[Static NMR magnetic fields change somatosensory evoked potentials in the human].

In strong static magnetic fields as used by NMR for clinical diagnosis we found oscillations in somatosensory evoked potentials of man when stimulating the Nervus medianus at the wrist joint. These new signals are to register only, when the head of the test person is inside of the magnetic field. A magnetic influence only of the stimulated arm has no effect of the normal SEP-signal.
