Oostendorp et al. [ 10] conducted in vivo experiments by using a boundary element head model and in vitro experiments to estimate the conductivity ratio, and both methods suggested a different BSCR value of 15.
First, for determining the optimal forward model for magnetoencephalography (not electroencephalography) required for source reconstruction, an individualized cortical mesh is not superior to a canonical model provided that a realistic boundary element head model is used (Henson et al., 2009).

The element (regionBase) is child of the element (head), and a document may contain either several or no element (regionBase).
In our source localization methods, we used a three-shell realistically shaped boundary element head model (BEM) constructed from tessellated surfaces of inner-skull, outer-skull and outer-skin (scalp) [33].
Next we extended our analysis to a more realistic, three-dimensional finite element head model (FEM) created using the Mimics software package [ 37].
In order to understand further the mechanisms of CES, we aimed to model CES using a magnetic resonance imaging (MRI -derived finite eleMRI -deriveddel including cortical and also subcortical structures.
All MR imaging was performed using a 3.0 T MR system (Magnetom Verio, Siemens Medical Solutions, Erlangen, Germany) with an 8-element head matrix coil.

All MRI data were collected on a 3T Siemens Trio system with a 12-element head coil.
The MRI was performed with a 12-element head-neck coil.
