Topic: spatial topology

Successful goal-directed navigation requires estimating one’s current position in the environment, representing the future goal location, and maintaining a map that preserves the topological relationship between positions. In addition, we often need to implement similar navigational strategies in a continuously changing environment, thereby necessitating certain invariance in the underlying spatial maps. Although previous research has identified spatial maps in the hippocampus and parahippocampal cortices, these maps encode the current position of an animal and is context-dependent, whereby ch
