Inhibitory effect of MeCbl on ectopic spontaneous discharges of dorsal root. (a) Time histogram showing that local application of the MeCbl (300 μmol/L) decreased the basal firing rate of dorsal roots. (b) Three traces in right panel show firing patterns before (A), during (B), and wash out (C) the application of MeCbl.
