Low-level microwave effects on EEG

The results of investigation of low-level modulated microwave effects on human EEG are presented. The theoretical estimation of the sensitivity of cells to microwave fields confirms that very low intensities of radiation would affect living systems. The microwave radiation effects on the vigilance level of the human brain have been studied by comparison with photic stimulation on a homogeneous group of young healthy volunteers. The study of EEG photic stimulation effects at 16 Hz frequency and microwave radiation stimulation effects at 450 MHz frequency modulated with 7 Hz, 16 Hz and 30 Hz frequency shows that the changes caused by these factors in the EEG alpha-wave spectrum have a similar character: depression of alpha-waves and recovering after a 10-20 second period. The microwave effects take place at 7 Hz modulation frequency only and the recovering period for these is longer than for photic stimulation.
