Variability of C. elegans feeding. (A) Cumulative number of pumping events over 30 min (${\text{OD}}_{600}$ = 0 and 4, blue and red, respectively). Individual lines are from individual animals. (B) Example of deviations from the local mean pumping rate as calculated by subtracting a local linear trend with a width of 1 min from the data shown in A. (C) Cumulative pumping events as obtained from simulations with standard parameters at 10 and 30 bpp mean food levels, blue and red, respectively. Each condition was simulated 10 times and is shown as individual lines. (D) Example of deviations from the local mean pumping rate, similar to B, but for simulated trajectories. Each time step in the stimulation represents 1/6 s.
