New preprint! 🎉 We investigate how the brain maintains multiple items in working memory, testing two competing hypotheses for sequential memory: neural subspaces vs. neural sequences.

Neural Subspaces Encode Sequential Working Memory, but Neural Sequences Do Not
The neural mechanisms of multiple-item working memory are not well understood. In the current study, we address two competing hypotheses about the neural basis of sequential working memory: neural sub...

To celebrate the closing of our inaugural conference, we have asked our friends at Slowburn Brewing Co-op to help commemorate this event. Together we have come up with the EurIPA – The Last Session, a lovely session IPA🍻

The best scientific papers are provocations, not results you can rely on. Discuss!
What I mean is that they should try to force progress by making an outrageous statement that the established field wants to be wrong, but do it so well that proving it wrong is a real challenge.

When we communicate science, we often don't say where the resources for it come from. This is clearly a mistake: people consuming science should know who is funding it--and if that funding is being taken away. So, I decided to document the funding sources of every scientist mentioned in my book.
