Abstract:
This protocol describes a simple locomotor assay in Drosophila melanogaster. In brief, the locomotor of each single fly in the culture dish is recorded by a web camera. The moving time, walking length, speed and the locomotor trails of the single fly could be quantitatively analyzed.
Insights
This study details a simple assay to measure fruit fly (Drosophila melanogaster) movement. It allows for quantitative analysis of walking speed, distance, and time, providing insights into locomotor behavior.
