"The Representational Topography of the Visual System"
The visual system transforms incoming patterns of light into useful representations of the physical world—what are these formats and what pressures govern their formation? My approach starts from the premise that cortical topography—that is, the spatial organization of responses across the cortical surface—is a critical source of information about the format of the underlying representation and the functional roles of brain regions. I will present empirical work that reveals new factors in the large-scale organization of visual brain responses, and complementary computational work which provides new insight into why we have multiple early visual areas, and how the mosaic of category-selective regions are integrated with the surrounding cortex. Broadly, these results depart from the traditional emphasis on specialization and instead drive to an integrated domain-general account of visual representation, advancing new computational modeling approaches to explore the local and long-range architectural constraints that underlie the organization of the visual system.
