The new #NSF #GRFP application now excludes 1000’s of students, including those who were told they could apply this year, or who planned to apply next year.

We have a new specific petition urging #NSFGRFP undo this harmful action. If you are impacted sign here: laurenkuehne.github.io/grfpChanges/

Our young lab greatly appreciates open datasets and code provided by pioneers in the field! @alexanderhuth.bsky.social

The GRFP announcement from NSF cuts out an entire cohort of 2nd year students from consideration, without warning. This is so deeply unfair that it warrants a formal protest from the scientific community. If someone wants to work with me to craft an open letter and solicit signatures, LMK.

Here is our best thinking about how to make world models. I would apologize for it being a massive 40-page behemoth, but it's worth reading. arxiv.org/pdf/2509.09737

I am hiring a post doc at UAlberta, affiliated with Amii! We study language processing in the brain using LLMs and neuroimaging. Looking for someone with experience with ideally both neuroimaging and LLMs, or a willingness to learn. Email me with Qs

I love the smell of consequences in the morning. Thank you, @dragoncon.org

In our new paper, we explore how we can build encoding models that are both powerful and understandable. Our model uses an LLM to answer 35 questions about a sentence's content. The answers linearly contribute to our prediction of how the brain will respond to that sentence. 1/6

Many thanks to the volunteer organizers and the flash talk presenters for making the CCN watch party at Georgia Tech a success! And thanks all attendees for coming and engaging in discussions!

Looking forward to #CogSci2025 ! Find us throughout the conference

Atlanta community: we are organizing a CCN @cogcompneuro.bsky.social watch party!

Watch the talks, engage in structured discussions, and (optionally) present your own work.

Georgia Tech’s Neuro Next Initiative has officially evolved into the Institute for Neuroscience, Neurotechnology, and Society (INNS). A new era of interdisciplinary research begins today.

So far we have CCN local meetups @ NYC @neurograce.bsky.social, Boston @lynnkasorensen.bsky.social, Atlanta @neuranna.bsky.social, Lyon and Bucharest!

Who will host one on even further away from Amsterdam (West Coast? East Asia? Africa?)

What are the organizing dimensions of language processing?

We show that voxel responses during comprehension are organized along 2 main axes: processing difficulty & meaning abstractness—revealing an interpretable, topographic representational basis for language processing shared across individuals

A postdoc in my lab contacted a fellow scientist to get some advice and was told that, because he's currently working on the topic, he "can't give away all his secrets." I find this extremely lame, and yet I keep encountering it. Science is not a zero-sum game!!

The anterior temporal lobe (ATL) seems crucial for both semantic memory and semantic composition. How to make sense of this neuroanatomical alignment? 🧠

Very cool work by Qiawen (Ella) Liu, Paridon, @glupyan.bsky.social: e.g., Is white hot or cold?
LMs consider 'white' cold because it's mediated by 'snow'
Ablate the mediators, and you eliminate the associations.

🚨 New Preprint!!

LLMs trained on next-word prediction (NWP) show high alignment with brain recordings. But what drives this alignment—linguistic structure or world knowledge? And how does this alignment evolve during training? Our new paper explores these questions. 👇🧵

Woah!

Multiple brain activation patterns for the same perceptual decision-making task - Nature Communications Here, the authors show the brain uses multiple activation patterns to perform the same task. Even the default mode network, which is often inactive during focus, plays a role.

New paper alert! Have you ever looked at single-trial fMRI activation maps? If so, you know that they are super variable. Here we show that the variability is not just noise. In fact, the same task can consistently elicit different activation patterns. www.nature.com/articles/s41...

Many cognitive neuroscientists ignore the cerebellum but it's long past time to pay more attention to it (and fund more cerebellum grants).

Not just for basic science: the cerebellum is commonly affected by pediatric brain tumors, leading to lifelong motor AND cognitive deficits.
