The proposed mechanisms of radio frequency waves (RFWs) on nervous system functions impairment

Abstract
There is a general concern regarding the hazardous health effects of exposure to radiofrequency waves (RFWs) emitted from wireless communication devices. RFWs generated by base transceiver station (BTS) and/or mobile phone have been reported to generate deleterious effects on nervous system, possibly through the non-thermal effects and thermal effects. However, most studies have focused on the non-thermal effects of RFW. In this review, we will consider effects of radiofrequency waves on impairment of nervous system functions. Available data indicate that RFW of relatively low intensity (specific absorption rate (SAR) <2 W/kg) can affect the nervous system. Parameters of RFW exposure, such as frequency, duration, waveform, frequency and amplitude modulation, etc., are important determinants of biological responses. Changes in electrophysiology, blood-brain barrier, morphology, neurotransmitter functions, structural and functional changes in the cell membrane (i.e., NADH oxidase, phosphatidylserine, and voltage-gated calcium channels), genetic effects, and oxidative stress as an important factor have recently been reported in the brain of animals and humans after exposure to RFWs. These changes can lead to functional changes in the nervous system.
