We have carried out a controlled experiment in pursuit of the objective of studying the dynamics of EEG alpha-rhythm characteristics in transcranial magnetic stimulation of 32 patients with treatment-resistant depression. TMS was carried out when thymoanaleptic therapy was found to be ineffective. Spectral analysis of EEG parameters was carried using the Fast Fourier transform method averaging no less than 30 epochs at 2 sec. each. Following the transcranial magnetic stimulation, greatest alterations have been observed in the alpha-rhythm range – its index increased in all cortical areas, but the greatest increase in alpha-rhythm activity was seen in the occipital cortical areas, thus forming the normal zonal distribution of the main EEG rhythm.
