Note Y- and X-axes differ between panels. Middle panel—Scatterplot showing the distribution of ICI (ms) per click train and their minICI (ms) in red, emitted during feeding behavior and social interaction. Lower panel—Scatterplot showing the distribution of ICIir (ms) per click train, emitted during feeding behavior and social interaction.
