“…Freude et al [1998] found that a 916.2 MHz EMF pulsed at 217 Hz resulted in signi®cant decreases in brain slow potentials, most pronounced in the right hemisphere central and temporal-parietal-occipital areas, but not frontal regions. A further study by Freude et al [2000] using the same exposure conditions con®rmed results of their previous experiment, ®nding decreased event related slow potentials at central and parieto-temporooccipital regions, but not at the frontal regions and without decrement in performance task measures. Krause et al [2000a] found that a 902 MHz EMF pulsed at 217 Hz increased the relative EEG power in the 8±10 Hz (alpha) range, a task speci®c ®eld effect on the retrieval portion of a working memory task.…”

The investigation of weak (<500 microT), extremely low frequency (ELF, 0-300 Hz) magnetic field (MF) exposure upon human cognition and electrophysiology has yielded incomplete and contradictory evidence that MFs interact with human biology. This may be due to the small number of studies undertaken examining ELF MF effects upon the human electroencephalogram (EEG), and the associated analysis of evoked related potentials (ERPs). Relatively few studies have examined how MF exposure may affect cognitive and perceptual processing in human subjects. The introduction of this review considers some of the recent studies of ELF MF exposure upon the EEG, ERPs and cognitive and perceptual tasks. We also consider some of the confounding factors within current human MF studies and suggest some new strategies for further experimentation.

“…Eulitz et al reported a modulation in the high-frequency bands of the EEG after task-relevant but not after standard auditory stimuli [26]. Freude et al found an effect on preparatory slow brain potentials for visual monitoring tasks, but not for less demanding tasks such as finger movements [31,32]. Krause et al reported event-related changes of the desynchonisation/synchonisation responses in the EEG for auditory and visual memory tasks [61,62].…”

“…This influence is practically unknown, although it is generally recognized that such EMFs affect the central nervous system. It has already been demonstrated that EMFs may affect EEG recordings in subjects performing complex mental tasks [8,9], as well as modify human working memory and cognitive functions [10,11]. Thus, it seems reasonable to suppose that an EMF emitted by a mobile phone while driving a motor vehicle may adversely affect a driver's response to road traffic situations.…”

Introduction: The paper reports the results of the determinations of UMTS EMF distributions in the driver's cab of motor vehicle simulators. The results will serve as the basis for future research on the influence of EMF emitted by mobile phones on driver physiology. Materials and Methods: Two motor vehicle driving simulators were monitored, while an EMF source was placed at the driver's head or on the dashboard of the motor vehicle driving simulator. For every applied configuration, the maximal electric field strength was measured, as were the values at 16 points corresponding to chosen locations on a driver's or passenger's body. Results: When the power was set for the maximum (49 mW), a value of 27 V/m was measured in the vicinity of the driver's head when the phone was close to the head. With the same power, when the phone was placed on the dashboard, the measured maximum was 15.2 V/m in the vicinity of the driver's foot. Similar results were obtained for the passenger. Significant perturbations in EMF distribution and an increase in electric field strength values in the motor vehicle driving simulator were also observed in comparison to free space measurements, and the electric field strength was up to 3 times higher inside the simulator. Conclusions: This study can act as the basis of future studies concerning the influence of the EMF emitted by mobile phones on the physiology of the driver. Additionally, the authors postulate that it is advisable to keep mobile phones at a distance from the head, i.e. use, whenever possible, hands-free kits to reduce EMF exposure, both for drivers and passengers.
