Visual object recognition in humans and nonhu-man primates is achieved by the ventral visual pathway(ventral occipital-temporal cortex,VOTC),which shows a well-documented object domain structure.An on-going question is what type of information is processed in the higher-order VOTC that underlies such observations,with recent evidence suggesting effects of certain visual fea-tures.Combining computational vision models,fMRI experiment using a parametric-modulation approach,and natural image statistics of common objects,we depicted the neural distribution of a comprehensive set of visual features in the VOTC,identifying voxel sensitivities with specific feature sets across geometry/shape,Fourier power,and color.The visual feature combination pattern in the VOTC is significantly explained by their relationships to different types of response-action computation (fight-or-flight,navigation,and manipulation),as derived from behavioral ratings and natural image statistics.These results offer a comprehensive visual feature map in the VOTC and a plausible theoretical explanation as a mapping onto different types of downstream response-action systems.
