Representations of materials in the human visual cortex(Summary of Awarded Presentation at the 29th Annual Meeting)

抄録

Our ability to recognize surface qualities and infer the materials that make up objects allows us to interact appropriately with the objects. Little is known, however, about the mechanisms of material representation in the brain. In this study, we investigated how information about various materials is processed in the brain using a combination of multivoxel pattern analysis of functional magnetic resonance imaging data and perceptual and image-based physical measures of material properties. We found that information about materials is transformed from image-based representations in early visual areas into perceptual category representations along the ventral pathway.
