Figure 4.

The greyscale matrices show interaction indices measured at electrode pairs across the electrode array at various electrode separations in sixCI users (seven ears). The scale ranges from white at a 0% interaction to black at a 100% interaction. The measured data points are shown in black outline to distinguish them from the white background. Data for subject S80 and for two CIs in subject S110 (lower row) were collected for electrode separations of three electrodes only. The hatched pattern in (e) indicates that subject S80 had three disabled electrodes at the apex of the electrode array.
