Whether these through-going holes were pre-existing flaws or artifacts of the freeze-fracturing is uncertain.
Now, a comparatively new technique called freeze-fracturing is offering dramatic new clues as to how nerve fibers are organized and what mechanisms may be responsible for producing the neurological changes seen when the myelin sheath surrounding them is damaged.
