How unique and predictable elements of memories are stored and reconstructed by efficiently combining both hippocampal and neocortical systems?

Eleanor Spens, Neil Burgess. A Generative Model of Memory Construction and Consolidation. bioRxiv 2023.01.19.524711; doi: https://doi.org/10.1101/2023.01.19.524711

Abstract
“Human episodic memories are (re)constructed, combining unique features with schema-based predictions, and share neural substrates with imagination. They also show systematic schema-based …
