To investigate the resting potential of snail nerve cells subjected to non-thermic effects of weak, high-frequency, low pulsed frequency magnetic fields. A method was developed in order to determine the bioelectric parameters in the magnetic field of a cavity resonator.

Chamber | The electric field strength at the exposure site was always zero. The object was aligned such that the RF field and the geomagnetic field would flow through the nerve cells in the same direction. |
Setup | The ganglion was fixed in the Ringer solution by cactus thorns instead of metal pins. |

No significant differences between the average value of the resting potentials in the run up and run down occur either as a result of various intensities and modulations or from the duration of the treatment. The flux densities used were not strong enough to produce a measurable influence on the resting potential.
