There is no evidence of an endogenous agonist mediating the tonic current. A. Replacing the sodium in the external bath solution had no measurable effect on the amplitude of the tonic current suggesting that reverse transport of GABA does not contribute to the current (n= 8). B. Similarly, the amplitude of the tonic current is not reduced by rapid solution flow nor increased by stopping flow, suggesting that the current is not mediated by tonic release of agonist (n= 11). Shown are three traces from a single neuron with the baselines of the second and third traces shifted for clarity. During each trace the cell was exposed to three solution flows as shown. Vm was −20 mV with a cesium methanesulfonate pipette solution.
