Actually, there is no end-to-end charge transfer, so i believe you would agree with me, there is no electrical current "in the strictest sense of the word" (at least there is definitely no closed circuit). Microcurrents can be observed loccally in the form of moving ions, but this movement is perpendicular to the nerve axon. Look up the term "action potential" and you will understand, i cannot explain this any better without a proper diagram.
