Interactive visualization of hippocampal learning: UMAP neural state space alongside Cloned-HMM transition graphs to show how representations orthogonalize across training in VR mouse experiments.
I made a cool visualization of the learning process that happens inside the hippocampus. (Sun et al., 2025)
You can interact with the visualization! Click and drag to rotate. Isn’t it beautiful?
It was one of the key visualizations for today’s symposium at Seoul National University Hospital:
Natural and Artificial Brain Intelligence (NABI) Symposium 2026
