Figure 3

Quantitative characteristics of the CC myelin sheaths. The inner and outer diameter was measured as depicted in Figure 1B. (A) There was no significant difference in inner, i.e. axonal, diameter (p = 0.21). Each dot represents the mean diameter in one animal. Mean and SD is denoted by a horizontal line and whiskers, respectively. (B) There was a significant difference between the groups in outer diameter (p = 0.040). (C) In correspondence with this, there was also a significant difference in the myelin sheath thickness (p = 0.0039). (D) There was no change in g-ratio (inner diameter/outer diameter) between the groups (p = 0.39).
