How prior experience biases new learning for generalization? new preprint is out:
1) behavioral and hippocampal generalization co-emerged in a novel context.
2) BTSP was involved in forming cross-context stable representations, as well as aligning novel neural dynamics to familiar subspace.

It's officially published!! In my main postdoc work with @markplitt.bsky.social and @lgiocomo.bsky.social, we found that the hippocampus simultaneously encodes an animal's spatial position and its experience relative to reward in parallel population codes. 🧵

A flexible hippocampal population code for experience relative to reward - Nature Neuroscience
Sosa et al. find that hippocampal neural activity in mice encodes both environmental location and experience relative to rewards, spanning distances far from reward, through parallel and flexible popu...
