***New preprint from the lab*** showing “Generative replay across hippocampal-neocortical circuits”. In sleep we show spiking sequences in V1 (sensory neocortex!) that represent information that has not been directly experienced www.biorxiv.org/content/10.6... @bndu.ox.ac.uk @ndcnoxford.bsky.social

Generative replay across hippocampal-neocortical circuits
To make flexible decisions, the brain needs to make inferences between events that were not directly experienced together. In sharp-wave ripple (SWR) events, during periods of rest and sleep, spiking ...

Excited to share our #ICML2026 spotlight ✨paper: Hierarchical successor representation for robust transfer. openreview.net/forum?id=txs... We ask a simple question: can an RL agent generalise efficiently under changing goals given its existing knowledge about the environment structure? 1/N

Ever wondered how the hippocampal cognitive map is read-out? @changmin-yu.bsky.social @zilong-ji.bsky.social with Jake & John, show that, during navigation, theta sweeps indicate remembered goal-directions (cf. current/next movements or perceptual targets) 1/2 www.nature.com/articles/s41...
Decoded locations from place cell firing sweep towards a remembered goal location during each theta cycle irrespective of the current movement or head direction
