Key ciliary ion channels conductivity dependence on membrane potential. The overall ciliary excitability properties are due to the unique combination of ion channel conductivity dependence on membrane potential. The normalised ion channel conductivities are shown for Ca²⁺ currents v(V), K⁺ currents ${\nu }_{{\mathsf{\text{K}}}^{+}}\left(V\right)$, hyperpolarisation-induced currents v_h(V), and the cilia-to-cell currents v_t(V). The hyperpolarisation and cilia-to-cell currents are activated by membrane hyperpolarisation, whereas the activation of Ca²⁺ and K⁺ channels takes place under depolarised conditions.
