To study brain cortical and hippocampal activity during exposure to a radiofrequency electromagnetic field, similar to the range used by mobile phones.
It was hypothesized that some brain structures in Lurcher mutant mice should be more sensitive to stimulation with radiofrequency electromagnetic fields as these mice represent a model of neurodegenerative diseases. 20 adult Lurcher mutant mice and 20 healthy wild type mice (control) were exposed. Brain activity was recorded under anesthesia.
ばく露時間: continuous for 40 min
Under exposure, the electrocorticogram evaluation showed a shift towards low frequency components with clear effects in wild type mice and only gentle differences between frequency spectra in Lurcher mutant mice. Measurement of hippocampal rhythmicity showed gentle changes with increase of high frequencies as well as changes of theta wave activity in both groups.
The results support the idea of a different vulnerability of the central nervous system in mice with neurodefective brain to the influence of radiofrequency electromagnetic fields in comparison with controls.
