... of Biologists Limited 2009 2009 inertia gait Floquet multipliers nonlinear Maintaining a stable walking pattern is a complex motor task since the body's acceleration is constantly changing throughout the gait cycle. For example, during the first half of stance, the center of mass decelerates...

... further enhances gain and frequency selectivity. In both cases, nonlinear properties may maintain the system close to instability,as evidenced by small spontaneous oscillations, while providing a compressive nonlinearity that increases the cell's operating range. Transmitter release also appears...
