Graphs showing the effect of sequentially higher doses of a etomidate (n = 18) and b propofol (n = 28) on the frequency of seizure-like event frequency. Each dose was perfused for 30 min or until SLE frequency reduced by at least 50 % compared to the baseline value. The data are normalised to the baseline frequency and are expressed as mean + SEM. *p < 0.001, compared to baseline, Friedman Test with Dunn’s Multiple Comparisons
