How do people reach agreement on public health issues?
Using fMRI hyperscanning + NLP, we found that when conversation partners aimed to compromise rather than persuade, they explored a wider range of mental states and topics — and ended up agreeing more.

Looking forward to reading this - I became a massive fan of @judithholler.bsky.social after her TiCS paper last year

New study out in Neuron: doi.org/10.1016/j.ne.... This work led by Zaid Zada uses fMRI hyperscanning of real dyads to show that speaking and listening rely on shared neural systems; and that conversation recruits unique brain processes that aren't observed in passive comprehension.

Our latest hyperscanning study tracks how neural coupling unfolds during genuine conversation and how it differs from simply reading scripted dialogue: osf.io/preprints/ps...
Excellent new video on our recent work on the neural dynamics supporting good conversations. Check it out - if you speak German.

Pleased to share new work with @sflippl.bsky.social @eberleoliver.bsky.social @thomasmcgee.bsky.social & undergrad interns at Institute for Pure and Applied Mathematics, UCLA.

We will try to answer questions like: How do minds wander in new directions in conversation? How do we negotiate meaning and compromise when our paths diverge? And what happens when one of those minds belongs to a machine? - Please reach out if you're interested or have any questions.
Recruiting PhD students for Fall 2026!
The Coupled Minds Lab at @tamu.bsky.social will use a multimodal approach combining fMRI hyperscanning, computational modeling, and natural language processing to study how conversations transform minds. Learn more: coupled-minds.github.io

Finally, someone has solved a real problem with AI! No more having to take a paper in the format for a journal that rejected you, and reformat it for a new journal. Well done!! formatmypaper.com

just finished steve levinson's new book! it's a beautifully articulated argument for social interaction as the evolutionary niche which made language possible, rather than the other way around. progress in linguistics depends on a stronger science of interaction.

We're a month further into the job market - how are things looking? The good news is that the market does seem to have been delayed: ~150 new listings have appeared since my last post. The bad news is that the total is still substantially lower than what it was during the covid dip.

As our lab started to build encoding 🧠 models, we were trying to figure out best practices in the field. So @neurotaha.bsky.social
built a library to easily compare design choices & model features across datasets!
We hope it will be useful to the community & plan to keep expanding it!

@falklab.bsky.social wrote a nice summary of our hyperscanning work on how people form social connection and find agreement through conversation: www.scientificamerican.com/article/good...

“As AI tools become more capable, funding agencies and institutions may question why labs need dedicated computational staff. But these examples suggest the roles will become more important, not less”
📢Out now! @jixingli.bsky.social, @lamb-cityuhk.bsky.social and colleagues assess whether instruction tuning can enhance LLM's ability to capture linguistic information in the human brain. www.nature.com/articles/s43... #compneuro #ArtificialIntelligence

These are the most challenging times for early-career scientists and engineers.
My team is doing its bit to help by maintaining and even expanding our database of funding opportunities for early-career researchers.
We found 437 of them.

My brilliant labmate, Keith Dodd, created this non-aggressive denoising pipeline for fMRI data for his dissertation! It has been super useful on some of our high-motion datasets, and I highly suggest folks check it out for their own studies 🧠📈🪲:
