Fig 2. LI-rTMS does not affect RGC survival or axonal regeneration following optic nerve crush.

A: photomicrograph showing RGCs immunolabelled with β3 tubulin following an optic nerve crush and 2 weeks of daily LI-rTMS. Scale bar is 100 μm. B: Histogram showing counts of surviving RGCs in LI-rTMS and sham stimulated retinas 2 weeks following an optic nerve crush. There was no significant difference between the stimulation groups (p = 0.256). Error bars are standard error of the mean. C, D: GAP-43 immunohistochemistry in the proximal (C) and distal (D) optic nerve did not result in labelling of any axons. The crush site is indicated by *. Scale bar 100 μm
