Brain Neural Mechanisms when Objects are Masked in Scenes

This project investigated the brain neural mechanisms in human scene categorization when the “signature objects” were masked. We collected functional magnetic resonance imaging (fMRI) data of subjects doing a scene categorization task when signature objects were visible or masked, and conducted statistical analyses to investigate the changes in neural activations, functional connectivities, and activation patterns. The results reveal the role of object and scene-selective regions, especially the top-down modulation effect from the fronto-parietal regions in object-based scene categorization.
