Abstract:
In static magnetic fields as used in MRT-equipment for clinical diagnosis the "spontaneous" EEG is triggered by each heart activity. The registered signal is characterized by an oscillation of potentials in the frequency range of 8 to 10/s, mostly beginning with the higher frequency. These data sampled are dependent of the magnetic flux vector, but not regularly and independent of the point of lead. These results point to a transition from the isotropic distribution of EEG-currents to an anisotropic state by static magnetic fields.
