Resting motor threshold RMT and Motor evoked potentials MEP under wakefulness and anesthesia. A RMT. B MEP C Peak-to-peak amplitude of MEP. Anesthesia increased RMT and decreased the amplitude of MEP. The data were expressed as mean ± standard error of the mean (SEM). *P < 0.05, **P < 0.01. The data satisfies the normality
