Abstract:
:Cynomolgus monkey (Macaca fascicularis) is a popular laboratory primate belonging to Old World monkeys, which are the group most closely related to humans except for the apes. This paper summarizes a series of our studies regarding the development of cerebral sulci and gyri in this primate, and the stated possibility of evaluation of the sulcal development for assessing the developmental toxicity testing. The cerebrum of cynomolgus monkeys experienced a regular sequence of emergence of sulci and gyri on gross observation while such timetables corresponded to those obtained by magnetic resonance imaging (MRI) with a lag time of 10-30 days. When the timetables for the emergence of anatomically identical primary sulci and gyri were compared between cynomolgus monkeys and humans, their chronological sequences were comparable, while some sulci and gyri located on the phylogenetically newer cortical region in humans emerged earlier in monkeys. The present paper further indicates brief procedures for evaluating cerebral abnormalities and/or maturity using brain specimens without MRI measurements. The primary sulcal lengths measured by the 'cotton thread' method were a brief index of the degree of regional gyrification. As the development of a calcarine sulcus was closely correlated with morphological maturation of the lateral ventricle, which changed drastically during embryonic days (EDs) 90-100, the cerebral maturity on ED 100 could be evaluated by the infolding of that sulcus. Thus, the present paper provides gross anatomical and MRI references and brief procedures for investigating the normality of the development of cerebral sulci and gyri of laboratory primates, cynomolgus monkeys.
