[Hysteresis properties of excitable membranes--the basis for neuronal memory]

It is supposed that "fixed" membrane charges are spaced on protein lateral chain terminals and have limited ability to move with the chains. Interactions of the charges that are located on the opposite sides of the membrane depend on the membrane potential and can be described by a hysteresis volt-conformation characteristics with trigger transitions for one stable state to another. The value of the charges, that are shifted in the hysteresical loop limit, is close to the experimental data for gate currents. Possibility of interaction of chemoreceptive and electroexcitable mosaics of the neuron somato-dendrite membrane in eeg forming process is analysed.
