| Research Abstract |
Activity of animals shows 24 hr rhythmicity called the circadian rhythm. This rhythm is controlled by the function of clock neurons and clock genes expressed in these neurons. The question is that the clock genes and the clock neurons also regulate an emergence of behavior in shorter time scale. By using Drosophila, I shown in this study that the clock genes affect on the emergence of behavior in shorter time scale, such as the locomotion activity or the courtship behavior.
