Representative waveforms of voltage-gated K⁺ currents for a control neuron and a CCD neuron. Whole cell K⁺ currents were elicited by a series of 500-ms test pulses ranging from −60 to + 50 mV in 10-mV steps. A and B: neurons were held at −100 mV before each pulse. C and D: neurons were held at −40 mV before each pulse. E and F: transient K⁺ currents were obtained by subtraction currents in C and D from those in A and B, respectively.
