Abstract: Magnetoencephalograph (MEG) recordings of patients with CNS disorders were obtained using a whole-head 122-channel magnetometer SQUID and analyzed using Fourier statistical analysis. External transcranial magnetic stimulation in the order of pico Tesla (pTMS) was applied on the above patients with proper characteristics (magnetic field amplitude :1-7.5pT, frequency :the α-rhythm of the patient: 8-13 Hz) which were obtained with MEG recordings prior to pTMS. The MEG recordings after the application of pTMS shown a rapid attenuation of the high abnormal activity followed by an increase of the low frequency components toward the patients α-rhythm.
