| Outline of Final Research Achievements |
In this study, we investigated the effect of oxytocin on social development in childhood and adolescence. We measured them for children and adolescents and investigated the association between the relationship between social behavior and the physiological status for children and adolescents. As results, in the study on early childhood, we observed a negative association between age and both attention toward social cues and salivary oxytocin levels. In the study on adolescence, we investigated the relationship between DNA methylation of oxytocin receptor and its impact on the brain structures of atypical developmental children with difficulties in interpersonal relationships. As results, we observed negative correlations of gray matter volume in the frontal cortex with the methylation, and group with difficulties showed significantly reduced the volume than healthy controls. These results suggest that oxytocin dynamics on critical periods play important role for social development.
