NEURAL BASES OF SPATIAL FREQUENCY PROCESSING DURING VISUAL SCENE CATEGORIZATION PhD supervision : Carole Peyrin (LPNC) & Alan Chauvin (LPNC)

Keywords : natural scenes ; spatial frequency ; fMRI ; visual cortex

Visual analysis begins with the parallel extraction of different attributes at different spatial frequencies following a predominantly coarse-to-fine default processing sequence. Rapid processing of low spatial frequency information would permit a coarse parsing of the visual input, prior to the detailed analysis of fine information in high spatial frequencies. Our aim was to further address the neural bases of spatial frequency processing during scene categorization. We first demonstrated in two behavioral studies that a coarse-to-fine processing is indeed an advantageous strategy for rapid scene categorization, and is independent of the luminance contrast values associated with the different spatial frequencies. In two fMRI studies, we showed first the involvement of a large cerebral network during coarse-to-fine processing of scenes, including early visual and occipito-temporal areas, but also the inferior frontal cortex. Effective connectivity analysis revealed that the inferior frontal gyrus exerts top-down influence on the early visual cortex as well as on the parahippocampal and fusiform gyri in the occipito-temporal cortex. These results highlight the role of the primary visual cortex in integrating top-down influences from frontal areas to retino-thalamic incoming signals. We also evidenced that the inferior frontal and fusiform gyri actively participate to the integration of the semantic information contained in low and high spatial frequency. Finally, we specifically investigated the spatial frequency processing of scenes within scene-selective areas of the occipito-temporal cortex : the parahippocampal place area (PPA), the retrosplenial cortex, and the occipital place area. We demonstrated that these regions participate differently in the spatial frequency processing of scenes and that a coarse-to-fine processing is favored within the PPA. Overall, results allow us to refine current model of visual scene categorization based on a spatial frequency analysis.
