An observation about myelination.
An analysis of the direction of myelination of fibers in the optic tract of a kitten shows that the direction of wrapping of neighboring fibers is not random. Adjacent fibers in contact with the same glial process tend to be wrapped in the same direction. A model for myelination is proposed to account for this observation.
