Paired fruit flies synchronize behavior: Uncovering social interactions in Drosophila melanogaster

Behavioral densities across paired and lone contexts.
a) Representative images from each of four steps used to visualize behavioral frequency. In sequence the images describe the progression of time-points on the two-dimensional behavioral space, the Gaussian filtered behavioral density, boundaries for coarse-grained regions based on hand-labeling, and finally the bubble plot summarizing the relative densities and transitions between coarse behavior regions. The size of each bubble represents the relative amount of time spent in that behavior and black lines show the transition probabilities between behaviors with line thicknesses proportional to the probability and right-handed curvature representing the direction of transition. b) Coarse behavioral densities for each of the six categories of experiment. c) We compare the densities across the six conditions by visualizing the JS divergence (Eq 1) across all groups, ordering the rows and columns based on similarity. d) Manually assigned labels describe the eight broad categories of behavior exhibited during the behavioral movies with color and location corresponding to the circle density plots.
