Another absolutely astounding "gem" in the compact: abolish units that "belittle" conservative ideas -- while doing it in the name of an "intellectually open campus" 😮‼️

😂 Amazing! apparently no sense of irony (or consistency) whatsoever! 😂

Also completely incompatible with First Amendment.

Excellent analysis of the Trump compact for universities -- read it, recommend it, share it.

Among the big points: take away the law's predictability and fairness, and instead become entirely subjugated to arbitrary whims of the DOJ.

Dangerous and un-American.

Federal workers are speaking out on how the Trump regime is harming Americans:

"We stand here today at a moment of the greatest assault of our lifetimes on our freedoms. The US Constitution is being shredded... We are here to call on Congress to stand up and stop it."

Always exciting when someone reads one's work! Thank you for the interest and the quotes @ulisespereirao.bsky.social

And a shout out here to Adrian Bondy, @juliecharlton.bsky.social and @thomas-zhihao-luo.bsky.social, the wonderful co-first-authors who led the work.

Adrian is on the job market!

Friday’s AIND JC lead by Shawn Olsen and I on the Brody lab preprint ran 90+ min, unusual. Nice paper, spirited discussion. Make a clear argument that to grasp behavior we need multiregional, multi-neuron, simultaneous single-trial data. Below quotes from the paper.

This sounds great! Well done on doing it.

I'm part of a team crowd sourcing a database of examples of societal benefits due to federally funded science

if you get a chance, send us an idea and we'll write it up into the database!

A title and a link are enough to get us going 😊

Life is a crazy rollercoaster these days! Yesterday I was all proud of people in my lab, like @thomas-zhihao-luo.bsky.social and @timkimd.bsky.social and the paper they posted about.

Today? -- gah 😳🤯 straight corruption!

Up & down like that All. The. Time!

Breathe deep, everyone. It's a marathon

Omg that second highlight. Just straight corruption.

The H1-B visa thing is, like everything else in the Trump administration, set up to carve up exceptions for friends and punish enemies. It’s the authoritarian thru-line that stitches everything together.

You can make up your mind, as marked by nTc, long before you report a decision. And that nTc moment is not timelocked to any external referents (like the onset of the decision report).

Instead, nTc is a covert signal. Internal to the brain.

It was one of the brain's secrets... now revealed.
carlosbrody.bsky.social

That confirmed that in nTc, Thomas and Tim had found a neural marker of decision commitment (a.k.a. "making up your mind").
carlosbrody.bsky.social

They dubbed the estimated moment of the turn "nTc" and predicted that sensory inputs after nTc should not affect the animal's decision. They tested their prediction.

And whoa... the data (black), while noisy, matched the prediction (green) really well.
A sensory decision's sensitivity to sensory inputs is predicted to fall to zero after the neural marker of decision commitment -- and the data matches the prediction.

🤔.. when are you no longer sensitive to inputs? *When you've already made up your mind*.

Thomas and Tim figured that if they could pinpoint the time of the turn, then they could pinpoint the time the animal made up its mind. They developed a method to precisely estimate the moment of turning.

Recording in decision-making regions from many neurons at once revealed the neurons' collective evolution as decisions were made

Each decision had two phases: first, neural state was sensitive to sensory inputs; then, trajectories in neural state space turned and became insensitive to inputs.

What happens in your brain when you make up your mind?

Postdoc (soon faculty at U. of Utah) @thomas-zhihao-luo.bsky.social and ex-grad student (now Shanahan Fellow at Allen Institute) @timkimd.bsky.social have some answers in this new paper out in Nature!

The First Amendment and a Free Press are fundamental to freedom and to making America a great country.

Threatening to take away broadcast licenses for criticizing the president is a direct attack on the First Amendment. We have to speak up, be active, defend it.

I'm doing this: publicusaresearchbenefits.com . Join me.

Is it the best thing to do? I don't know. If you can think of something that fits you better, then do that! 💪🏼But do something.

And don't forget that science thrives on freedom, democracy, and strong institutions. We need to defend those too.

The Trump administration's assaults on great American successes, like this one, leave many of us scientists bewildered and not knowing how to respond.

But inaction is not an option. If you don't know what to do, put time and effort into figuring out what to do.

Other fun simultaneous recording results:

* brain-wide noise correlations are massive, as large as trial-averaged signals

* making up your mind causes a brain-wide change in decision-related neural activity.

* Cross-region coordination drops like a stone after after you make up your mind.

Complementary approach: simultaneous recordings allow analyses to see who leads and who lags. Among other results stemming from simultaneous recordings, in this preprint we show that during decision-making, frontal cortices and striatum lead, other regions lag.

This rule would have meant I couldn't do my Ph.D. in America.

I did do it in America. Became a professor. 12 thriving U.S. labs are now headed by trainees from my research lab. Like me, they are all working hard to enrich American knowledge and society.

With this self-harming rule, none of that.

Trump admin planning to change student visas from lasting for duration of academic program to fixed 4-yr term, and then much harder to renew
Could destroy US ability to attract global talent, particularly those seeking advanced degrees in STEM. The median time to complete a PhD is 5.7 yrs per NSF.
Trump Deals A New Immigration Blow To International Students
Trump officials have proposed a new rule limiting international students to fixed periods of entry, making a U.S. education more precarious.

As of today, I am a US citizen! 🇺🇸🇺🇸🇺🇸 I am very excited. 🎊

This wonderful country has given me a family, a career, and a community I love.

First duty as a patriotic citizen? 🇺🇸 Speak up to defend our Democracy, our Constitution, and our science, all under grave threat.

how incredibly hard and difficult. Sending thoughts and prayers but wishing I could do more.
