Finally, our findings shed lights on neuronal mechanisms underlying fMRI adaptation and representational similarity effects (see supplemental for a simplified simulation).

We also found that cue-specific and cue-independent spatial representations were anatomically separable, indicating different populations of neural units for sensory information processing and memory storage, a hypothesis that requires further rigorous testing.

Furthermore, while cue-specific spatial representations were stimulus-driven, cue-independent ones overall reflected behavior.

Repetition Suppression Reveals Cue-Specific Spatial Representations for Landmarks and Self-Motion Cues in the Human Retrosplenial Cortex The efficient use of various spatial cues within a setting is crucial for successful navigation. Two fundamental forms of spatial navigation, landmark-based and self-motion-based, engage distinct cogn...

Combined with our previous finding of adaptation-based cue-specific spatial representations in the same structure using the same dataset, our study demonstrates for the first time the coexistence of cue-specific and cue-independent spatial representations in RSC.

Representational Similarity Analysis Reveals Cue-independent Spatial Representations for Landmarks and Self-motion Cues in Human Retrosplenial Cortex Abstract. It is a fundamental question in the spatial navigation literature how different spatial cues are unified to form a coherent spatial map of the space. Landmarks and self-motion cues are two m...

How does the brain unify various spatial cues to form coherent spatial representations? Our latest paper shows that RSC contains cue-independent spatial representations in terms of representational similarity during spatial navigation. #7tmri #WolbersLab
