The electrotonic interaction between adjacent nerve fibres in the nerve trunks has been mathematically studied. When a nervous impulse runs over several fibres a membrane potential is induced in the adjacent non-excited fibres which at first hyperpolarizes the fibre then depolarizes it and, finally, again hyperpolarizes it. Analytical formulae have been derived which describe this process. It is shown that in certain conditions depolarization may exceed the critical level and the excitation may pass to an adjacent fibre-ephaptic transmission. The dependence of this process on the resistance of the intercellular medium, the radius of the fibre and the capacitance and resistance of the membrane has been analysed.
