Proud to share our latest preprint with my very special @mengya-zhang.bsky.social (🥰). Briefly, we studied how the degree to which CA1 responses are the same (reinstatement) or different (novelty response) supports memory, echoing a central tension in the field. 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.
