Abstract: The operation of the present device for smoothing of epileptic seizures and epileptic foci in combination with the SQUID which is based on the disorganization of neuronal generators from which the epileptic foci consist of, is done with the use either of one generator of regulating alternated low voltage which produces a given frequency from 2 Hz to 7 Hz (1) and which supplies a certain number of selected coils of one group which consists of similar rows of coils (8, 9, 10, 11, 12) or more groups (21, 22, 23, 24) of similar coils properly arranged in rows as the first group or of generators of alternating, regulating low voltage which produce each one its own frequency from 2 Hz to 7 Hz and which supply simultaneously a definite number of selected coils of one group (31) or more groups (32, 33, 34, 35) of similar coils properly arranged in rows. The coils of the above cases produce magnetic pulses of square or other forms. With the above described device it is possible to smooth the epileptic foci and also other abnormalities.

Description: An electronic ^ device for smoothing of the Central nervous system dysfunctions in conduction with the use of the Biomagneto eter SQUID. The presentation of the invention is referred to an electro¬ nic device for smoothing of dysfunctions of the central ner¬ vous system with the use of the Biomagnetometer SQUID consi¬ sting either of a generator of low alternating voltage and frequency which can produce a given frequency from 2 to 7Hz and which supplies a defined number of chosen coils of one group or more groups of similar coils in order to produce alternating magnetic fields of defi¬ ned magnetic field intensity or of generators of alternating voltage of low frequency which can produce each one its owm frequency from 2 to 7Hz and which can supply simultaneously a defined number of chosen coils in order to produce alternating^magnetic fields. The pulse of the alternating voltage- can be a square or triangu¬ lar or sinusoidal or saw-like form. Analogous form can have the alternating magnetic fields which are produced by the coils the ends of which are connected with the generator ou- put of the alternating voltage. The number and the cross section of the coils turns as well as the shape and the kind of the cores can be varied. The magnetic fields which are produced simultaneously from the coils must be parallel to the alternating magnetic fields which are emitted from the brain epileptic foci.In addition the powers and frequen¬ cies of the emitted magnetic fields from the coils are of ' . ' the same order of magnitude with the ones which are emitted from .the epileptic foci.It is apparent the usefulness of the above device which can smooth the epileptic convulsions in epileptic patients which although are under unticonvulsi- ve medication they continue to havt seizures. The time re¬ quired for smoothing is varied from patient to patient and depends on • the size of the epileptic foci. The smoothing can be repeated by the patient which can have his own device, which can be calibrated with the use of the Biomagnetometer SQUID which gives all the epileptic foci or any other brain dysfun¬ ctions characteristics . Thus in this way could avoid any side effects because the applied magnetic fields are smaller of the earth's magnetic field. Side effects can give the dif- ferent anticonvulsive drugs or the different methods of the diagnostic techniques . It is apparent that the first must localize the epileptic foci with the use of the .SQUID . Prior to the present invention are the research work . and pu¬ blications by the inventors P .A.Anninos and N . F .Tsagas (Brairπ. research Bullet in, Vol.16, 1986, International Journal of -Neuroscience,Vol.37,l In the past have invented methods with the use anticonvulsi¬ ve drags for smoothing of - epileptic seizures for general and focal epilepsy, but witout final canc ellation of epileptic foci . Final cancelletion of epileptic foci can be achieved either with neurosurgery or with the use of leiser , but the disadvantage of these two cores is that they can couse ; .other brain dysfunctions . Most patients.- in order to avoid surgery prefer the drug treatment which is smoothing temporarely the epileptic seizures . Other methods also apply instantly strong magnetic fields of the order of 10 Gauss which also cause other side effects . The present invention which we describe , has the purpose to improve these disadvantages . The device , according to the present-invention has the characteristic to solve the problem of smoothing the epileptic foci or other dysfunctions of central nervous system without the use of .I. . invasive methods It is absolutely safe because the applied alternating magne¬ tic fields are of small frequency (2 to7 Hz) and small inte- nsity 10~ 4 to 10 "8 Gauss which are V/10 4 or 1/10 8 of the earth ' s magnetic field. The duration for smoothing of the epileptic focus is small of the order of several minutes every time is applied the device to the epileptic foci. The smoothing lasts several days or months and the patient can alone repeat the smoothing when he needs because he feels or senses with certain characteristics signs which tell him that is going to have seizures (smell,taste etc) The problem is solved with the us e of either o f one g enerator of alternating voltage of low frequency which can produce a g iven frequency from 2 to 7 Hz and which suppl ies a defi¬ nite number of selected coils in order to produce alterna- ting . ..magnetic fields of definite intensity or from genera¬ tors alternating voltage of low frequency which can produce each one its own frequency from 2Hz to 7 Hz and which sup¬ ply s imultaneously a definite number of selected coils for the production of alternating magnetic fields of definite intensity . The form of the alternating magnetic fields which are produced from the coils the ends of which are connected with the output of the gene rator of the alternating vo ltage is square wave (symmetrical or nonsymmetrical) or triangu¬ lar or sinusoidal or saw- like form . The number of turns and the cross section of the coils as well as the shape and the material of the cores can vary (plastic , ferite and other material of certain magnetic perme ability) . The produced alternating magnetic fields mus t be parallel to the alter¬ nating magnetic fields which are emitted from- the .neuronal generators of the epileptic foci . That is the surface of the coil s must be applied simultaneously and parallel to the proj ected epileptic foci on the skull or in another ubnormal part of the central nervous system . The power and the fre¬ quency of the magnetic fie ld of the coils are of the same order of the magnitude with the magnetic fields which are emitted from the epileptic foci . The precise pos ition of the epileptic foci the intensity and the frequency of the mag¬ netic fields which are emitted from this epileptic foci and which are specific for each patient are defined precisly with the use of the biomagnetometer SQUID . The use of SQUID is described in details in the above mentioned publications .The smoothing effects of the present electronic invention in all patients were encurrengi The advantages of this invention are mainly the fast , pain- les s and noninvasive smoothing of the epileptic foci and the effective reduce of the epileptic seizures . The same patient can perform αt own smoothing .with the use -of the electronic; invention of the present invention . From the above i t is seen that the present electro¬ nic i nvention combines a serious number of advantages . A way of application of the present invention is described below by refering to the figures which accompany it and ex plain with clarity and technical details for understand in order to avoid any misunderstanding . The figure 1 of theφresent ' invention gives the general principale of operation of the device according to the repre¬ sentation of the invention which consists of a generator of al ternating low vol tage and frequency (1 ) which can produce a definite frequency from 2 H z to 7 Hz , of a switch (2) of sele¬ cting the frequencies from 2 Hz to 7 Hz , of switches (3 , 4 , 5 , 6 A ) of selecting the coils for their supply frαn the sele¬ cting frequency and of one or more groups of coils placed in proper order in similar rows. The figure 2 of the present . invention gives the general principal of operation of the device according with the de¬ scription . of the invention which consists of generators of alternating low voltages and frequencies which produce each one its own frequency from 2 Hz to 7 Hz , of a key board - -of selecting generators and coils , of a code maker decode maker of the key board, of a sys tem of memory reading, of a screen display, of a combined circuit and of one group of several groups or several groups of similar coils properly arranged in rows. • The figure 3a of the present invention is the isospectral map which is produced from the measurments by the SQUID of the left temporal region of an epileptic patient before the smoothing . The figure 3b of the present invention is the corresponding map which is produced from measurements os the same region of the brain og the same patient with the use of the SQUID after applying the smoothing which is performed with the use of the present electronic device of the present inven- tion. The figures 1 and 2 give the general principale of operation of the electronic device which can produce alternating magnetic fields for smoothAj dysfaction of the central nervous system, consisting basically o a generator of alternating low voltage which can produce freque cies 2 to 7Hz (l) of a switch of selecting frequencies (2) of switches of selecting coils (3, 4, 5, 6, 7) of one group of similar coils, properly arranged in rows (8, 9, 10, 11, 12) or more similar groups (21, 22, 23, 24), of resistances (13, 14, 15, 16, 17, 18, 19, 20) which connect the coils of the first row (8) with the switch of selecting coils (3) and similar resistances which connect all the other coils of the rows (9, 10, 11, 12) with the switches (4, S, 6, 7) and si¬ milarly for the other groups of coils.

The coils of small diameter about one cm are enclosed between two parallel plan surfaces in such a way so that the axis of the coils to be perpenticular to these surfaces which are located parallel to the projection of the epileptic foci on the skull . The foci (36, 37, 38, 39) with the corresponding power amplitu¬ des above 2200 FT//Hz, below of 2200 FT//Hz, above of 1800 FT/ZHz and below of 1400 FT//Hz resulted from the isospec- tral mapping of the left temporal region of one patient with the use of the SQUID before smoothing. The determination of the coordinates of the epileptic foci (36, 37, 38, 39) ' is done with the use of the SQUID. The powers of the isospec- tral lines resulted also from the mapping with the use of the SQUID. The epileptic foci (36, 37, 38, 39) have been di- sappeared as it is seen in the corresponding region (40) after the application of the present electronic device of the present invention where- the corresponding isospectral amplitudes are belo; 800 FT//Hz.

The .present electronic device for smoothing of the cent¬ ral Nervous System dysfunctions in conjunction with the Bio¬ magnetometer SQUID according with the claims 1 and 2 is cha¬ racterized by the fact ' that it can be consisted of gene- rators of altarnating volatge of low frequency which can' produce each one its own frequency in the range from 2Hz- 7Hz(25), of a keyboard of selecting the generators and coils (26) of a code,maker/decode maker of the keyboard (27), of a system of memory reading (28) of a screen (30) , of a combined circuit (29) and of a group of simi¬ lar coils in proper arrangement in rows (31) or two or three or four or more similar groups of coils (32,33,34,35) where can be included the first group (31) namely a sum of five groups.

The present electronic device for smoothing of the cent¬ ral nervous system dysfunctions in conjuction with the bio¬ magnetometer SQUID according to the claims 1 , 2 and 3 is characterized by the fact that the effectiveness of the function of the invention is based in the proper use of the Biomagnetometer SQUID, at least for the first smoothing of the patient during which the first calibration of the devi¬ ce is performed. With the use of the SQUID the probe of whi¬ ch does not come in contact with skull we are measuring for each patient and for each hemisphere of theebrain 32 poi*- ήbs the distance of which is 1.5 cm which is half of the SQUID sensor diameter in order to avoid between near points magnetic overlαping. These points which form a matrix of rectangular shape are located around the reference points : ofthe 10-20 international point system for electrode place¬ ment. These reference points are T3,T4,P3,P4,F3,F4 for left or right temporal hemisphere, left or right occipital he i- shere and left or right frontal brain region. These 32 point are located with a self-adhesive paper on a plastic hat which is located on the patients head prior t6 the location of the reference points. These 32 points which as we stated above they are 1.5 cm fro one another. , are located in perfectly efined positions in the.-skull with the help of the self-adhesive paper provided thatithe coordinates of the reference points have been defined because by knowing the coordinates of these points we know also the coordinates of all . 32 points and consequently we know the coordinates of the epileptic foci (36,37,38). After is located the probe sensor of the SQUID 3 mm above each measuring point and we are taking 32 consecutive measu¬ rements of one second duration each from each point with sampling frequency of 256 Hz. The measurement of each point is analyzed using Fourier statistical analysis and is exami¬ ned the amplitude distribution of the fourier power spec¬ trum in a given frequency or in a given range of frequencies. With the help of electronic computers we connect all equal power spectra amplitudes for a given frequency or a given frequency range and in this way we obtain maps of iso-spectra amplitudes (figures 3a, 3b). From these maps and from the power spectrum density we can get results if there are epi¬ leptic foci (36,37,38) and also the coordinates and the pow- er of these epileptic foci. Finally from this analysis after the identification of the epileptic foci (36,37,38) with the help of spectra analysis, we can find the frequency of the emitted field from the focus. In this way it is seen that the device is completely connected with the SQUID measure- ments due to the fact that it is necessary for the calibra¬ tion of the device of the present invention. In other words the patient is not able alone to locate the device on his skull without the. above informations because it can disor¬ ganize other regions of his brain which do not need such disorganization if his brain must work properly. The epileptic foci (36,37,38,39) with corresponding magni¬ tudes which varied from 1200fT ϊE and above of 2200 fT Hz with the application of the modified electronic device of the present invention they reduced all to the physiological emitted levels which are below of 800fT ~Hz (Fig.3b) 5.

The present electronic device for smoothing of the cent¬ ral nervous system dysfunctions according to the claims 1,2, 3, 4, 5. is characterized by the fact that the->smoc-thing .and the cancellation of. the -epileptic foci .remains for several. days or months and is due tothe infuence of the external al¬ ternating magnetic field which is inducing inhibitory poten¬ tials in the synapsis of the neurons in the region of the brain in which the electronic device is applied. 7. The present electronic device for the smoothing of centra nervous system dysfunctions according with the claims 1,2,3,4 5, 6,. is characterized by the fact that the time for smoo¬ thing is depending on the depth of the epileptic foci. For deeper epileptic foci is required more time for smoothing. 8.
