Pharmacological agents identify the nAChR subtypes that trigger PSCs. Agonist-evoked PSCs under different conditions were quantitated using charge analysis. The values obtained before perfusion of the neurons with the antagonists were taken as 100%. The data are mean ± SE calculated from three experiments. The values in the antagonist group were significantly different from control (p ≤ 0.02 according to the Student’st test). Note that the bar representing choline-induced PSCs in the presence of MLA is not visible because of a complete blocking effect.
