Effect of ketamine on PPF. A, Ketamine significantly increased PPF of the p10 component at 30 and 60 min after injection (n = 9). B, Enhancement of PPF correlated with ketamine-induced depression at the highest stimulation intensity (800 μA). Representative PPF at baseline (BL) and 60 min after injection of ketamine are shown in C. *p < 0.05 and **p < 0.01 indicate a significant difference with respect to baseline. Values are expressed as the mean ± SEM percentage change with respect to baseline.
