Abstract
The impact of low intensity alternating magnetic field (LIAMF) and low-frequency pulsed vortex magnetic field (LFPVMF) of low nonthermal intensity on the magnetoencephalogram (MEG) characteristics of white outbred rats and humans has been analyzed and the results are presented. A number of different trends in rat MEG changes after the LIAMF action has been discovered: an increase of delta/theta rhythms, equalizing of all MEG component levels and alpha rhythm degradation, an increase of beta/gamma rhythms. The analysis of volunteer magnetoencephalogram changes has demonstrated the alpha rhythm stimulation and the decrease of its frequency deviation after the LFPVMF action in the definite sequence order of oscillating modes.
