Appendix 1—figure 28. Calcium-dependent potassium channel dependence on calcium concentration.
(a) The normalized conductance of the channels are plotted as a function of test voltage step and calcium concentration. (b) and (c) The current-voltage relation is shown at several calcium concentrations for (b) KvCaB channel and (c) KCaS channel. Note that the KCaS channel is only active at the highest calcium concentration and is not dependent on voltage (although the voltage continues to set the driving force) when it is active.
