On Forward Model Uncertainty in EEG Source Localization
Carsten Stahlhut, Morten Mørup, Ole Winther, Lars Kai Hansen · 2011
We give two quantitative contributions to electro-encephalography (EEG) source localization. First, we investigate how erroneous forward models influence current density source reconstruction. Second, we present the first unified hierarchical Bayesian framework that simultaneously reconstructs the sources and the forward model. Modeling the uncertainties involved in the forward model, i.e. the representation of the conductivity distribution, the cortical surface, and the electrode locations, has the potential of giving better source location.
