Preliminary results of experimental cerebral computed tomography densitometric studies in newborn primates (baboon) indicate that (a) at birth the white matter of the frontal lobe is hypodense compared to the white matter of the parietal and occipital areas, (b) the white matter becomes increasingly dense with age, and (c) at 1 year of age the white matter in the frontal, parietal, and occipital areas of the brain becomes nearly equal in density. The ongoing myelinization process is considered to be one of the critical factors in these developmental changes.
新生灵长类动物（狒狒）脑计算机断层扫描密度测定研究的初步结果表明：（a）出生时，额叶白质与顶叶和枕叶白质相比密度较低；（b）白质密度随年龄增长而增加；（c）1岁时，脑额叶、顶叶和枕叶白质密度几乎相等。正在进行的髓鞘形成过程被认为是这些发育变化的关键因素之一。
