Lack of effect of somatostatin on voltage-dependent K⁺ currents. A, K⁺ currents in a mass culture neuron were evoked by depolarizations from −80 to 0 mV before (control), during, and after (wash) the application of 1 μmsomatostatin. B, Outward currents in a mass culture neuron were induced by a 0.2 sec ramp depolarization from −70 to +50 mV before, during, and after the application of 1 μmsomatostatin. Note that three traces are superimposed because of the lack of action of somatostatin.
