The model predictions for Ca²⁺ current in response to membrane potential shift. The model predictions for Ca²⁺ current amplitude shown as a function of extracellular Ca²⁺ concentration and the initial membrane potential values before the voltage shift was applied. (A) The dependence of Ca²⁺ current amplitude on the transmembrane potential alterations is calculated for different extracellular Ca²⁺ concentrations. (B) The graph shows the Ca²⁺ current amplitude dependence on the initial values of the potential when the depolarising voltage shift was applied. The model shows that the ciliary system properties are reasonably conserved under significant variations of extracellular Ca²⁺ and over a wide range of membrane potential values.
