Fig. 7. Effects of dissociative anesthetics on γ-aminobutyric acid^A(GABA^A) and glycine receptors. (A ) Ketamine effects on the current responses of α¹β²γ^2SGABA^Aand α¹glycine receptors to EC^50–60(agonist concentration giving 50–60% of the maximal response) concentrations of GABA and glycine, respectively. (n = 4). (B ) Dizocilpine effects on the current responses of α¹β²γ^2SGABA^Aand α¹glycine receptors to EC^50–60concentrations of GABA and glycine, respectively (n = 4).
