Effect of mobile phone emitted radiation on the power frequency and amplitude of electroencephalographic (EEG) activity in rats

摘要

The aim of the present study was to investigate the effect of mobile phone (MP) (935.2 – 960 MHz, 0.35 mW/cm2) on the power frequency and amplitude of electrocorticographic ECoG recording. The brain cortex of anaesthetized rats were exposed to electromagnetic fields (EMFs) emitted from a mobile phone 2 h daily for one week and ECoG recording were carried out through trephine openings in the skull. The effect of EMFs on the brain activity was analyzed from activity patterns recorded from both brain cortex and skull: before exposure, immediately after exposure and after 7, 9, 11, 13 days from stopping exposure. The obtained results showed significant changes in the power frequency and amplitude of brain activity of rat exposed to the radiation emitted from MP and these changes attained their control values after approximately 11 days from stopping radiation exposure.
