Query: On the modeling of brain fibers in the EEG forward problem via a new
  family of wire integral equations   Source localization based on electroencephalography (EEG) has become a widely
used neuroimagining technique. However its precision has been shown to be very
dependent on how accurately the brain, head and scalp can be electrically
modeled within the so-called forward problem. The construction of this model is
traditionally performed by leveraging Finite Element or Boundary Element
Methods (FEM or BEM). Even though the latter is more computationally efficient
thanks to the smaller interaction matrices it yields and near-linear solvers,
it has traditionally been used on simpler models than the former. Indeed, while
FEM models taking into account the different media anisotropies are widely
available, BEM models have been limited to isotropic, piecewise homogeneous
models. In this work we introduce a new BEM scheme taking into account the
anisotropies of the white matter. The boundary nature of the formulation allows
for an efficient discretization and modelling of the fibrous nature of the
white matter as one-dimensional basis functions, limiting the computational
impact of their modelling. We compare our scheme against widely used
formulations and establish its correctness in both canonical and realistic
cases.
