Thank you Rick!

Hope this stimulates the conversation and provides a pathway of how ML research can be applied for monitoring PAs at scale.
Finally we thank the reviewers who encouraged us to test our predictions and you for reading! The double dactyl poem summary didnβt make it past the editor so youβll find it in the preprint β or here. 9/9

And to ΓlΓ©onore Duvelle, @roddy-grieves.bsky.social and @hugospiers.bsky.social who shared another amazing dataset for us to reanalyse. doi.org/10.25493/7NJ... 8/9
17.03.2025 10:48 β π 5 π 0 π¬ 1 π 1If these memories combine reusable codes, these cells should generalise their response when the cheese moves. We find cells like that too: if the cheese moves, the firing field moves accordingly. 7/9
17.03.2025 10:48 β π 3 π 0 π¬ 1 π 0Looks like it is! This cell has a new field in the bottom left after a replay. Thatβs the exact same location of this cellβs spike within the replayed trajectory. If you calculate the ratemap change, it peaks at the replay spike. 6/9
17.03.2025 10:48 β π 3 π 0 π¬ 1 π 0This predicts hippocampal cells that first fire in replay (to encode the new memory) and then obtain a new place field (that reflects the new memory) β we even βpre-registeredβ this in our preprint almost 2 years agoβ¦ www.biorxiv.org/content/10.1... Is that true? 5/9
17.03.2025 10:48 β π 2 π 0 π¬ 1 π 0Or even better: hippocampus encodes those memories in replay. That builds a map for getting to cheese in locations without even going there, so they can be retrieved at that location later. These are memories of the future! 4/9
17.03.2025 10:48 β π 2 π 1 π¬ 2 π 0Crucially, these maps donβt need to be learned from scratch, but can be constructed from reusable grid (βyouβre hereβ) and object-vector (βcheese-over-thereβ) codes. Hippocampus combines them in memory for the current environment. 3/9
17.03.2025 10:48 β π 3 π 0 π¬ 2 π 0If Iβm a mouse that just discovered cheese, Iβd like to know how to return to that cheese later. Instead of learning a plan, we propose building a map that comes with a plan for free. That solves planning in representation instead of computation. 2/9

We propose hippocampus constructs maps from cortical building blocks in replay β now with empirical support! www.nature.com/articles/s41... 1/9
