Abstract

We have recorded magnetic compound action fields, evoked by median and ulnar nerve stimulation at the wrist, with a 7-channel 1st-order SQUID gradiometer. Responses at cubita, elbow and brachial plexus were usually monophasic, with polarities and field patterns corresponding to the intracellular current flow in the leading edge of the action potential volley.
