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.

Timescales of dopamine release in the striatum as a window into hierarchical control
The reinforcement learning community has made significant progress in understanding dopamine (DA) in reward learning, cognitive control, and motivatio…

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 🏖️

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