Sofomore: Combined EEG Source and Forward Model Reconstruction

Carsten Stahlhut, Morten Mørup, Ole Winther, Lars Kai Hansen

Abstract: We propose a new EEG source localization method that simultaneously performs source and forward model reconstruction (SOFOMORE) in a hierarchical Bayesian framework. Reconstruction of the forward model is motivated by the many uncertainties involved in the forward model, including the representation of the cortical surface, conductivity distribution, and electrode positions. We demonstrate in both simulated and real EEG data that reconstruction of the forward model improves localization of the underlying sources.
