[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.
