Abstract :
The detection and multipole current source analysis of the magnetic fields over the lower spine generated by the electric currents in stimulated leg nerves are presented. The measurement of the fields, of the order of 10 fT, was performed inside a magnetically shielded room with a 83 dc-SQUID system developed by the Physikalisch-Technische Bundesanstalt.
