Abstract
V. Rosman (Tver, Russia) proposed a method for three-dimensional mapping of the spatial distribution of alpha-band frequencies over thesurface of the head based on the dispersive analysis. The results of the application of this method in patients with mental illnesses have been carried out on the basis of huge case statistics and are presented in many publications. The electroencephalographic assessment of threedimensional dispersion maps in disorders of mental functions is based on the interpretation of the state of the systemic-functional organization of the bioelectrical activity of the brain as a whole. The most diverse spatial mosaic of alpha distribution is encountered visually. We have identified three main types of spatial distribution of the alpha rhythm according to dispersion maps: scattered, organized, and excessively consolidated. Evaluation of the state of the systemic-functional organization of cortical rhythm using three-dimensional analysis of dispersion maps greatly facilitates the solution of the difficult interpretational problem of decoding the EEG in mental disorders, and finally allows this method to be pulled out of the routine level.
