A study led by Cina Aghamohammadi is now out in ‪@natcomms.nature.com‬! We developed a mathematical framework for partitioning spiking variability, which revealed that spiking irregularity is nearly invariant for each neuron and decreases along the cortical hierarchy.

Over the past year, my lab has been working on fleshing out theory + applications of the Platonic Representation Hypothesis.

Today I want to share two new works on this topic:

Eliciting higher alignment: arxiv.org/abs/2510.02425
Unpaired learning of unified reps: arxiv.org/abs/2510.08492

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."

The neural control & computation lab is recruiting!

If you're interested in using large-scale neural population recordings to study how the brain learns to produce complex and flexible behaviours, please get in touch.

Many treat uncertainty = a number. At Apple, we're rethinking this: LLMs should output strings that reveal all information of their internal distributions. We find that Reasoning, SFT, CoT can't do it - yet. To get there, we introduce the SelfReflect benchmark.

Did you know that facial expressions reveal more than meets the eye? 🤯

Our new study shows that even a mouse's face 🐭 can reflect hidden neural computations🧠. Turns out, facial expressions are more than just emotions!

We're so excited to see this paper out @natneuro.nature.com 🎉

Facial expressions in mice reveal latent cognitive variables and their neural correlates
Nature Neuroscience - The face reveals more than just emotion. Cazettes, Reato and colleagues show that subtle facial movements reveal hidden cognitive states, reflecting the brain’s ongoing...

Interested in doing a Ph.D. to work on building models of the brain/behavior? Consider applying to graduate schools at CU Anschutz:
1. Neuroscience www.cuanschutz.edu/graduate-pro...
2. Bioengineering engineering.ucdenver.edu/bioengineeri...

You could work with several comp neuro PIs, including me.

Easy two part solution.

(a) NIH should run its own journal, in house, that pays reviewers for their time and waives all publication fees for any NIH funded project.

(b) Publication fees for any other journal are then not an allowable budget line on NIH grants.

I still think the major funders should all set up their own PLoS One-style journals (peer reviewed for rigour but not impact) and mandate that if you take their money, you publish the resulting research there, full stop

Please share with anyone who cares about NSF support for graduate students and take 30 seconds to sign and leave a comment.

The deadline for the 2025 Graduate Research Fellowship Program is about one month away and literally no one can apply. #NSFGRFP

I’m super excited to finally put my recent work with @behrenstimb.bsky.social on bioRxiv, where we develop a new mechanistic theory of how PFC structures adaptive behaviour using attractor dynamics in space and time!

I've been waiting some years to make this joke and now it’s real:

I conned somebody into giving me a faculty job!

I’m starting as a W1 Tenure-Track Professor at Goethe University Frankfurt in a week (lol), in the Faculty of CS and Math

and I'm recruiting PhD students 🤗

Schulman thinks Jay isn’t a hardened cynic who is carrying out MAHA marching orders, but an idealist who has naively stumbled into being used as a tool of authoritarianism. He’s just too gosh darn nice & devoted to reason to do this willingly. This view is far too charitable.

A deep dive into the destruction of US cancer research by @jonathanmahler.bsky.social “It’s an absolutely unmitigated disaster,” a former top official at NIH told him. “It will take decades to recover from this, if we ever do.” Gift link: nyti.ms/48iH3Cr

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/

Can a single cell learn? Even without a brain, some microbes show simple forms of cognition. Can this basal cognition be engineered? Check our new paper with @jordiplam.bsky.social on the minimal synthetic circuits & their cognitive limits. @drmichaellevin.bsky.social www.biorxiv.org/content/10.1...
