroniewn et al from the mech interp group at Anthropic. Quick take: these are abstract representations which do have similarities to human brain features. #neuroscience #neuroai 🧪 1/2 transformer-circuits.pub/2026/workspace…

@JasonSynaptic Exactly! Happy fourth.

@HistedLab He has no idea what he’s talking about. It’s laughable that he thinks industry could replace the NIH. NIH funded labs train almost every scientist who ends up in industry . As you state, the science funded by NIH is the bedrock for biotech and the govt MAKES $ on that investment!

It is sad that Scott Atlas doesn’t understand basic economics. Paul Samuelson wrote about public goods—why NIH has been such a stunning success—more than 75 yrs ago. Also, to see why Atlas urges ending US success, just look at who elevates him: pro-privatization billionaires. 1/

It’s going to take all of us. Each of us can find the courage to do something. I have this shirt too. It gets it right: the arc of history is not going to bend itself. “So get involved.” Embrace the flag. American symbols are for those who believe in America’s ideas. /end

But we have been here before. Robber barons a century ago used ill-gotten gains built on sociopathy and monopoly power to corrupt American ideas. There is a government means to fix this. Brandeis and others picked that fight. And built public institutions to improve society.

“We hold these truths to be self-evident.” On the 250th. This shirt gets it right: America is an idea, of freedom, equality, and a fair shake for all. 1/

If Scott Atlas thinks private entities are going to take on projects with basic science timelines and return schedules, I’ve got beachfront property to sell him in Phoenix.

Last, abolishing the NIH and NSF would create a funding vacuum. I hesitate to even engage with this utterly naive view of economics and science, but I’ll note CZI and HHMI’s dramatic course changes, Bell Labs support by govt contracts, and check out Wellcome/CZI/HHMI budgets.

Mark Histed@HistedLab·2 Tem

As we celebrate America’s 250th birthday, we can do better: we can support the public interest, freedom-including good health, equality for everyone, curbing the tyranny created by billionaires, and a free and fair marketplace of ideas. The opposite of what this is.

I’m not going to link the Bezos Post piece and give them clicks. It’s really not worth your time. I’m on vacation today with the family but I’ll put this thread together into a post soon.
