[Visual evoked cortical potentials modified by a NMR magnetic field of 0.24 Tesla].
The visual evoked cortical potentials (VECP) of ten persons with normal vision were investigated under the influence of a nuclear magnetic resonance (NMR) field with a magnetic field strength of 0.24 T. An increase in latency of 2.09 ms for the mean value was found with weak significance and a significant increase of 2.55 ms for the median under magnetic field influence. There were no remaining changes in the VECP after ceasing the magnetic field. The method and results are demonstrated and discussed.
