Numerical modelling for EM-Fields and biosystems interactions

2012

In this paper the electromagnetic fields related to the current sources in the human brain are investigated by means of the quasi-stationary approximation. The knowledge of these fields are of great interest to understand the human brain activity regions. By considering the current density produced by neural activity and because no current could ow out of the skull, the numerical model describing the problem can be fully defined. The current sources are simulated as current dipoles into an homogeneous sphere proceeding in the computation by solving the Poissons equation with Neumann boundary conditions. Numerical results relating to a spherical head representation are proposed by considerin…
