Fig. 9. NdWFamide increases the amplitude of EJP. (A) Effects of 10^–8 mol l^–1 NdWFamide on EJP. Each EJP was evoked by a single nerve stimulation (1 ms, 1.6 V). (B) Comparison of EJPs before (a) and after (b) NdWFamide application. (C) Excitatory action of NdWFamide on EJPs. Histogram shows mean ± S.E. of the maximum amplitude of summated EJPs before and after NdWFamide application (N=9). Statistical significance was assessed by Student's t-test.
