functional ends such as the distribution of glial metabolites [16,23]. In intimate relationship with the unmyelinated segments or NORs, the myelin sheath enables action potential regeneration and propagation along fibers of varying lengths, resulting in saltatory conduction, an energy-, space- and tim...

A large deletion of the MBP gene in shiverer mutant mice results in the loss of the major dense line, providing direct evidence that the main function of MBP is in myelin compaction and adhesion of the cytoplasmic faces of the myelin sheath. MBP binds to negatively charged lipids on the ...
Myelin is an insulating sheath surrounding axons that facilitates efficient transmission of neuronal impulses. Many neurological disorders are associated with damage to or loss of myelin or errors in myelin development. Noninvasive visualization of myeli

Together, this suggests a largely homeostatic replacement of sheath numbers after single-cell demyelination. Notably, while on average the internodes that were formed after cortical remyelination were shorter than the pre-existing ones (Fig. 2e), they were longer than the new internodes formed by...
