The text I'm assigning for my course in child psychology (D. Shaffer, 
Developmental Psychology) states that myelinization isn't complete until 
"mid to late teens or early adulthood (p. 171, 4th ed.). He also notes 
that the reticular formation isn't fully myelinated at puberty. His 
reference is J. Tanner (1990), _Fetus into man: Physical growth from 
conception to maturity_, Harvard University Press, which might be a good 
general source for this kind of information.
