Delighted to share that I’ve been awarded a European Research Council (ERC) Advanced Grant for #InfantNeuroAI The project will investigate how human infants learn to understand the visual world, by combining awake infant neuroimaging (fMRI and OPM-MEG) with computational models from AI.

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:

Busch et al. use nonlinear neural manifolds to help humans gain rapid control over a noninvasive brain–computer interface, allowing them to learn how to play a video game with real-time fMRI neurofeed...

With so many eyes on Pittsburgh during the NFL Draft this weekend, it feels like a fitting moment to share some personal news — I'm excited to be joining the Department of Psychology at Carnegie Mellon University in Fall 2027!

New preprint led by awesome undergrad Abby Bonno! By probing temporal memory for individual items in a sequence, we uncover a 'representational space' of memories that reflects the structure of encoded experiences and provides insight into how different kinds of structure shape memory. osf.io/t5kyx

New paper alert🚨 www.sciencedirect.com/science/arti... Two takeaways. First, 2- to 4-year-olds can use a process called second-order correlation (SOC) learning -- e.g., A & B go together and B & C go together, then A and C go together -- in a category context to make causal inferences.

Second-order correlation learning in 2- to 4-year-old children, and its underlying mechanism

Second-order correlation learning—or the capacity to infer an indirect relation between features based on separate direct relations—has been studied e…

1/7 Can infants recognise the world around them? 👶🧠 As part of the FOUNDCOG project, we scanned 134 awake infants using fMRI. Published today in Nature Neuroscience, our research reveals 2-month-old infants already possess complex visual representations in VVC that align with DNNs.

Awake infant fMRI offers a rare window into early brain and cognitive development. In a new paper out now in Infancy, we leverage data from hundreds of infant scans from the Saxe and Turk-Browne Labs to reveal what factors drive scanning success — and how future studies can maximize data retention!

Functional Magnetic Resonance Imaging in Awake Infants: Insights From More Than 750 Scanning Sessions

Functional magnetic resonance imaging (fMRI) in awake infants has the potential to reveal how the early developing brain gives rise to cognition and behavior. However, awake infant fMRI poses signifi....

This paper was an awesome collaborative effort of a @fitngin.bsky.social working group. It provides a detailed review of how DNNs can be used to support dev neuro research @lauriebayet.bsky.social and I wrote the network modeling section about how DNNs can be used to test developmental theories 🧵

In a new paper, I delve into these two findings and muse on when prediction might help vs. hurt memory (and discuss why this matters for models of memory and the hippocampus). This is my first solo-author paper, and I had a lot of fun putting these ideas on paper! direct.mit.edu/opmi/article...

How Prediction of the Future Affects Encoding of the Present: Cooperation or Competition?

Abstract. Each day brings new experiences and the opportunity to form new episodic memories. However, our everyday experiences are not isolated episodes; rather, there is significant spatial and tempo...

We can use past experience to make predictions about the future. How do predictions affect our memory for the present? My own work (tinyurl.com/42kyukch) suggests that predictions compete with memory. But other recent work (tinyurl.com/2ekd4wr6) found the opposite--cooperation! What's going on here?

Our new paper is out in @natmed.nature.com 😱! A thread: Can our thoughts and feelings directly affect our physical well-being? Our pre-registered, double-blind RCT investigated this by testing if modulating the brain's reward system could enhance immune responses to vaccination.

🥳 So pleased to share our new publication: www.sciencedirect.com/science/arti...

Really enjoyed chatting with @michaelhobbes.bsky.social for this episode! In addition to being a delight to talk to, Michael was _extremely_ committed to getting the facts right & engaged very earnestly with our feedback. A scientist's dream.

Episode 46: Sapiens It's an ambitious goal to write the entire history of humanity in just 400 pages. It's even more ambitious to do it without reading any research.
