Fig. 6

Heatmap of strain distribution in the optic nerve (sagittal cross section; distal (closer to the eye) end to the left of the image, proximal (closer to the brain) end to the right), measured as a unitless ratio of tissue length after and before insult. “LE11” represents strain along the radial, i.e., transversal, direction. Warmer colors (positive values) indicate tensile strain, whereas cooler colors (negative values) indicate compressive strain.
