FIG. 3.
Mode-locking at a drive amplitude of 120 nm. The drive frequency of the top trace is near the low-frequency boundary of the mode-locking interval (from 5 to 8 Hz). The arrow indicates a spike-like event. The bottom trace displays the progression of the mode-locking, with a reduction of the secondary pattern. The scale bar to the left indicates excursion of the hair bundle; the overlaid stimulus trace (black) has been arbitrarily scaled for visibility.
