Figure 10.

Comparison of the AP propagation speeds near the last node of Ranvier, near the end of the terminal, and along the length of the entire terminal using both 20 μm ROI and small-circle ROI data (mean + S.D.). There is no significant difference in AP propagation speed in different regions of the terminal (n = 14; p = 0.7515 for 20 μm ROIs, p = 0.3189 for small-circle ROIs; Friedman test), and there is no significant difference between the 20 μm and small-circle ROI measurements in any region (full length: p = 0.5416, node: p = 0.2166, end: p = 0.5830; Wilcoxon matched-pairs signed rank test).
