Aim of study (acc. to author)

This study was designed to examine the effects of 450 MHz electromagnetic fields on human central nervous system function concerning conscious visual perception in vivo.

Background/further details

Twenty healthy volunteers (9 male, 11 female), aged between 22-34 years participated in this study. Each subject performed two tests (electromagnetic field exposure and sham exposure) consisting of 100 trials each.
