| Abstract: | Background The electroencephalogram (EEG) reflects the electrical activity in the brain on the surface of scalp. A major challenge in
this field is the localization of sources in the brain responsible for eliciting the EEG signal measured at the scalp. In
order to estimate the location of these sources, one must correctly model the sources, i.e., dipoles, as well as the volume
conductor in which the resulting currents flow. In this study, we investigate the effects of dipole depth and orientation
on source localization with varying sets of simulated random noise in 4 realistic head models. |
