Finding Behavioral Motifs in Fly Trajectories

Abstract

Abstract Patterns of locomotor activity of a freely moving organism can help characterize its behavioral phenotypes. To infer behavior from such activity in Drosophila melanogaster, we use a real-time image acquisition system to track the movement of multiple flies in three dimensions. When dealing with fly movement trajectories, we must take into account that similar movement patterns can be expressed in different orientations and speeds. In this ...
