GG muscle EMG activity induced by pulpal application of α⊠β-meATP. A: GG muscle EMG activity induced by pulpal application of α,β-meATP (100 mM). The arrow indicates the timing for drug application. Aa: Onset latency was determined from the time lag between the drug application and onset of EMG activity above 2 SDs. B: Relative area under curve of genioglossus muscle EMG activity induced by pulpal application of α,β-meATP. The data were obtained during 1 min after pulpal application of α,β-meATP (0, 10 and 100 mM). Data were analyzed using one-way ANOVA with repeated measures followed by Bonferroni multiple comparison test (**: P < 0.01).
