Figure 1From: Statistical structure of lateral connections in the primary visual cortexTopography matching of tree shrew maps. (A) shows a schematic of the topography of the tree shrew. The area shaded grey is a compressed topography of the ipsilateral hemisphere and is excluded from analysis due to its very different magnification factor. To facilitate analysis the maps are rotated to align the vertical axis (B) and then flipped to give a right-handed co-ordinate system (C).Back to article page
