Study type: Medical/biological study (experimental study)

Does acute exposure to the electromagnetic field emitted by a mobile phone influence visual evoked potentials? A pilot study. med./bio.

Published in: Cent Eur J Public Health 1998; 6 (4): 288-290

Aim of study (acc. to author)

To search for a potential negative influence on the central nervous system (CNS) of the electromagnetic field emitted by a mobile phone, the authors performed a study of the influence of a single short acute exposure to a GSM mobile phone. Visual evoked potentials examination as an electrophysiological marker of CNS dysfunction was used.

Exposure source
Setup The mobile phone with the antenna pushed in was held in the right hand by the test person while talking into it.
Additional info Each session consisted of 4 VEP (visual evoked potentials) tests in a row with 5 min of exposure between the second and the third test. Each subject was examined twice with or without exposure (randomised) at an interval of about two weeks. The test person was aware whether the mobile phone was on or off.
