Fig. 4From: Bilirubin potentiates etomidate-induced sedation by enhancing GABA-induced currents after bile duct ligationDose–response curve of rat cortex pyramidal neurons GABAARs currents. A Representative GABAARs peak current traces evoked by 1, 10, 100, 300, 1000 and 2000 μM GABA. B Dose–response curve of GABAARs currents fitted by nonlinear regression with logistic equation. Each data point represents the mean ± SEM (n = 5)Back to article page
