The first manuscript based on my lab's data! We show that dopamine activity in the ventral striatum encodes moment-by-moment temporal-difference error during aversive situations, suggesting that dopamine can be a unified teaching signal across valences. doi.org/10.1101/2025...

Our work with Pablo Tano, @hyunggoo-kim.bsky.social Athar Malik, Alexandre Pouget and @naoshigeuchida.bsky.social exploring how dopamine neurons could enable multi-timescale reinforcement learning in the brain is out in @nature.com www.nature.com/articles/s41...

🎨 In case anyone need… The NIH BioArt Source is an awesome library of *free* professionally drawn illustrations for scientific presentations or figures. Downloadable in HD. Thank you NIH for this invaluable tool 🙏! Check it out 👇 bioart.niaid.nih.gov

Great to see a big flow of migration to @bsky.app. Hopefully, servers can support unprecedented large traffics!!

Excited to share my first post here! Our new paper reveals a top-down breathing circuit that slows breathing to ease anxiety & fear. A step forward in understanding how brain-breathing interactions shape emotion. Published in Nature Neuroscience—grateful to my team! www.nature.com/articles/s41...

I am recruiting graduate students for my lab @mcgillu.bsky.social for admission in Fall 2025! Get in touch if you're interested in how brain circuits implement distributed computation, including dopamine-based distributed RL and probabilistic representations.
