Amplitude of each evoked potentials. A; VEP, B; SEP, C; ABR. There was no significant difference between Ag/AgCl (left) and MWCNT electrode (right). N = 30 each. D: The impedance of Ag/AgCl (left) and MWCNT (right) electrodes. The impedance of metal electrodes was significantly lower (P < 0.05). The difference in the impedance between electrodes from the two companies was very small. The impedance was 5 kΩ or lower (N = 60 each).
