In this study, using magnetic resonance imaging (MRI), I tracked the developmental patterns of the brain structures during infancy and the juvenile stage in common marmosets, chimpanzees, and humans. Through a comparison of the brain development among three primates, we clarified common features in marmosets, chimpanzee, and humans (primate -shared features), common features in chimpanzees and humans (hominoid-shared features), common features in marmosets and humans (allomothering-shared features), marmoset-specific features, chimpanzee-specific features, and human-specific features.
As main research results of this study, I wrote two peer-reviewed papers (Sakai et al., Neuroscience Research, 2017; Sakai et al., PLOSONE, peer-reviewed), 2 books and conducted the presentations in the meeting and symposiums as 4 invited lectures. Moreover, in 2015, I received the excellent oral presentation award by the 60th Primates Workshop.
