A Model of Place Field Reorganization During Reward Maximization

MG Kumar, B Bordelon, JA Zavatone-Veth, C Pehlevan - bioRxiv, 2024 - biorxiv.org
When rodents learn to navigate in a novel environment, a high density of place fields
emerges at reward locations, fields elongate against the trajectory, and individual fields …

Single field evolution rule governs the dynamics of representational drift in mouse hippocampal dorsal CA1 region

mammals, the head-direction (HD) system is an essential component of the brain's …

Deep learning-based location decoding reveals that across-day representational drift is better predicted by rewarded experience than time

K Freud, N Lepora, MW Jones, C O'Donnell - bioRxiv, 2024 - biorxiv.org
Neural representations of space in the hippocampus and related brain areas change over
timescales of days-weeks, even in familiar contexts and when behavior appears stable. It is …
