[Resonance phenomena in membranes containing ion channels with inactivation].
A mathematical model of the ion transport across a membrane containing channel with inactivation has been analysed. Under certain conditions, such a membrane has been shown to behave as a selfoscillating circuit of a very high quality, its own frequency ranging for a variety of natural channels between 10(-1)-10(3) cycles. When exposed to an alternating electric field with a frequency approximating f0, the membrane displays resonance changes in its potential and channel conductivity. The average (over a period of forced oscillations) values of the potential and conductivity also show a resonance type of dependence on the frequency of the external field.
