To investigate whether exposure of rat brains to GMS microwaves induced DNA breaks and changes in gene expression, Belyaev et al. 2015;148:150. Studies have also suggested that long-term exposure to 2.4GHz microwave radiation may lead to adverse effects, as observed in neurodegenerative diseases that originate from the altered expression of some miRNAs. They found that escape times were substantially decreased when the animals were trained while exposed to the phone.

CAS Microwave radiation can induce oxidative and nitrosative stress, which lead to hippocampal neuronal and non-neuronal apoptosis via the oxidative damage of cellular constituents (i.e., nucleic acids, proteins and lipids) and subsequent over expression of p53, which up-regulates Bax and down-regulates pro-caspase-3 and full-length/uncleaved poly-ADP-ribose polymerase (PARP) 1, eventually inducing neuronal degeneration via apoptosis [76].

When nerve endings are excited, the vesicles release their contents into the synaptic cleft, resulting in synaptic transmission.

However, to date, with the exception of high-power microwave radiation, which has widely established hazardous effects, the biological effects of microwaves remain controversial.

The microwave energy can be changed to warm up the food because this energy is absorbed by food & it does not prepare food contaminated or radioactive. Among radar workers exposed to 1418GHz microwaves, the somatic symposium anxiety and insomnia, social dysfunction and severe depression were caused [19]. These spines have been reported to share a close relationship with learning and memory abilities, and when protein synthesis in dendritic spines is blocked, new spine growth and the development of long spines are both decreased [91].
