Excited to be at #ohbm2026 @ohbmofficial.bsky.social presenting our real-time fMRI paper just published in @natneuro.nature.com ! come learn more at my talk on Wed at 9am in the symposium on “Closed-loop fMRI Neurofeedback” in Room E

Our new paper is out this week in Nature Neuroscience! www.nature.com/articles/s41... We built a BCI that works with the brain's natural geometry — and we found that people could learn to play a video game with their brains in <1 hr of training. This efficiency is groundbreaking & here's why:

Excited to be in Amsterdam for #CCN2025! Come learn about a project combining many of my favorite interests - naturalistic neuroimaging, development, & manifold learning (of course). Catch me at poster C181 on Fri - “Intrinsic dimensionality of brain activity manifolds across tasks and development”

Preprint⭐ Our attention changes over time and differs across contexts—which is reflected in the brain🧠 Fitting a dynamical systems model to fMRI data, we find that the geometry of neural dynamics along the attractor landscape reflects such changes in attention! www.biorxiv.org/content/10.1...

Geometry of neural dynamics along the cortical attractor landscape reflects changes in attention

The brain is a complex dynamical system whose activity reflects changes in internal states, such as attention. While prior work has shown that large-scale brain activity reflects attention, the mechan...

New preprint!

 tl;dr — We ran around late at night to record wild rats in NYC and figured out how to quantify their behavior and environment. 🧵 w/ Dima Batenkov, @zamakany.bsky.social, Emily Mackevicius www.biorxiv.org/content/10.1...

Computational Urban Ecology of New York City Rats

Urban rats are highly adaptable, thriving in the dynamic and often inhospitable conditions of modern cities. Despite substantial mitigation efforts, they remain an enduring presence in urban environme...

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

New preprint! Excited to share our latest work “Accelerated learning of a noninvasive human brain-computer interface via manifold geometry” ft. outstanding former undergraduate Chandra Fincke, @glajoie.bsky.social, @krishnaswamylab.bsky.social, and @wutsaiyale.bsky.social's Nick Turk-Browne 1/8

Accelerated learning of a noninvasive human brain-computer interface via manifold geometry

Brain-computer interfaces (BCIs) promise to restore and enhance a wide range of human capabilities. However, a barrier to the adoption of BCIs is how long it can take users to learn to control them. W...

Have you wondered where scene perception and memory intersect in the brain? Do you want to localize these areas? In a preprint, @carolinerobertson.bsky.social, Deepa Prasad, Brenda Garcia, and I detail this topography and release these parcels and our localizer. www.biorxiv.org/content/10.1...

Thrilled to share new work w @taylorwwebb.bsky.social Shanka Mondal: A Prefrontal Cortex-inspired Architecture for Planning in Large Language Models (arxiv.org) LLMs struggle w multi-step planning. We propose a solution inspired by brains: planning via recurrent interactions of PFC subregions. 🧵1/n

Resting state, or sleeping state? We know that wakefulness matters for adult functional brain network organization. In our new paper, we show that wakefulness can also be important in infant fMRI! 1/9

Functional networks in the infant brain during sleep and wake states

Abstract. Functional brain networks are assessed differently earlier versus later in development: infants are almost universally scanned asleep, whereas adults

Why do people process language differently from each other? In a new paper, @esfinn.bsky.social and I show that the “concreteness” of word meanings plays a central role in shaping our unique experiences of natural language. Preprint: www.biorxiv.org/content/10.1... Thread below! 1/9
