Figure 10. Comparison between stiffness of the motor array estimated with step stretches (open squares) and step releases (open triangles).

Filled circles are the same as in Fig. 6D. The lines are the sigmoidal fits (same equation as in Fig. 6D) to filled circles (continuous line, A= 0.87 ± 0.05, k= 2.27 ± 0.15 nm and n= 2.75 ± 0.45) and open triangles (dashed line, A= 1.25 ± 0.18, k= 3.06 ± 0.52 nm and n= 2.07 ± 0.43).
