Simulations of the forward transport mode [GABA]-induced pre-steady-state currents. (A) [GABA]-dependence of the pre-steady-state currents. (B) Voltage-dependence of the steady-state current (I_ss/V_m). (C) Voltage-dependence of the pre-steady-state currents. (D) Effect of extracellular chloride substitution. (E) Effect of the extracellular sodium concentration. For the simulations the conditions were chosen to match the experiments shown in Figs. 5 A, 1 D, 4 B, D, and A of the results, respectively. Unless otherwise indicated, for the simulations, the holding potential was set at −40 mV. Ordinate scale is in electronic units (eu) s⁻¹, where 1 eu = 1.602 × 10⁻¹⁹ C.
