Fig. 7. Isoflurane augments the muscimol-induced γ-aminobutyric acid current. ( A ) Muscimol (5 μm)-induced outward currents before ( left ) and during ( right ) application of isoflurane. The membrane potential was clamped at 0 mV. ( B ) Amplitude of the current under the action of isoflurane relative to that in the control (n = 8). * P < 0.05.
