In this chapter we focus on the use of Independent Component Analysis (ICA) in biomedical systems. Several studies dealing with ICA-based biomedical systems have been reported during the last decade. Nevertheless, most of these studies have only explored a limited number of ICA methods, namely SOBI [7], FastICA [39] and InfoMax [53]. In addition, the performance of ICA algorithms for arbitrary electro-physiological sources is still almost unknown. This prevents us from choosing the best method for a given application, and may limit the role of these methods in biomedical systems.

The purpose of this chapter is first to show the interest ...
