Drosophila melanogaster grooming possesses syntax with distinct rules at different temporal scales
Fig 3
Binning grooming bouts by duration allows for analysis of temporal dependence.
Ethograms are modified by introducing a binning scheme based on grooming bout duration. Here, we show the binning strategy used to create three duration categories for grooming actions. Grooming actions are classified as short, medium, or long bouts, indicated by the red, green, and blue regions of the probability density functions, respectively. Region boundaries are chosen such that each duration category contains an equivalent number of samples. Notably, anterior motif actions (f, h) possess strikingly similar duration distributions, suggesting coupling between these actions.
