Query: Realistic head modeling of electromagnetic brain activity: An integrated
  Brainstorm pipeline from MRI data to the FEM solution   Human brain activity generates scalp potentials (electroencephalography EEG),
intracranial potentials (iEEG), and external magnetic fields
(magnetoencephalography MEG), all capable of being recorded, often
simultaneously, for use in research and clinical applications. The so-called
forward problem is the modeling of these fields at their sensors for a given
putative neural source configuration. While early generations modeled the head
as a simple set of isotropic spheres, today s ubiquitous magnetic resonance
imaging (MRI) data allows detailed descriptions of head compartments with
assigned isotropic and anisotropic conductivities. In this paper, we present a
complete pipeline, integrated into the Brainstorm software, that allows users
to generate an individual and accurate head model from the MRI and then
calculate the electromagnetic forward solution using the finite element method
(FEM). The head model generation is performed by the integration of the latest
tools for MRI segmentation and FEM mesh generation. The final head model is
divided into five main compartments: white matter, grey matter, CSF, skull, and
scalp. For the isotropic compartments, widely-used default conductivity values
are assigned. For the brain tissues, we use the process of the effective medium
approach (EMA) to estimate anisotropic conductivity tensors from
diffusion-weighted imaging (DWI) data. The FEM electromagnetic calculations are
performed by the DUNEuro library, integrated into Brainstorm and accessible
with a user-friendly graphical interface. This integrated pipeline, with full
tutorials and example data sets freely available on the Brainstorm website,
gives the neuroscience community easy access to advanced tools for
electromagnetic modeling using FEM.
