“…They found in a longitudinal analysis that higher whole-brain RF-EMF dose was not associated with concentration capacity [25] but was associated with lower figural memory [15], [24]. Although in a previous study we did not find any association between whole-brain RF-EMF doses and volume alterations in the hippocampus or the amygdala, subcortical brain regions involved in memory performance [63], higher RF-EMF exposure induced brain alterations such as denditric remodelling and decreased viable cells in these subcortical structures in rats [64]- [68]. We did not assess figural memory in our study but non-verbal intelligence involves, among other cognitive skills, the ability to recognize visual sequences and remember them to understand and interpret the meaning of visual information.…”

“…Calcium is one of the important signaling substances, and an imbalance of calcium homeostasis can alter many functions of the cell. Previous studies have showed that EMR exposure can alter the calcium channels and receptors on the cell membrane, and influence transport of calcium ions over the cell membrane, which play an important role in cell signaling pathways, and in turn may affect the response of neurotransmitters (90,91). It was reported that the number of opened calcium channel increased with the presence of EMFs, which might resulting in the increased intracellular calcium concentration under EMR exposure (92).…”

With the rapid development of electronic information in the past 30 years, technical achievements based on electromagnetism have been widely used in various fields pertaining to human production and life. Consequently, electromagnetic radiation (EMR) has become a substantial new pollution source in modern civilization. The biological effects of EMR have attracted considerable attention worldwide. The possible interaction of EMR with human organs, especially the brain, is currently where the most attention is focused. Many studies have shown that the nervous system is an important target organ system sensitive to EMR. In recent years, an increasing number of studies have focused on the neurobiological effects of EMR, including the metabolism and transport of neurotransmitters. As messengers of synaptic transmission, neurotransmitters play critical roles in cognitive and emotional behavior. Here, the effects of EMR on the metabolism and receptors of neurotransmitters in the brain are summarized.

In the present study, the effect of 900 MHz radiation exposure on blood biochemical and reproductive parameters was evaluated in adolescent rats. Male albino Wistar rats (8-10 weeks of age) were exposed to 900 MHz radiation (1hr/day, power density - 146.60 µW/cm2) from a mobile phone for 28 days. On 29th day the animals were euthanized and malondialdehyde (MDA), total antioxidants (TA) levels and Glutathione-S transferase (GST) activity were studied in the blood. Reproductive parameters such as total sperm count, percentage of non-motile sperms, and sperm morphology were determined. Testes sections were stained with H(et)E staining and their cellular integrity was evaluated. Caspase-3 activity in the testes was also determined. MDA concentration was increased but TA levels and GST activity were not found to be different in 900 MHz group compared to controls. Sperm motility was found to be slightly reduced in 900 MHz group. Percentage of abnormal sperm was significantly elevated in 900 MHz group. Additionally, loss of germ cells particularly spermatocytes and spermatids was found in the testes of 900 MHz group. Testes caspase-3 activity was slightly elevated in 900 MHz exposed rats. Chronic 900 MHz exposure induced oxidative damage in the blood and lead to alterations in reproductive parameters in rats (Fig. 4, Ref. 33).
