The integrative nature of scene representation

A central question in human visual cognition is how we construct a coherent scene percept, rapidly recognizing scene structure while integrating multiple views that constantly change over time. Past studies have shown that a number of brain regions are involved in scene understanding, including the parahippocampal place area and the retrosplenial cortex. Here I examine the nature of the representations in these networks of scene processing regions, using fMRI multi-voxel pattern analysis and repetition suppression methods. First I show how the brain represents geometric scene properties, such as spatial layout, spatial size and boundary structure. Second, I show how the brain represents functional properties of a scene, such as the functional affordance of a boundary and navigability of a scene. Finally, I show the functional architecture of neural scene representation that supports the integrated scene percept that encompasses multiple views over time. Altogether, my results show how multiple scene processing regions play distinct but complementary roles in constructing the rich and integrated scene representation that underlies our everyday experience of the visual world.
