Fig 3. Synchronization of stretch-Ca dynamics with small amplitude sinusoidal inputs at constant NO.

At higher pressure p_m = 500 Pa, t_Ca = 1 s, and t_mech = 0.24 s with input amplitude of 0.01 and input frequencies of a) 0.3 Hz, b) 0.2 Hz, c) 0.1 Hz and d) 0.05 Hz. The tick marks indicate the beginnings of successive cycles of the sinusoidal input signal. The ratio of output frequency to input frequency is at the right of each panel.
