Fig 6. Quantitative assessment of silver stained images.

Silver stained images were quantified by calculating the percent of region of interest (ROI) in the white matter tract area that was stained with silver. Graphs indicate percent of the ROI showing positive signal in the respective white matter regions. For all graphs, * indicates a significant rTBI effect compared to the respective sham values and # indicates a significant treatment effect between rTBI groups. Data are analyzed by two-way ANOVA followed by a Tukey post-hoc test. For all graphs **: p < 0.01, ***: p < 0.001, ****: p < 0.0001, #: p < 0.05, ##: p < 0.01, ###: p < 0.001.
