Figure 2.

Percentage of rising responses on the apical and the medial electrode pairs (left and right panels, respectively) as a function of ΔF. The results from individual subjects are shown in different panels. The open circles, black squares, and gray diamonds show the data with temporal cues alone, falling place cues, and rising place cues, respectively. Their best-fit sigmoid functions are shown by the solid, dashed, and dashed-dotted curves, respectively. The ΔF values indicated by the arrows corresponded to 76% correct PCI with temporal cues alone and were added to the place-pitch contour stimuli with different amounts of current steering.
