The pharmacological test of Glu-induced [Ca²⁺]_i increases. a Treatment of Ca²⁺ agonists (LaCl₃ and GdCl₃) and GLR-specific antagonists (CNQX and DNQX) reduced Glu-induced [Ca²⁺]_i increases. The relationship between luminescence intensity and the pseudocolor images are scaled by a pseudocolor bar and the numbers next to the pseudocolor bar are maximum and minimum values of luminescence intensity. b The effects of different concentrations of Ca²⁺ agonists and GLR-specific antagonists in Glu-induced [Ca²⁺]_i increases. The results were obtained from at least three independent experiments (mean ± sd; n = 10; NS, not significant P > 0.05; Student’s t-test)
