Shearing Explains Grid Asymmetries (IMAGE) Norwegian University of Science and Technology Caption When a fake grid pattern is subjected to shear forces along a wall, both deformation and rotation result, exactly as seen in the recorded grids. Right panels show the effect on a square grid, middle and left panels on a hexagonal grid pattern. Both the orientation of the grid axes and the ellipse that arises from the deformation are shown with black lines.
