Research on the Brain. a sampling Megha et al., Microwave Radiation Induced Oxidative Stress, Cognitive Impairment, and Inflammation in Brain of Fischer Rats. Indian J Exp Biol 2012; 50 (12): 889 - 896 “Significant impairment in cognitive function and induction of oxidative stress in brain tissues of microwave exposed rats were observed, in comparison with sham exposed groups… Results of the present study indicated that increased oxidative stress due to microwave exposure may contribute to cognitive impairment and inflammation in brain.” Deshmukh et al., Effect of Low Level Microwave Radiation Exposure on Cognitive Function and Oxidative Stress in Rats.Indian J Biochem Biophys. “Results showed significant impairment in cognitive function and increase in oxidative stress, as evidenced by the increase in levels of MDA (a marker of lipid peroxidation) and protein carbonyl (a marker of protein oxidation) and unaltered GSH content in blood. Thus, the study demonstrated that low level MW radiation had significant effect on cognitive function and was also capable of leading to oxidative stress.” Kesari et al., Effect of 3G cell phone exposure with computer controlled 2-D stepper motor on non-thermal activation of the hsp27/p38MAPK stress pathway in rat brain. Cell Biochem Biophys. 2014 Mar;68(2):347-58. Result shows that microwave radiation emitted from 3G mobile phone significantly induced DNA strand breaks in brain. Meanwhile a significant increase in micronuclei, caspase 3 and apoptosis were also observed in exposed group. Study shows that the oxidative stress is the main factor which activates a variety of cellular signal transduction pathways, among them the hsp27/p38MAPK is the pathway of principle stress response. Results conclude that 3G mobile phone radiations affect the brain function and cause several neurological disorders. Naziro?lu M. and Gumral 2009. Modulator effects of L-carnitine and selenium on wireless devices (2.45 GHz)-induced oxidative stress and electroencephalography records in brain of rat. Int J Radiat Biol. 85(8): 680-689. Rats exposed to 2.45 GHz 60 min/day for 28 days had lower cortex brain vitamin A (p < 0.05), vitamin C (p < 0.01) and vitamin E (p < 0.05) concentrations. Júnior LC, Guimarães ED, Musso CM, Stabler CT, Garcia RM, Mourão-Júnior CA, Andreazzi AE. Behavior and memory evaluation of Wistar rats exposed to 1·8 GHz radiofrequency electromagnetic radiation. Neurol Res. 2014 Jan 27:1743132813Y0000000276. Frequency of rearing was increased by 193.3%, revealing an increase in exploratory activity of the animals, which is also related to anxiety, depression, and stressful behavior.

Brain Res. 1238, 224–229. Prenatal exposure caused a progressive postnatal decline in the number of granule cells of dentate gyrus of the hippocampus of offspring. Qiao S, Peng R, Yan H, Gao Y, Wang C, Wang S, Zou Y, Xu X, Zhao L, Dong J, Su Z, Feng X, Wang L, Hu X. Reduction of Phosphorylated Synapsin I (Ser-553) Leads to Spatial Memory Impairment by Attenuating GABA Release after Microwave Exposure in Wistar Rats. PLoS One. 2014 Apr 17;9(4):e95503. doi: 10.1371/journal.pone.0095503. eCollection 2014. A decrease in spatial memory performance after non-thermal microwave exposure. "Our experiments on Wistar rats and PC12 cell line suggest that microwave exposure (30 mW/cm2) can induce behavioral and cognitive dysfunction via altered GABAergic transmission. We have shown for the first time that reduced p-Syn I (ser-553) expression plays a critical role in this effect." Bas, O., Odaci, E., Mollaoglu, H., Ucok, K., Kaplan, S., 2009a. Chronic prenatal exposure to the 900 megahertz electromagnetic field induces pyramidal cell loss in the hippocampus of newborn rats. Toxicol. Ind. Health 25, 377–384. A significant reduction in the total number of pyramidal cells in the cornu ammonis of the hippocampus, which involves short-term memory and learning. Sixteen-week old rats are comparable to the age of human teenagers. Bas, O., Odaci, E., Kaplan, S., Acer, N., 2009b. 900 MHz electromagnetic field exposure affects qualitative and quantitative features of hippocampal pyramidal cells in adult rat. Brain Research. 1265, 178–185. A statistically significant decrease in the pyramidal cells of the hippocampus and an increase in dark cells. Bin Lv, Zhiye Chen, Tongning Wu, Qing Shao, Duo Yan, Lin Ma, Ke Lu, Yi Xie. The alteration of spontaneous low frequency oscillations caused by acute electromagnetic fields exposure. Clinical Neurophysiology. Published online 4 September 2013. 30 min LTE 4G exposure modulated the spontaneous low frequency fluctuations in brain regions. Jing J et al, (March 2012) The influence of microwave radiation from cellular phone on fetal rat brain, Electromagn Biol Med. 2012 Mar;31(1):57-66. Epub 2012 Jan 23 Pregnant rats were exposed to different intensities of microwave radiation from cellular phones. Significant content differences were found in superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), malondialdehyde (MDA), noradrenaline (NE), dopamine (DA) after fetal brains were assayed. “Through this study, we concluded that receiving a certain period of microwave radiation from cellular phones during pregnancy has certain harm on fetal rat brains.” Razavinasab M1, Moazzami K, Shabani M. Maternal mobile phone exposure alters intrinsic electrophysiological properties of CA1 pyramidal neurons in rat offspring.Toxicol Ind Health. 2014 Mar 6. "The results of the passive avoidance and Morris water maze assessment of learning and memory performance showed that phone exposure significantly altered learning acquisition and memory retention in male and female rats compared with the control rats. Our results suggest that exposure to mobile phones adversely affects the cognitive performance of both female and male offspring rats using behavioral and electrophysiological techniques."
