| Outline of Final Research Achievements |
Landmark points of the brain and cranial morphology were extracted using magnetic resonance imaging (MRI) of the head of 16 human infants and children from 3 to 22 months old, and the changes in size and morphology during development were analyzed. The study revealed that (1) there is a large morphological variation in a specific region of the brain, (2) the skull grows anisotropically in the anterior-posterior and lateral directions, and (3) the relative positional relationship between the brain and the skull landmark points is stable, in the course of development. The possibility that the diversity of brain and skull morphology in development leads to the evolution of the brain was discussed.
