Boltzmann parameters of activation and inactivation curves for INa and T- and L-type Ca2+ currents.

Effect of exendin-4 treatment on Boltzmann parameters of activation and inactivation curves for INa and T- and L-type Ca2+ current in FNC and SK-N-AS cells. * = pvs. the related control. Ip/Ip, cont and G/Gcont, represent the ratio of the peak currents and conductance in exendin-4 treated cells respect to their corresponding control. Va and Vi are the half-voltages of activation and inactivation, respectively. ka and ki are the steepness factors for the activation and inactivation Boltzmann curve. EXE = exendin-4.
