Ipsilateral CST axon terminal ourgrowth (Protocol 4). A, B. Regional axon density maps plotted using the same color scales from the group mean data for injury only (A) and injury + stimulation (B) show that the combined stimulation promoted axonal outgrowth. Outgrowth was not uniformaly distributed within the ipsilateral gray matter. Calibration: 500 μm. Color scale bars are in arbitrary units and are the same for A and B. C, E. The dorsoventral (C) and mediolateral (E) projections of the 2-D heatmaps. Band represents ± 95% confidence interval. Calibration: 1×10−’4mm axon/pixel. D. Significance map, based on t-statistic values for each pixel. Calibration: 500 μm. F. Total axon length was significantly higher (5.4-fold) in the stimulated group than the non-stimulated control group. Error bars and line are mean ± S.E (n=6 for stimulated; n=6 for control). (*p<0.05, ttest).
