Low-angle x-ray diffraction patterns from a variety of myelinated nerves.

Low-angle X-ray diffraction patterns from a variety of myelinated nerves are described. Different kinds of patterns are obtained from peripheral nerve and central nervous system myelin. The intensity variation between the first five diffraction orders is the same for each variety of peripheral nerve myelin, and similarly, an intensity variation exists which is the same for each variety of central nervous system myelin. However, the intensity variation for myelinated nerves from fish is different from peripheral nerve and central nervous system myelin. New diffraction orders higher than five for both peripheral nerve and central nervous system myelin have been recorded.
