G ratios (axon diameter/fiber diameter) shown as scatterplot against respective axon diameter with linear regression. (a) PBS vs. PYR, the slopes are significantly different between the two groups: PBS, 0.04047 ± 0.001422 (r ²  = 0.5884); PYR, 0.04612 ± 0.001341 (r ²  = 0.6076). Linear regression, p < 0.0038. (b) PBS vs. PYR + NT3, the slopes are significantly different between the two groups: PBS, 0.04047 ± 0.001422 (r ²  = 0.5884); PYR + NT3, 0.05245 ± 0.001944 (r ²  = 0.4464). Linear regression, p < 0.0001
