| Outline of Final Research Achievements |
The present study primarily aimed to investigate the influences of gene x environment interaction on the emergence of ASD-like behavioral tendency during early infancy. To achieve this goal, we carried out longitudinal investigation on large cohort of mother-infant pairs, and collected umbilical cord blood samples and the evaluations of ASD-related behavioral tendencies using gaze tracking and questionnaires. Another aim of the present study was to establish an easily-measurable marker of atypical neural function in developmental disorders. The systematic review of fNIRS (functional near-infrared spectroscopy) studies revealed right-lateralization in atypical neural function in children with ADHD, but no consistent pattern was observed in people with ASD.
