New study by @xrmasiso.bsky.social et al shows that spatial contexts with more reliable brain representations better support memory for future experiences within them, revealing how stable neural maps help the brain organize and recall life events.

Another new paper from the lab: Predictive theories like the SR imply that navigators who navigate differently should have cognitive maps which differ in predictable ways. Here we show that this holds in mouse hippocampal CA1.

Environmental representations in mouse hippocampal CA1 reflect the predictive structure of navigation
Predictive theories of cognitive mapping propose that these representations encode the predictive relationships among contents as experienced by the n…

I wrote a thing on episodic memory and systems consolidation. I hope you all enjoy it and/or find it interesting.

A neural state space for episodic memories
Episodic memories are highly dynamic and change in nonlinear ways over time. This dynamism is not captured by existing systems consolidation theories …

Our new paper, “A neural compass in the human brain during naturalistic human navigation” is out in @sfnjournals.bsky.social! First-author @zhenganglu.bsky.social led the charge, with Josh Julian and collaborator @gkaguirre.com.

I've been building a model of how intrusive thoughts can warp cognitive maps (world model) in PTSD & derail goal-directed behavior. It combines successor representation & prioritized replay. I started off with a grid world, then embeddings. Today in a story recall task, reading the text was moving:
