Drosophila is an invertebrate genetic model for studies ofhuman genetically caused diseases. In this study, we proposea new approach to visualize the entire heart chamber,and to observe the retrograde and anterogradebeats. The study is the first to dynamically and noninvasivelyvisualize entire heart chamber. Furthermore, thebeating behaviors from 7-day-old and 21-day-old fliesare compared.
