Before revision:  Myelin is considered a quasi-crystalline material due to limitations of the available standard techniques that do not allow to solve heterogeneity and fluctuations in matter at nanoscale and mesoscale .
After revision:  Myelin is considered a liquid-crystal but information are confined to its average structure due to limitations of the available standard techniques that do not allow to solve heterogeneity and fluctuations in matter at nanoscale and mesoscale .
