CSD methodology has been successfully applied in other sensory modalities and for other components as well. For example, the advantage of reference-independence of CSD topographies (Nagamine et al., 1992) and their superiority over field potentials in localizing electrical activity (Tomberg, 1991) have been noted for the somatosensory evoked response. Likewise, striate and extrastriate activity has been separated by the surface Laplacian for the pattern onset VEP (Manahilov et al., 1992). As an incomplete list of other examples, CSD methods have been applied with equal success to study event preparation (Tandonnet et al., 2003), event-related desynchronization (Pfurtscheller, 1988; Babiloni et al., 2004), novelty detection (Friedman and Simpson, 1994; Yago et al., 2003; Tenke et al., 2010), episodic and working memory (Kayser et al., 2006, 2007, 2009, 2010a), error processing (Allain et al., 2004; Cavanagh et al., 2009), resting EEG (Tenke and Kayser, 2005; Tenke et al., 2011), early visual processing (Kayser et al., in press), and even olfactory function (Kayser et al., 2010b).
