The Hippocampal Cognitive Map: One Space or Many?

Published on January 21, 2020

New evidence reported by Solomon et al. that hippocampal activity tracks distance in semantic space during recall supports the growing consensus of a domain-general cognitive map. Nevertheless, are all inputs equally processed into a ‘universal map’, or are there input constraints (e.g., space, semantics) that lead to differentiated multiple maps across the hippocampus that have distinct properties?
