A freeze-etch study of the central myelin.
The intramembranous organization of the interparanodal myelin lamellae in CNS was investigated by means of the freeze-etching technique. The density of the IMPs is about equal on both P- and E-fracture faces of every myelin sheath but varies between the myelin sheaths. The morphology of the myelin tight junctions was also described. The nature of the IMPs and the functional significance of their mode of distribution were discussed.
