Accumulated physiological evidence has revealed that V4, an intermediate area of the ventral stream, represents arbitrary object shapes as curvature and its direction. In the present study, we investigated computationally that surface representation in lower visual areas has a crucial role in the construction of the curvature selectivity in V4. Model V4 cells that included surface representation for curvature detection showed good agreements with physiology in single-cell- and population-level behavior, indicating that surface representation in early visual areas is crucial for the construction of curvature selectivity. |
