Numerical modelling for EM-Fields and biosystems interactions

Risultato della ricerca: Other


In this paper the electromagnetic fields related to the current sources in thehuman brain are investigated by means of the quasi-stationary approximation.The knowledge of these fields are of great interest to understand the humanbrain activity regions. By considering the current density produced by neuralactivity and because no current could ow out of the skull, the numerical modeldescribing the problem can be fully defined. The current sources are simulatedas current dipoles into an homogeneous sphere proceeding in the computation bysolving the Poissons equation with Neumann boundary conditions. Numericalresults relating to a spherical head representation are proposed by consideringalso multilayered model with di erent conductivities and compared with theanalytical solutions.
