If it holds, it links how the brain sees scenes with how it remembers places and navigates.","findings":["A ventrolateral 'What' stream reaches the inferior temporal cortex for object and face identity and feeds memory, semantic and emotion systems.","A superior temporal sulcus 'What' stream responds to moving objects, faces and expressions, and connects to the orbitofrontal cortex for emotion and social behaviour.","The dorsal 'Where' pathway to the parietal cortex supports actions in space and also supplies inputs to the parahippocampal scene area for updating locations in scenes during self-motion in the dark or when the view is obscured."],"terms":[{"term":"parahippocampal scene area","means":"A region of the brain near the hippocampus that responds strongly to scenes and places."},{"term":"hippocampal episodic memory system","means":"The hippocampus and connected regions that store memories of specific events and where they happened."},{"term":"landmark-based navigation","means":"Finding one's way by recognising and using fixed features of the environment as reference points."}],"basis":"abstract","abstractFrom":"europepmc","model":"claude-sonnet-5-5","writtenAt":"2026-10-12T10:47:46.219Z","version":"context/0.2"},"summary":{"status":"written","at":"2026-10-12T10:47:46.219Z","attempts":1,"model":"claude-sonnet-5-5","why":null},"note":"Machine-written context to help a reader: it is not evidence, it moves no number, and it may be wrong.
