SPATIAL-ORGANIZATION OF BRAIN ELECTRICAL PROCESSES, PROBLEMS AND SOLUTIONS

In the paper the theoretical problems are discussed of the spatial org anization of brain electrical activity. It is considered as a multilev el realization of synergetic principle in formation of functional syst ems, which underlie behavior and mental activity. The role is discusse d of the spatial-temporal superposition of coherent structures of pote ntials in generation of the cortical fields of increased activity, whi ch realize the integrative and associative functions. A hypothesis is proposed about the aligment of ''energy'' and ''information'' factors of coherent structures as one of the important characteristics of effi ciency of biological energy-information processes. The necessity is em phasized of taking into account both linear and nonlinear correlations of biopotentials to gain an insight into the forms and functional sig nificance of their spatial organization.
