Calculation of EEG Forward Problem with Anisotropy by the Finite Element Method

摘要

The electric current distribution produced by dipoles in human brain is simulated by the finite element method. The current dipoles are adopted to simulate the nerve sources in the brain. The finite element formula related to dipole sources and anisotropic media is derived. An approach for creating a symmetrical stiffness matrix of the finite element equation system in the computation of potential problems with anisotropic media is presented. In the simulation the realistic shape of the head with anisotropic conducting media is considered.
