The accompanying article by Zentai et al. (1 ) investigates possible effects of radiofrequency (RF) energy from Wi-Fi signals on human brain wave activity. The possible existence of cognitive effects of RF energy has been one of the more contentious discussions in the forever-contentious issue of whether exposure to RF energy at levels that we all commonly encounter in the environment has any health consequences. Are there any physiological effects from such exposures; and if so, do they have any health significance to exposed individuals?
To date, more than 100 studies have been published on effects of RF energy on electroencephalograms (EEGs) recorded in sleeping or awake individuals [for reviews see Regel and Achermann (2 ) and van Rongen et al. (3 )]. In addition, many studies have examined other end points related to cognition and brain function. Not unreasonably, most of these studies were...
