DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention is an electronic device for smoothing dysfunctions of the central nervous system in combination with the use of a Biomagnetometer SQUID. The electronic device comprises a generator of alternating voltage and low frequency which can produce a given frequency from 2 to 7 Hz and which supplies a given number of selected coils from one or more groups of similar coils for the production of alternating magnetic fields. The intensity of the magnetic fields is regulated by microprocessors. A plurality of generators of alternating voltage and low frequency may be provided. Each of the generators can produce a frequency from 2 to 7 Hz and can supply simultaneously a definite number of selected coils for the production of alternating magnetic fields, having a regulated intensity and frequency by microprocessors. The magnetic fields which are simultaneously produced from the coils must be parallel to the alternating magnetic fields which are emitted from the epileptic foci of the brain. The power spectra and frequencies of the emitted magnetic fields of the coils are of the order of the magnetic fields which are emitted from the epileptic foci, that is from 0.5 pT to 7.5 pT. The limit of the intensities can be extended. Satisfactory results can be obtained using 64 similar coils, which is the number of the measuring points of the left and right brain hemispheres. The epileptic foci are first localized with the use of the SQUID. The present electronic device is adjusted with the use of the SQUID, which gives all of the characteristics of the epileptic foci or any other brain malfunction. Thus, the first step is to localize the epileptic foci with the use of the SQUID, and then to adjust properly the electronic device of the present invention according to the characteristic properties of the localized epileptic foci.
SUMMARY OF THE INVENTION
Prior to the present invention were the following publications by the present inventors P. A. Anninos and N. F. Tsagas: Brain Research Bulletin, Vol. 16, 1986, and International Journal of Neuroscience, Vol. 37, 1987. The device according to the present invention solves the problem of smoothing the epileptic foci or any other dysfunctions of the central nervous system without the use of the known invasive methods. It is perfectly safe because the applied alternating magnetic fields are of low frequency (from 2-7 Hz) and low intensity (from 0.5 pT to 7.5 pT). This problem is solved with the use of either of one generator of low alternating voltage and frequency which can produce a given frequency from 2-7 Hz, and which supplies a given number of selected coils, to produce alternating magnetic fields of which the intensity and frequency are regulated by microprocessors, or with the use of multiple generators of low alternating voltage and frequency which can each produce a frequency from 2-7 Hz and can supply simultaneously a given number of selected coils for the production of alternating magnetic fields of which the intensity and frequency are adjusted using microprocessors.
The device is activated with the necessary characteristic elements of the epileptic foci, which are obtained with the use of the biomagnetometer SQUID, and which are properly stored in an integrated circuit of a microprocessor. The proper storage of the data is done using proper software which is written in basic computer language by the present inventors. The computer program reads the data which are stored on the computer disk or diskette during the analysis of the data recorded from the epileptic foci of a patient with the use of the SQUID for all of the 64 or 128 points of skull. These data are stored with the software program in one matrix with three columns, where in the first column are stored the left temporal or occipital or frontal points, and in the other two columns are stored the frequencies and intensities of the magnetic fields which are emitted from each point. The same is done for the right temporal, occipital and frontal regions of the skull
