myelination1892

1892 New Sydenham Soc. Lexicon Myelination, the process of development of the medullary sheath, or myelin, of nerves in the embryo; this does not occur in the whole length of some nerves at the same time.

1895 Philos. Trans. 1894 (Royal Soc.) B. 185 740 Bechterew [et al.] have described its myelination as occurring only in the last month of intrauterine life.

1934 Science 20 Apr. 363/1 Vogt..says that myelination of the tracts is not related to the acquisition of conducting power, but to the number and size of the component fibers.

1977 C. S. Raine in P. Morell Myelin i. 9 Myelination in the CNS commences some days after its onset in the PNS.

1984 J. F. Lamb et al. Essent. Physiol. (ed. 2) ii. 32 Myelination confers two advantages on an axon compared to a bare axon of similar diameter.

2002 Amer. Jrnl. Neuroradiol. 23 872 Myelination was evident in numerous gray and white matter structures in the very preterm brain.
