A method for evaluation of the electric potential field of a neuron with time-dependent surface potential

Results of the mathematical simulation of the extracellular electric field of the neuron are presented, yielding the formula describing the time and space dependence of the extracellular potential. The general method of the evaluation of the formulae is presented, which is applicable for any computation of the electric field surrounding a body having time-dependent surface potential. The implementation of the resulting formulae in FORTRAN IV for the special case of neuronal model is presented, including the list of input and output data. The possible applications of the suggested method are studied in concluding discussion.
