| Outline of Final Research Achievements |
Parental daily rhythm has a great influence on that of child, especially during neonatal period. It can lead to a circadian rhythm dysfunction, developmental disorder or psychiatric disorder. In this study, we analyzed the effects of light environment and maternal circadian rhythm on offspring’s circadian rhythm. Circadian clock gene mutant, Clock mouse, was used as a model for a dysfunctional circadian rhythm, and compared with wild type mouse. Light condition optimized for the mutant improve the behavioral rhythm. On the other hand, circadian rhythm in the suprachiasmatic nucleus, the central clock controlling behavioral rhythm, was not improved. Further investigation is needed to reveal a condition which is required to improve the suprachiasmatic circadian rhythm.
