Inhibition of GABAρ1 responses by quercetin: (a) representative traces illustrating the effect of increasing concentrations of quercetin on GABAρ1 currents elicited by 1 μM GABA. (b) Dose–response curves for GABA in the presence of 10 and 30 μM quercetin. Response amplitudes were expressed as fraction of 30 μM GABA-evoked currents. (c) Current–voltage relationship of 1 μM GABA-evoked responses with or without 10 μM quercetin. The holding potential (Vh) ranged from −120 to +40 mV.
