The Hickman group pioneered a cell-free system to study their development. Contactin-associated protein 2 localizes to these structures and is thought to organize Kv1.1 localization and, along with C-fibers, these sites are where Nav1.6 most frequently localizes. Features located proximal to these structures include lateral loops, transverse bands, and Schmidt-Lantermann cells. The sequestration of the sodium-potassium pump and voltage-gated channels to these sites ensures that little to no loss of membrane depolarization occurs between these sites. When these sites are absent, continuous conduction occurs; in their presence, saltatory conduction occurs. For 10 points, name these neuronal structures that consist of the gaps in myelin sheaths.
