Clinical electrode impedances (kΩ) 6.00 (2.67) 6.36 (2.60) 4.40 (1.16) 6.45 (2.89)
Longitudinal resistance (kΩ) 0.89 (0.82) 0.79 (0.93) 0.31 (0.13) 0.66 (0.75)
Transverse resistance (kΩ) 23.02 (15.10) 33.74 (29.16) 16.76 (6.07) 15.12 (6.00)

Note. For behavioral threshold measurements, data are averaged across Electrodes 2–8 (apical) and Electrodes 9–15 (basal). For intracochlear resistance measures, data are averaged across Electrodes 1–8 (apical; 2–8 for longitudinal resistance) and 9–16 (basal). EVA = enlarged vestibular aqueduct; DFNB1 = connexin-26 genetic mutation.
