A Hippocampal–Parietal Network for Reference Frame Coordination

This study shows that during navigation, the parietal cortex (PC) encodes upcoming egocentric actions and conveys them to the hippocampus, which initially encodes allocentric place information but gradually shifts to future goal-directed actions. Bidirectional communication between the PC and hippocampus integrates allocentric, route-centered, and egocentric reference frames to support spatial memory and navigation.
