The effects of action-based predictions in early visual cortex https://www.biorxiv.org/content/10.1101/2025.08.28.672792v1

Thank you to @bensaunders.bsky.social and Camilla Bellone for the invitation (and patience!) to contribute to this special issue.

We have several empirical papers forthcoming on DA waves, DA regulating mechanisms, and timescales of DA release.

Stay tuned.

Proud of Amy and Nick, who review technical and theoretical gaps in timescales of dopamine fluctuations.

We argue that DA fluctuations are hierarchical control signals, and “tonic” DA relays goal alignment across planning horizons and C-BG hierarchy.

Just gave my lecture at @imbizo.bsky.social summer school today. What an amazing school both in terms of science and social impact --and the place is breathtaking! Now, time to enjoy the summer time with @therealdrdukes.bsky.social, @arifahamid.bsky.social, and all the students and tutors 🏖️

We made it to South Africa safely and this sunset was worth the two red-eye flights to get here 🇿🇦

New results! Led by @jbarbosa.org It's not just that neurons are spiking, it is the geometry of their patterns of spiking.

I wrote a piece for @thetransmitter.bsky.social about why I love participating in experimental summer courses, particularly @nsb-mbl.bsky.social.
