Drift of spatial memory representations in the hippocampus and medial prefrontal cortex
Abstract: The talk will first discuss published work suggesting that place cell representation drift emerges earlier during long (up to 20h) sleep. The rest of the talk will cover unpublished work, showing that during spatial (8-arm maze) learning, representational drift is stronger in the medial prefrontal cortex than in the hippocampus. Finally, work related to brain criticality analysis will be presented that shows a relationship between an information coding-independent network parameter and the animal's ability to learn and recall spatial memories on the cheeseboard.
