Abstract

The neuroelectric activity that ascends the sciatic nerve and moves to thespinal cord was visualized by measuring the magnetic compound action fields (CAFs) with a superconducting quantum interference device gradiometer. The sciatic nerve of a dog was stimulated electrically, and propagating evoked CAFs were measured non-invasively. Isomagnetic field maps were made on the basis of this data, and the signal propagation was visualized. The evokedmagnetic fields presented a quadrupole consisting of two elements: depolarization and repolarization. Measuring the magnetic CAFs of the sciatic nerve on the body surface enabled us to visualize the non-invasively the signalmovement continuously from the sciatic nerve to the spinal cord.
