Individual FEM model

BESA Research provides head models that are based either on multi-shell spherical head models, standardized realistic

head models using finite elements (FEM), or individual realistic FEM models that were created in BESA MRI. The head model is the

link between the dipole sources and the EEG / MEG signals. It describes the electrical conductivity distribution inside of the head.

By segmenting the different tissues having different conductivities based on the subject's MRI an individual head model can be

constructed which takes into account anatomical differences between subjects. Using the finite element method (FEM) it is then

possible to accurately simulate the EEG / MEG signal generated by a given source distribution.
