This took until last week to finish, but the results are in. In a tense final (commentated by @yarrowdunham.bsky.social), @jinke.bsky.social took home the grand prize, followed by @julia-a-leonard.bsky.social in second and Stefan Lunis in third place. These three are really good at Connect 4.

Our paper is now out in @nathumbehav.nature.com! By periodically probing ongoing thoughts during resting-state fMRI, we found that these rich and idiosyncratic thoughts can be decoded from brain network dynamics and help explain links between functional brain architecture and everyday behavior.

We’re recruiting a full-time lab manager to join the Shared Minds Lab at USC! This will be a great opportunity for someone who wants to get hands-on experience with research before starting a PhD program in psychology or neuroscience. More below:

Preprint alert! 🧠 Using movie-watching fMRI and NLP, we show that prior social impressions shape how new social information is processed and updated over time, while moments of sudden insight ("aha"!) accompany transient shifts in brain activity that predict impression updates. (1/10)

Deeply honored that our paper was recognized with the #SANS2026 Award! SANS was an important part of this paper's journey! @jadynpark.bsky.social first presented this work at SANS2023, and again in SANS2025, and we benefited greatly from the feedback and discussion!

Out now in @nathumbehav.nature.com! We applied graph theoretic analyses to fMRI data of participants watching movies/listening to stories. Integration across large-scale functional networks mediates arousal-dependent enhancement of narrative memories. Open access link: rdcu.be/eKKAw

How does the brain🧠 make causal inferences and use memories to understand narratives🎬? We built an RNN🤖 with key-value episodic memory that learns causal relationships between events and retrieves memories like humans do! Preprint www.biorxiv.org/content/10.1... w/ @qlu.bsky.social, Tan Nguyen &👇

New preprint! 🧠 Our mind wanders at rest. By periodically probing ongoing thoughts during resting-state fMRI, we show these thoughts are reflected in brain network dynamics and contribute to pervasive links between functional brain architecture and everyday behavior (1/10). doi.org/10.1101/2025...

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...

I’m thrilled to announce that I will start as a presidential assistant professor in Neuroscience at the City U of Hong Kong in Jan 2026! I have RA, PhD, and postdoc positions available! Come work with me on neural network models + experiments on human memory! RT appreciated! (1/5)

Feeling fortunate that #SANS2025 was in Chicago, and so much of the lab was able to be part of the meeting! It's crazy how much the lab has grown over the past 3y10m, and I'm so proud of the work we are doing together! Happy that we could host the lab, alums (and surprise guests)! #CASNL@SANS

Curious how the human brain updates social impression in a naturalistic setting? We scanned participants watching This Is Us, and found that sudden neural pattern shifts at insight moments of comprehension reflect impression updating. Come and chat Friday 4:15–5:15pm at #SANS2025, Poster P2-G-69.

Remember what your partner said during a heated argument? Or the rush of getting your first job offer? Why do these emotionally arousing moments stick? Across 3 studies, and 3 arousal measures, we found that emotional arousal enhances memory encoding by promoting functional integration in the 🧠 1/🧵
