Neonates of Old World monkeys have the longest gestational development phase among comparably sized mammals, and as a consequence, neonatal heads approach the size of the birthing canal. This can lead to cephalo-pelvic limitation, a situation in which the size of the birthing canal presents a physical limit on the size and shape of neonate during parturition. An unexpected labor provided a rare opportunity to map deformations experienced by the neonatal brain during these normal contractions. A deformation field analysis produced a 3-D array of 3-D displacement vectors, showing dramatic regional deformation of the fetal brain during normal labor.
