[Does a 50-cycle alternating field cause central-nervous effects? (author's transl)].

This project was to provide a further indication for the triggering of central-nervous effects by a 50 - cycle alternating field with a field strength of 5.300 V/m. Previous studies already raised the suspicion of an effector mechanism of this kind: for instance, the nucleus temperature of rats sank under field influence. The same effect is triggered in mice and rats by prescribing centrally stimulating pharmaca. Furthermore, a rise in diastolic blood pressure with a simultaneous drop in heart rate was described for human subjects. We were able to demonstrate the latter effect in laboratory animals (rats). The experiments under consideration resulted in a significant rise in norepinephrine content of the rats' brains following brief exposure of 15 min length. The measured data after 10 d fell highly significantly below those of the untreated controls and remained approximately at this lowered level until the end of field exposure (21 d). Changes in "turn over" of the norepinephrine metabolism of the brain represent an important indicator for the demonstration of the stimulation of central-nervous structures. Our findings therefore substantiate the presented hypothesis of a central-nervous point of attack by electrical energies.
