Figure 5

Optimum chemotaxis performance, measured as in Figure 3A, for the hybrid response with increasing contribution from the linear response ( λ Lin ). The different curves correspond to different total sensitivities (λ Lin + λ Adapt ) as indicated on each curve. The shaded region indicates where the chemotactic ability was within 0.1% of the optimum for a given total sensitivity for a range of values of λ Lin . Note that having an adaptive response component is optimal only above a certain level of system sensitivity, with the optimal contribution of the adaptive response increasing with increasing sensitivity. The red shaded region indicates where the optimal value of β was approximately 100.0.
