2, the measured action current associated with propagating signal, I, was about 2 [micro]A.
Human median nerve.--The first intraoperative recording of the action current of the human median nerve bundle was reported by Wikswo et al.
From this analysis, we have achieved our original goal of computing the maximum value of the magnetic field produced by the action currents near the surface of the heart, 14 nT, which is significantly larger than any magnetic field produced by neuronal activation.

A model for compound action potentials and currents in a nerve bundle III: A comparison of the conduction velocity distributions calculated from compound
action currents and potentials.
Therefore, the second objective is to introduce a new method of predicting the Conduction Velocity Distributions of nerve bundles from the Compound
Action Currents that are measured magnetically using toroids.
In fact, action potentials (also known as negative variations,
action currents, and death currents) were so well studied in characean cells by Blinks (1936), Osterhaut (1931), and Osterhaut's colleagues at the Rockefeller Institute, that Cole and his colleagues at the National Institutes of Health began studying excitability in characean cells.
