Effects of a partial AMPA receptor antagonist γ-DGG on CF-EPSCs. The graph shows concentration–inhibition curves for wt (white circles), tg(gray diamonds), andtg^rol (black triangles). The ordinate in the graph indicates percentage of the control CF-EPSC amplitude after application of γ-DGG. Values are presented as mean ± SEM from three to five measurements. The curves were fit by the Hill's equation. The half inhibitory concentrations were 3.94 ± 0.36 mm in wt, 4.98 ± 2.26 mm in tg, and 4.80 ± 0.43 mm intg^rol .
