The effect of sevoflurane before ⊖-burst stimulation (TBS) on the field excitatory postsynaptic potential (fEPSP) during TBS. Each burst consists of four stimuli at a frequency of 100 Hz; there are 20 bursts per stimulus train; stimulus burst number is indicated on the abscissa. All values are normalized to the fEPSP in response to the first stimulus in the first burst (mean ± SD). Sevoflurane is present for 20 min and removed 10 min before TBS. A two-way ANOVA comparing the no sevoflurane and the sevoflurane before TBS groups found no significant treatment effect of sevoflurane on the fEPSP responses during TBS. TBS maintained a robust response throughout the stimulus period and showed no tetanic depression.
