In the present study developmental changes in the cerebral sulci and volumes of subcortical and archicortical structures of the cerebrum in cynomolgus monkey fetuses were examined with Tj-weighted magnetic resonance (MR) images in 3D. On the embryonic day (ED) 90, the lateral ventricle had still an immature vesicular shape in the occipital region of the cerebrum, and it dramatically closed its lumen by ED 100. In that period the calcarine sulcus progressively infolded from the medial surface of the cerebral hemisphere narrowing the lumen of the lateral ventricle in the occipital region. Volume of the lateral ventricle decreased in the period ED 90-100, increasing afterwards in spite of increasing volumes of subcortical and archicortical structures such as the caudate nucleus, putamen, globus pallidus, amygdala and hippocampal formation. During the same time, the volume of the germinal matrix around lateral ventricles decreased to disappear completely by ED 120. These results suggest that the morphological maturation of lateral ventricle is linked to the development of calcarine sulcus in cynomolgus monkey fetuses. The degree of infolding of calcarine sulcus on ED 100 would be useful as a gross anatomical landmark for evaluating the cerebral maturation in cynomolgus monkey fetuses.
