Individual subject impedance values per electrode and NRT threshold are plotted over time. A-F represent individual data for the non-stimulated subjects and G-L for the stimulated subjects. Day 0 represents impedance values obtained immediately prior to implantation. NRT threshold values (red) are scaled to the right sided y-axis. Impedance values are in grayscale and scaled to the left sided y-axis. The most basal electrode (E1) is black, middle electrode (E2) dark gray and most apical electrode (E3) light gray. Impedance levels of 125 kOhms represent the measurement limit of the system.</p
