🧠 Focused ultrasound changes emotional processing 🔊 In a new study published in Neuron today, we stimulated the human amygdala using transcranial ultrasound stimulation (TUS) and show it plays a causal role in detecting and resolving emotional ambiguity.

Now online in @biologicalpsych.bsky.social CNNI - our paper showing that reliance on habitual responding in transdiagnostic compulsivity may be underpinned by uncertainty about learned environmental structure 📃 www.sciencedirect.com/science/arti...

I'm teaching Statistical Rethinking again starting Jan 2026. This time with live lectures, divided into Beginner and Experienced sections. Will be a lot more work for me, but I hope much better for students. I will record lectures & all will be found at this link: github.com/rmcelreath/s...

We're wrapping up for the year at BRIC, and what a year it was! After a good rest, we will be ready for more wonderful research in 2026. Happy Holidays, everyone!

New study out today in Nature Comms: www.nature.com/articles/s41..., in which we set out to test whether ultrasound could influence the reward-related learning computations of the nucleus accumbens, building on decades of work on dopaminergic prediction error and reinforcement learning. And it did.

I updated a blog which I wrote a few years ago about PhD applications. There's a mix of reflections and practical tips which should be useful for anyone thinking about applying for a PhD (at predominantly UK institutions). Please share if it could be helpful! timothysandhu.github.io/blog/phd_blog/

Please read these two very important letters below in response to a recent case reporting a serious medical event following TUS ⤵️

So great to share plans for my upcoming online study and broader PhD with brilliant minds at my first conference #BAP2025 and fantastic computational modelling workshop #CSC2025! osf.io/7fqbe
