In the probe test, the exposed group could not locate the platform and exhibited a significantly higher mean latency (i.e., 3-fold higher) to reach the target quadrant, and they spent only half the time that the controls spent in the target quadrant. 2013;23:306. Wang et al. The levels of NMDA receptor subunits were increased 1 month after irradiation. Interphone study group. CAS PubMed Nuclear pyknosis and capillary congestion are also observed. The results showed that at 6h, 1 d and 3 d after exposure, the groups in which the average power density was 10mW/cm2 or 50mW/cm2 displayed significant deficits in spatial learning and memory. They summarized the characteristics and functions of hippocampus-related miRNAs following irradiation with microwaves, and these data laid a foundation that clarified the molecular mechanisms underlying microwave-induced injury to hippocampal learning and memory and suggested potential therapeutic targets. [61] found that after pregnant rats were irradiated with 9.417GHz microwaves, the behavior of their offspring differed, and the outcome was sex-dependent. 2005;161:3314. 2009;64:2314. Most studies have suggested that microwave radiation can cause EEG abnormalities in experimental animals and participants, but some negative results have also been reported in studies using low-power microwaves. For example, it can shorten reaction times so that people can better cope with danger. In the group treated with 0.8W/kg, there was no significant change. Since mobile phones are used in positions very close to the human body and require a large The progeny brain oxidative balance and serum biochemistry, such as phosphorus, magnesium, glucose, triglycerides and calcium levels, were disrupted [60].

Chin J Radiol Med Prot. Arch Environ Health. Microwave frequencies for which the wavelengths are the same order of magnitude as the dimensions of human body produce close coupling between the body and the microwave field. However, there is little scientific evidence to demonstrate that children are more sensitive to electromagnetic radiation than adults [24, 25]. radiation with wavelengths. [38] exposed Wistar rats to a 2.856GHz pulsed microwave field for 6min. For example, people who have used mobile phones for more than 10years have a clearly higher risk of brain tumors. 2 Researchers have been working. Brain electrical activity originates from the membrane potential of the neuron itself and the fluctuation in membrane potential. [104] found that exposure to a 1.9GHz pulse-modulated RF field for 4h at 0.1, 1.0, and 10W/kg did not affect gene expression in U87MG glioblastoma cells. In industrial fields, exposure is usually occupational, and its sources include the surgical and physiotherapeutic use of diathermy, dielectric heating (i.e., heating and vulcanization applications), microwave ovens, magnetic resonance imaging (MRI) medical diagnostic equipment, radar, military and research microwave systems, electricity-supplying networks, and electricity-distributing and transmitting equipment [3].

The results showed that gestational Wi-Fi exposure and restraint adversely affected offspring neurodevelopment and behavior in adulthood. Whole-body exposure to 2.45 GHz electromagnetic fields does not alter 12-arm radial-maze with reduced access to spatial cues in rats. The largest problem in these studies is that they used different parameters, such as the frequency, modulation, power density and irradiation time, to apply microwave radiation, in addition to using a variety of research methods. Morris R. Developments of a water-maze procedure for studying spatial learning in the rat. 2010;473:525. 2011;31:2293301. 2002;5:18995.

Merola P, Marino C, Lovisolo G, Pinto R, Laconi C, Negroni A. Additionally, in the 2.4W/kg group, neuronal filopodial density and activity were lower on day 8, and there was a reduction of the dendritic spine maturity on day 14. Role of distinct NMDA receptor subtypes at central synapses. Radial arm maze performance of rats following repeated low level microwave radiation exposure. In 35% of cases, soldiers work in intermediate and hazardous zones and in 22%only in the intermediate zone. After studying these effects, Hertel concluded that microwaving food leads to food degeneration. Neurosci Lett. 1994;8:714. 2010;2010. 2015;91:55561. One reason for this difference may be that the water maze experiment is driven by aversion, whereas the arm maze experiment is driven by appetite. SAR Value There are guidelines internationally for short term exposure to cell phone frequency microwaves, defined in terms of the Specific Absorption Rate (SAR), the rate at which energy is absorbed by the human body when exposed to radio frequency radiation. The effects of microwaving a human body Lia Koltyrina/Shutterstock But there are parts of the human body that are more prone to "cooking" fast, such as the eyeballs and testes. Cordless phone radiation effect flows in a human body same way in the mobile phone [13]. 2007;210:63544. Environ Toxicol Pharmacol. Electromagn Biol Med. However, impaired learning and memory were only observed in males. found that long-term treatment with a low dose of microwave radiation reduced the activity and the number of excitatory synapses.

In 43% of devices, military personnel are not exposed to an electromagnetic field. Oxidative stress refers to an imbalance between oxidants and antioxidants in vivo and is characterized by a biochemical state that tends toward oxidization, including the formation of oxygen free radicals (i.e., ROS) and nitrogen radicals reactive nitrogen species (RNS), which play major roles in oxidation. The normal function of synaptic vesicles depends on the normal expression of related proteins. The microwave will do its intended job of heating and will start to burn (or cook) the skin tissue.

Based on this background, in this review, we first summarized the effects of microwave radiation on the central nervous system, including the epidemiology, morphology, electroencephalograms, learning and memory abilities and mechanisms of underlying brain dysfunction from the perspective of synaptic structures and functions, oxidative stress and apoptosis, protein synthesis, genes and individual susceptibility and energy metabolism. 2016;25:31827. 2007;28:187380. statement and Biomed Environ Sci. The authors detected the EEG within the frequency bands of 0.530.0Hz for 5 consecutive days. pability of the body (thus, a thermal effect), whereas the standard of the U.S.S.R. and Poland are based upon the interaction of the microwave fields with the brain and central nervous system as measured by neurological or behavior effects. However, there was no change in the frequency of AMPA mEPSCs or the amplitudes of N-methyl-d-aspartate (NMDA) mEPSCs. Functional plasticity is affected in other ways, including the abnormal release and uptake of brain amino acids such as choline and monoamine neurotransmitters, a decrease in excitatory postsynaptic potential amplitudes and spikes in long-term potentiating (LTP) in the medial perforated pathway (MPP) in the dentate gyrus (DG) [27]. Synaptic plasticity is a special function of synapses, which play an important role in learning and memory processes [46], including structural and functional plasticity.

The authors therefore proposed that synaptic conduction disorders are associated with damage to cognitive functions. 2016;74:99107. 2004;155:3743. [14] found that gliomas are not preferentially located in the parts of the brain with the highest exposure. miRNAs are non-coding sequences with a length of approximately 22 nucleotides that have roles in cell development and differentiation and are also linked to signal transduction and tumorigenesis. RF energy has the ability to heat human tissue, much like the way that microwave ovens heat food, and can be hazardous if the exposure is sufficiently intense or prolonged. 2014;53:22230.

Thus, the committee suggested that in the future, studies should explore the border between thermal and non-thermal effects and that specific effects, such as triggering the onset of thermoregulatory reactions, should be defined. Moreover, the popularization of mobile phones has made them the main source of brain exposure to radiation. Above all, because of biases and variations in investigation methods, no conclusive evidence has been presented that microwaves cause cancer. Dendritic spines, which are small protrusions that extend from dendritic shafts, are also cellular compartments containing signaling molecules that are important for synaptic transmission and plasticity [88,89,90,91].
