Your mobile phone is not only a carcinogenic, radiation emitting device, but may alter the structure and function of the brain, including brain wave activity that is intimately connected to cognition, mood and behavior.
A concerning new clinical study published in PLoS One titled, "EEG Changes Due to Experimentally Induced 3G Mobile Phone Radiation," has revealed that so-called 3rd generation (3G) cell phone technology has widespread brain wave disrupting activity in subjects exposed to real-world like conditions, i.e. 15-minute "talk time" exposure to the ear area.
The study abstract describes the experimental design and results:
The aim of this study was to investigate whether a 15-minute placement of a 3G dialing mobile phone causes direct changes in EEG activity compared to the placement of a sham phone. Furthermore, it was investigated whether placement of the mobile phone on the ear or the heart would result in different outcomes. Thirty-one healthy females participated. All subjects were measured twice: on one of the two days the mobile phone was attached to the ear, the other day to the chest. In this single-blind, cross-over design, assessments in the sham phone condition were conducted directly preceding and following the mobile phone exposure. During each assessment, EEG activity and radiofrequency radiation were recorded jointly. Delta, theta, alpha, slow beta, fast beta, and gamma activity was computed. The association between radiation exposure and the EEG was tested using multilevel random regression analyses with radiation as predictor of main interest. Significant radiation effects were found for the alpha, slow beta, fast beta, and gamma bands. When analyzed separately, ear location of the phone was associated with significant results, while chest placement was not. The results support the notion that EEG alterations are associated with mobile phone usage and that the effect is dependent on site of placement. Further studies are required to demonstrate the physiological relevance of these findings."
While previous research has found that mobile phone exposure affects alpha brain wave activity, and subsequent behavior (insomnia), this is the first placebo-controlled, single-blinded study of its kind to show that as little as 15 minutes of 3G cell phone technology exposure directly to the ear, "is associated with increased activity of the alpha, beta, and gamma frequency bands in nearly every brain region." In other words, typical mobile phone exposure resulted in electrophysiological changes that resulted in measurable alterations in nearly the entire brain's structure/function. Even though it is now common knowledge that cell phone radiation is powerful enough to disrupt sensitive equipment within an airplane (think: airplane mode) or hospital, there is still resistance to acknowledging it may adversely affect the human brain, an electrical impulse sensitive organ.
Moreover, since brain waves are believed to encode rules for behavior, altering brain wave activity could have considerable downstream affects on behavior and consciousness. To learn more about the potential of mobile phone and related electromagnetic radiation to affect cognition and behavior, read the Scientific American article, "Could certain frequencies of electromagnetic waves or radiation interfere with brain function?", which explains why these concerns are valid.
