This pilot study was conducted to investigate whether multiple electrophysiological activities could be altered when exposed to extremely low frequency pulsed electromagnetic field (PEMF) over a consecutive 5 day period. Our results revealed substantial changes in electro­encephalo­graphic hemispheric asymmetry, observed at the theta band posterior predominance, an increase in the low frequency heart rate variability, changes in the surface skin temperature and skin bioelectric impedance fluctuations in its frequency spectrum. Due to the small sample size these results reveal no solid and conclusive evidence in the possible alterations in electro­physiological responses due to PEMF.
