[The spatial organization of the electrical processes in the brain: the problems and the solutions].

In the paper the theoretical problems are discussed of the spatial organization of brain electrical activity. It is considered as a multilevel realization of synergetic principle in formation of functional systems, which underlie behavior and mental activity. The role is discussed of the spatial-temporal superposition of coherent structures of potentials in generation of the cortical fields of increased activity, which realize the integrative and associative functions. A hypothesis is proposed about the alignment of "energy" and "information" factors of coherent structures as one of the important characteristics of efficiency of biological energy-information processes. The necessity is emphasized of taking into account both linear and nonlinear correlations of biopotentials to gain an insight into the forms and functional significance of their spatial organization.
