title: Influence of source separation and montage on ictal source localization.
abstract: The aim of this paper is to evaluate the influence of the reference electrode (introduced to form an augmented average montage) and of the artifact elimination by blind source separation on the ictal electrical source imaging. We present here a preliminary study on one patient only. The results seem to indicate that the montage (and thus the reference handling method) has a limited but existent influence on the quality of the source localization. Artifact elimination highly improves this quality as well.
