Nature Sci Rep publishes incoherent AI slop. eLife publishes a paper which the reviewers didn't agree with, making all the comments and responses public with thoughtful commentary. One of these journals got delisted by Web of Science for quality concerns from not doing peer review. Guess which one?

So excited to see our latest paper out today in @natcomms.nature.com! Studies led by the amazing @margestelzner.bsky.social www.nature.com/articles/s41.... VTA GABA neurons have a unique role in economic decision making - they integrate reward seeking motivation and the current cost of seeking

Good morning everyone! Suitably following the #dopamine dinner, we have our #dopamine symposium at 9:30am in SDCC room 6B! ‘Beyond Value: Non-canonical roles for dopamine in aversion and reward’ Come join us! 🧠 🧪

If you're at SfN on Monday, come by poster board II10 to see how fentanyl changes cell type-specific encoding of choice outcomes in the striatum to influence decision-making phenotypes. Looking forward to seeing some cool science and supporting SfN during these difficult times!

Delighted to see this finally out: rdcu.be/eO9oW We tested whether brief striatal dopamine release events influence the vigor of skilled movements. Despite popular belief, we did not find any evidence linking rapid dopamine dynamics to motor vigor on a moment-by-moment basis.

Nature suggests you use their "Manuscript Adviser" bot to get advice before submitting I uploaded the classic Watson & Crick paper about DNA structure, and the Adviser had this to say about one of the greatest paper endings of the century:

I first heard Jack DeJohnette as part of the Keith Jarrett trio when I was ~14. I didn’t like his drumming and thought it sounded sloppy. For whatever reason, it clicked with me much later. Here’s a 🔥 clip I discovered recently. RIP JD youtu.be/a3CZHr5uiNM?...

We have an open NIH-funded postdoc position in the lab to study circuit and neurochemical mechanisms of cognitive and motivational deficits in opioid withdrawal. Apply here: recruit.ap.uci.edu/JPF09885 or message/email for more information.

I'm recruiting a PhD student to study how enkephalins affect cognitive processing in the rodent frontal cortex. The project uses pharmacology, multi-electrode recordings, and fiber photometry, and is funded by NIDA. Please share with trainees applying this cycle. Thanks!

How does the brain decide? 🧠 Our new @nature.com paper shows that neural activity switches from an 'evidence gathering' to a 'commitment' state at a precise moment we call nTc. After nTc, new evidence is ignored, revealing a neural marker for the instant when the mind is made up. rdcu.be/eGUrv

Though it’s traumatic for me to bring this up, I was targeted by a group allied with Turning Point USA in 2018, with the help of Tucker Carlson on Fox. My home address circulated online and I got death threats. 1/

Director Bhattacharya says there are no banned words at the NIH. The data suggest otherwise.

Thank you to everyone who contributed by spreading the news, submitting abstracts, reviewing the submissions, and offering kind words of support. I am grateful and smiling

TL;DR: 5 justices say Trump doesn't have to immediately restore the funding, but 5 *also* signal that the underlying directives are unlawful. That sends a fairly strong (if mixed) message that Trump will lose these cases *eventually,* but only once they're brought in the Court of Federal Claims.

This op-ed from NIH director Jay Bhattacharya is *infuriating*. He says we have to stop funding mRNA vaccine research because it hasn't "earned public trust." Motherfucker, WHO DID THAT.

I’m excited to share my latest paper, in which we used latent state modeling to reveal how fentanyl shapes decision-making dynamics in rats. Here’s a summary of what we found (thread). www.biorxiv.org/content/10.1...

A landmark volume, The Handbook of Dopamine, is now online: www.sciencedirect.com/handbook/han... Big kudos to the editors, Stephanie Cragg and Mark Walton, for putting this together.

The NIH budget will INCREASE by $400 million — not slashed by 40%, as Trump proposed — according to a proposal by Senate appropriators, says Sen Murray. "Some have asked if there will even be an NIH by [2029]. The commmittee's resounding message is yes—Congress has your back", she says.

NIH and FDA hosted a workshop on July 7 on efforts to reduce the use of animal models in research, NIH has formally announced a policy change. The agencies have invited comments through the workshop’s webpage. PLEASE COMMENT. The portal will be open until 5pm ET on Monday, July 14 (TODAY).

The sycophantic tone of ChatGPT always sounded familiar, and then I recognized where I'd heard it before: author response letters to reviewer comments. "You're exactly right, that's a great point!" "Thank you so much for this insight!" Also how it always agrees even when it contradicts itself.

I sometimes struggle to identify what my biggest issue is with NIH Director Bhattacharya: his lying, lack of qualification, corruption, sycophancy, or extremism. But this is a big one: He’s so ignorant about how NIH works that it’s completely and totally embarrassing.

Our latest work: www.biorxiv.org/content/10.1... We show that corticostriatal ramping activity can't readily be explained by movements using motion tracking, and that ramping can't readily be explained by reward anticipation in mice performing timing and Pavlovian tasks.

Highly recommend!

Just in: NIH staff have been instructed to REINSTATE these ~900 grants to comply with the court order, per sources. This comes after staff were also directed to cease any further terminations. You can see the lists grants to be reinstated in my post below.

A key takeaway from 20+ years of computational RL is: model-free=automatic, model-based=deliberate. My new paper w/ @benedek.bsky.social challenges this view, suggesting that MB algos are more ubiquitous, & automatic processing more sophisticated, than currently thought: www.pnas.org/doi/10.1073/...

THIS IS IT! THIS IS HUGE!! PLAINTIFF'S WIN!! Judge Young rules that the NIH grant terminations at issue in these cases are illegal and therefore vacated. BOOM!

Our work, out at Cell, shows that the brain’s dopamine signals teach each individual a unique learning trajectory. Collaborative experiment-theory effort, led by Sam Liebana in the lab. The first experiment my lab started just shy of 6y ago & v excited to see it out: www.cell.com/cell/fulltex...
