Incisure of myelin

WebBy measuring the myelin thickness and axon diameter, the value of g ratio is determined to be 0.68 with forward- and 0.63 with epi-detected CARS. Detailed structures of the node of Ranvier and Schmidt-Lanterman incisure are resolved. We have also visualized the ordering of water molecules between adjacent bilayers inside the myelin. WebThe development of Schmidt-Lanterman incisures was investigated in the rat sural nerve during an active phase of postnatal myelination (5-21 days post partum). Two distinct populations of incisures were recognised and the following nomenclature for their developmental stages is proposed.
