Abstract: An ultra-low frequency magnetic stimulating device comprises a control module for generating a stimulating signal with a frequency lower than 20 Hz, an electric level shifting and converting circuit for shifting the electric level of the stimulating signal to form an AC stimulating signal, and an output module for power amplifying the AC stimulating signal and generating an electric current, an electric field or a magnetic field. The output of the ultra-low frequency magnetic stimulating device is a non-pulsed ultra-low frequency (lower than 20 Hz) current, an electric field or a magnetic field. The output current can be used for electrotherapy when being output to an electrode, or for magnetotherapy when being output to a coil, so as to cure or release diseases related to human brains.

Abstract: The present invention applies computer techniques to the power spectrum analysis of brain wave signals, wherein the power spectrum fluctuations of supra-slow wave is obtained by selecting the maximum value of the power amplitude within 0.5 and 50 Hz and performing multiple analysis of the power spectrum and frequency spectrum, and a series of data and parameters are obtained to provide a basis for cerebral functions testing and disease diagnosis by analyzing the fluctuations. The analysis method comprises the analysis of the conventional power spectrum and may also comprises the analysis of the fluctuation signals of brain wave power, fluctuations of brain wave, S pedigree and further multi-item analyses. And the relevant apparatus implementing such method comprises electrodes, brain wave signal amplifier or a brain wave recording box, a Personal Computer, data processor and terminal processors.
