Multichannel measurements of magnetic compound action fields of the median nerve in man.
Magnetic compound action fields (CAFs) evoked by electrical stimulation of the median nerve at the wrist were recorded with 7-channel 2nd-order SQUID gradiometers. CAFs measured over the elbow and upper arm were biphasic with field patterns and polarities corresponding to the depolarization and repolarization fronts of the action potential volley.
