 I_K-slow and I_K-medium are outward currents elicited by iontophoretic injection Ca²⁺ into acutely isolated nodose neurons of the rabbit. The peak conductance is the largest conductance elicited, independent of membrane potential. The holding potential is the potential at which the peak conductance was measured. The decay time constant was measured by fitting a line, by eye, to the log transform of the decay of the current. The duration was calculated from the onset of Ca²⁺ injection to the time at which the current had decayed to 20% of its peak value. Data are summarized as the mean ± SEM.
