Outline of Final Research Achievements |
In this study, we conducted research on the circadian rhythms using a species of reptile, the Australian dragon. We placed them under constant darkness conditions and recorded their behaviors, as well as sleep-wake cycles. As a result, we discovered that the behaviors and sleep-wake cycles of the dragons exhibit clear circadian rhythms even under constant darkness conditions. Additionally, we prepared brain slice samples and attempted neural activity recordings. This study demonstrates the utility of the Australian dragon in circadian rhythm research.

Academic Significance and Societal Importance of the Research Achievements |
本研究によって、オーストラリアドラゴンの行動および睡眠・覚醒が恒暗条件においても明瞭な概日リズムを示すことを明らかにした。この結果は、オーストラリアドラゴンが概日リズム研究においても有用であることを示す。これは、今後、展開を予定している爬虫類を用いた概日リズム研究の重要な基盤となる。将来的には、種を超えた概日リズム制御機構の解明に寄与し、概日リズム関連疾患の理解や治療法の開発に貢献する可能性がある。
