Keywords: Gray Matter, fMRI (task based), VASOThe intermediate processing steps in human vision are not well characterised. We show however that the high specificity of VASO fMRI permits investigation functional organisation of curvature responses in human visual area V4, which is an intermediate region in the visual system. Understanding how the functional architecture and hierarchical integration of local contours (curvature) contributes to formation of shapes can inform computational models of object recognition. The emergence of inter-individual differences in these organisations can explain individual differences in healthy and impaired visual perception.
