What does it take to show the brain represents something? We offer a framework that brings conceptual clarity to representation, systematizing how decoding, encoding, RSA, etc. bear on that question. This makes explicit what findings establish and where interpretations go too far.
Terrific work led by @emmaroscow.bsky.social showing that hippocampal replay reflects events with large prediction errors, all the better to bootstrap learning as we slumber

Excited to share our study on the Efficacy and Safety of Psilocybin in Treatment-Resistant Depression (EPISODE) - now published in @jamapsychiatry.com
A negative effect on primary outcome, but evidence for a relevant antidepressant effect of 25 mg psilocybin with psychotherapy in TRD.
It is unclear which aspects of experience shape sleep’s contributions to learning. Here, by combining neural recordings in rats with reinforcement learning, the authors show that reward-prediction sig...
Thanks to everybody who participated! It was fun discussing habits from so many different perspectives!
In beautiful Heidelberg today and tomorrow at #PUG2026! 🌞 If you are interested in Habits in Psychopathology, come to our symposium tomorrow at 4pm, lecture hall 15! I‘ll be talking about successor representation use in high-risk drinking and alcohol-related contexts.
