Abstract: The actin filaments are components of the cytoskeleton strongly charged wich are situated in a strongly ionic place. The counterionic cloud about an actin filament can be a highly conductive medium. One experience realized in 1993 shows that it is possible to transmit ionic signals along the filament. A model of this phenomenon proposed in 2004 considers the filament of actin as a transmission line for the ionic current. Each actin monomer is assimilated to an electric element with capacitive, inductive and resistive properties. This model has been based in a relation of the nonlinear capacitance with the charge variation about one monomer and the electrical potential, wich does not have to date a justification. In this talk, we will present a possible way to justify this relation.
