Effects of radiofrequency electromagnetic field exposure on neurophysiology

The human body is a permissible medium, and radiofrequency electromagnetic field (RF-EMF) waves pass through this medium. The effects exerted by RF-EMF devices such as mobile phones on brain tissues are categorised into thermal and non-thermal effects. The aim of this review was to analyse the interactions and interface between RF-EMF exposure and the nervous system, to ascertain any negative impact on the nervous system at both cellular, molecular and systems level. Original studies that reported on the effects of RF-EMF exposure on the brain function and nervous system from inception to 20 August 2019 were searched online. The PubMed database was utilised. The MeSH system was used to excerpt relevant research studies from PubMed using the following keywords: electromagnetic field, radiofrequency, mobile phone, brain, central nervous system, radiation and neurophysiology. All selected articles were published in the English. Full articles were assessed, and relevant information was extracted. RF-EMF exposure significantly altered several neurophysiological mechanisms based on electroencephalogram studies and molecular and biochemical analysis. However, there was no substantial evidence linking RF-EMF exposure to the pathogenesis of brain tumour.
