Medial PFC interacts with the hippocampus to retrieve context-congruent memories.. but HOW?? was what started this. Simulating mPFC-HIP🧠, we designed an RNN🤖 that retrieves memories similar in context, on top of self-attention. It learns to retrieve like humans faster! arxiv.org/abs/2609.37791

🚨 New preprint! With @mdelmarco.bsky.social and @gonzalezgarcia.bsky.social Can episodic memory become more flexible, expanding retrieval to new cues, without sacrificing concrete details? Our results suggest so, highlighting the adaptive nature of episodic memory www.biorxiv.org/content/10.6...

I am very excited to share this. 🧵 www.biorxiv.org/content/10.6... Most of us agree that the HC is critical for associative memory but there is growing work showing it does much more (WM etc.). Recognition partly relies on a global matching, which based on influential models is not supported by HC.

New paper out w/ Katherine Duncan and Morgan Barense! Why do some memories update when our expectations are violated, while others remain stable? What matters most is the strength of a memory at reactivation—not how old it is. And, I designed the cover! royalsocietypublishing.org/rstb/article...
