DA activates γ subunit-containing recombinant GABA_ARs. A, Traces (left) and quantitative analysis (right; mean ± SEM) of currents evoked by DA alone (1 mm, filled bar) in untransfected neurons or transfected HEK293 cells. **p < 0.01, ***p < 0.001. B–D, Traces depicting concentration–response curves for DA (0.1–10 mm, filled bars) and supramaximal GABA (0.1 mm, unfilled bar) according to transfected subtype. E, Mean ± SEM for DA-evoked amplitudes compared with GABA amplitudes in individual cells.
