Stimulation with different probes (simulation). (A) Standard probe in Fig. 1. (Top) The hair bundle and the probe geometry. (Middle) Probe displacement along time. (Bottom) Normalized transduction current along time. (B) Thin probe. (C) Thick probe. (D) I-X curves. Line colors correspond to the probe types. (E) Ideally stimulated I-X curve fits perfectly with the first-order Boltzmann equation, while probe-stimulated I-X curves do not (thick probe case shown). For comparison, the displacement of the ideal case was expanded five times and shifted horizontally. To see this figure in color, go online.
