Abstract

In the article, based on clinical material obtained in the course of a study of patients with depression, an approach was applied to the analysis of the dependences of electroencephalogram channels using correlation ratios. It can objectively evaluate the properties of connections in any of their models (linear and non-linear). On the basis of the constructed matrices of correlation ratios, the possibility of analyzing paired dependences is shown in order to determination of parameters that differ for the norm and pathology. The direction of the connections between the leads was also established. In our opinion, differences in interhemispheric occipital connections are the most significant. This approach could become the basis for determining unique quantitative markers of depressive states and other neuropsychiatric disorders.
