Abstract
Central myelin is an envelope composed of dozens of superimposed layers of the plasma membrane of oligodendrocytes around the neural axons. This sheath functions as an insulator that increases the efficiency and speed of the electrical impulse. Several traditional staining methods have been available to observe myelin in tissue sections for many years. However, most of what we know about the structure and organization of myelin comes from transmission electron microscopy images. Nowadays, specific molecular components of myelin can be identified and visualized by fluorescence microscopy. Even though, their lipidic nature is much more difficult to observe by this kind of microscopy technique. In the last years, superresolution and other imaging techniques were developed and applied to the study of myelin. Thanks to these and other advances in imaging that are described in this chapter, new structural details as well as many of the fine steps involved in myelination are now visually accessible.
