Fig. 8. GSPRFFamide decreases the amplitude of EJPs. (A) Effects of 10^–7 mol l^–1 GSPRFFamide. EJPs were evoked by the stimulus train (1 ms, 1.6 V, 10 Hz) for 0.5 s every 20 s. (B) Comparison of EJPs before (a) and after (b) GSPRFFamide application. (C) Inhibitory action of GSPRFFamide on EJPs. Histogram shows mean ± S.E. of the maximum amplitude of summated EJPs before and after GSPRFFamide application (N=14). Statistical significance was assessed by Student's t-test.
