Previous work has suggested that object and place processing are neuroanatomically dissociated in ventral visual areas under conditions of passive viewing. It also been shown the hippocampus parahippocampal gyrus mediate integration objects with background scenes functional imaging studies, but only when encoding or retrieval processes have directed toward relevant stimuli. Using magnetic resonance adaptation, we demonstrated object, scene, contextual selectively repeated could be during viewing naturalistic pictures involving object-scene pairings. Specifically, bilateral fusiform showed adaptation to repetition, regardless whether associated scene was novel repeated, suggesting sensitivity processing. Bilateral regions focal selectivity for Finally, distinct from those involved right unique pairing these perform binding operations.
