Study of high-frequency electromagnetic field effect on some somatic and neuro-behavioral characteristics in healthy and neurodefective mice

Abstract

The effect of long-term exposure to high frequency electromagnetic field (HF EMF) on some somatic and neural characteristics was studied in neurodefective Lurcher mutant (+/Lc) and normal wild type mice (+/+). Both newborn and young adult (3 months) animals derived from two strains (C3H, B6CBA) were exposed to HF EMF (870 MHz) from 1st to 21st day or from 91st to 120th day respectively. In animals of both groups and controls we observed the development of body weight. Moreover, in the HF EMF exposed adult B6CBA animals we studied spatial learning ability, motor functions and the CNS excitability. To investigate specific energy absorption rate (SAR) in experimental animals we have done the basic 3D calculations of the electromagnetic energy distribution in the simplified model of the mouse. The HF EMF exposed animals exhibited mild differences of body weight between them and unexposed controls. The long-term exposure to HF EMF did not significantly influence the ability to learn in the Morris water maze. However, significant lower swimming speed was found in the irradiated +/Lc as well as lower motor activity of +/+ in the open field when compared to controls. No significant differences were found between HF EMF irradiated animals and controls in examination of the CNS excitability and motor functions.

Age-Dependent Effect of Long-Term Microwave Radiation on Postnatal Neurogenesis in Rats: Morphological and Behavioral Study

“…Hyperactivity in the light-dark test was reported following prenatal exposure of mice to radiofrequency radiation (Aldad et al 2012). Long-term exposure of newborn wild type mice to high frequency EMF (close to mobile phones) mildly influenced motor activity in the open field testing (Vožeh et al 2007). In another experimental paradigm of early life stress, induced by daily parental separation, locomotor hyperactivity was observed (Bock et al 2017).…”
