Maturation of Normal Primate Cerebral Tissue

Abstract

Cerebral computed tomographic densitometry in newborn primates (baboon) implies that at birth the white matter of the frontal lobe is hypodense compared to the white matter of the parietal and occipital areas, that the white matter becomes increasingly dense with age and that at 1 yr 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 a critical factor in these developmental changes.
