CNAP determination. (a) Set of the 7 Ag/AgCl electrodes, including S (1 pair of stimulating electrodes), G (1 grounding electrode), and R1 and R2 (2 pairs of recording electrodes). is the space between the electrodes of R1 and R2, which were fixed during the whole procedure. (b) A normal sample trace of CNAP without drug exposure. The time points of the onset time, peak to peak amplitude are shown.
