Abstract. This article investigates own electrostatic potential of rest in a model neural membrane. It has been shown that even in the case of the molecular structure of the internal and external lipid bilayer of the membrane being absolutely identical, the potential of rest is different from zero. The trans-membrane asymmetry of the membrane is responsible for difference in electric dipoles of phospholipids of the internal and external layer which results in existence of own membrane potential considerable in value ? = -48 mV. It has been shown that optical multi-phonon oscillations of the membrane with wave vector k " 0 can be generated as a result of transforming local oscillations with k = 2?/a - 10?/a, caused by synapses and other types of excitation. Multi-phonon optical oscillation with k = 0 can cause phase transition of the membrane and serve as a trigger mechanism which changes permeability of the passive and active channels of the membrane.
Key words and phrases: потенциал покоя нейрона, мембрана клетки, фазовый переход, оптические фононы, проницаемость мембраны, neuron rest potential, cell membrane, phase transition, optical phonons, permeability of membrane
