Ratios of morphological data for rod microglia.

To further distill the changes observed in microglia morphology post-injury, ratios of the cell length∶width and soma length∶width analyzed. These data indicated that the most dynamic changes were occurring with the microglial processes, which were also analyzed as ratios of number of polar∶planar branches, average and total length of polar∶planar branches.
All significance is time post-injury compared to sham; *p<0.05, ***p<0.001 and ****p<0.0001.
