Figure 7: A cross-sectional view of the growing AOT myelin figure in the presence of 2 wt% p-toluenesulfonic acid solution as bilayer penetrating agent, accelerating voltage of 5 kV was used. The surface of the specimen was treated by a vacuum deposition of gold. (a) A cross-section of several AOT myelin figures with single- and multiple-core axons shown by arrows are observed. (b) The internal structures of AOT single-myelin figure revealing the three concentric lipid bilayers with three axons indicated by arrows. The white bar in the micrograph represents 10 μm.
