Pulsed radio frequency radiation affects cognitive performance and the waking electroencephalogram


Regel, S J; Gottselig, J M; Schuderer, J; Tinguely, G; Rétey, J V; Kuster, N; Landolt, H P; Achermann, P (2007). Pulsed radio frequency radiation affects cognitive performance and the waking electroencephalogram. NeuroReport, 18(8):803-807.

Abstract

We investigated the effects of radio frequency electromagnetic fields on brain physiology. Twenty-four healthy young men were exposed for 30 min to pulse-modulated or continuous-wave radio frequency electromagnetic fields (900 MHz; peak specific absorption rate 1 W/kg), or sham exposed. During exposure, participants performed cognitive tasks. Waking electroencephalogram was recorded during baseline, immediately after, and 30 and 60 min after exposure. Pulse-modulated radio frequency electromagnetic field exposure reduced reaction speed and increased accuracy in a working-memory task. It also increased spectral power in the waking electroencephalogram in the 10.5-11 Hz range 30 min after exposure. No effects were observed for continuous-wave radio frequency electromagnetic fields. These findings provide further evidence for a nonthermal biological effect of pulsed radio frequency electromagnetic fields.
