Representative data of evoked potentials. Electrodes placed parallel. A: VEP sampled simultaneously with Ag/AgCl (left) and MWCNT electrode (right) in a volunteer. L: left occipital, M middle occipital around confluence, R: right occipital. The quality and signal-to-noise ratio of data obtained with MWCNT electrodes were almost equal to what is obtained using conventional metal electrodes. B: SEP data by Ag/AgCl (left) and MWCNT electrode (right) in a volunteer. C: ABR samples by Ag/AgCl (left) and MWCNT electrode (right).
