[A direct problem of electroencephalography using the spherical approach].

A solution of the direct problem of electroencephalography was carried out within the framework of multilayer sphere model consisting of homogenous omic spherical kernel covered with five omic layers modelling epicortical liquor, three-layer bone of the skull, scalp. Solutions of more simple models cited in literature are particular variants of this general one. By means of numerical simulation solutions of multilayer spheres of different complexity are compared and a notion of the simplest adequate model is worked out.

[Calculation of the EEG amplitude during differential recording of a potential in a homogeneous unlimited medium].

It is proved by means of numerical simulation, that the potential derived by differential derivation of EEG is well approximated by the potential on spherical surface in unbounded unlimited medium. The supposed imitating formula in comparison with traditional solution within the model of multilayer sphere, much reduces the volume of calculations, being an important pre-condition of on-line analysis of experimental EEG by means of computer.
