| Outline of Final Research Achievements |
The purposes of this study were to examine the relationship of non-visual effects of the light and behavior like morning-type and evening-type to genetic factors. It was implied that person who has the longer endogenous cycle of circadian rhythm showed the tendency of evening-type as well as the greater advanced phase shift by the morning light and the smaller delayed phase shift by the nocturnal light. It was suggested that there was an adaptive response to the morning light to easily keep regular circadian rhythm independent of individual difference in endogenous circadian cycle. It was also demonstrated that there was a significant relationship between SNP located on gene locus of LPIN1 and melatonin secretion during nocturnal light exposure.
