[The effects of pulsed low-level EM fields on memory processes].
This pilot study examined the effects of pulsed electromagnetic fields on the organism in humans. Using a psychophysiological test, the changes in memory performance were tested in 33 volunteers both at rest and upon exposure to pulsed fields (GSM standard). To evaluate the cognition performance, we applied a psycho-physiological test paradigm (auditory discrimination task) based on the "Order Threshold". The investigation took place in an acoustically-shielded room, and the volunteers were requested to relax on a stretcher. The exposure to electromagnetic fields took place during this relaxation time (30 minutes). Measurements were performed before and after the exposure phase, and compared to a reference situation of change in vigilance. Exposure to pulsed fields resulted in reduced mental-regeneration performance in 21 of the 33 test participants, as reflected by an increase of order threshold.
