“…All these methods have been extensively explored in the contexts of regression-based detection (Baumgartner, Scarth, Teichtmeister, Somorjai, & Moser, 1997;Beckmann & Smith, 2004Fadili, Ruan, Bloyet, & Mazoyer, 2000;Filzmoser, Baumgartner, & Moser, 1999;Friston et al, 1993;Golay et al, 1998;Goutte, Toft, Rostrup, Nielsen, & Hansen, 1999;McKeown et al, 1998;Moser, Diemling, & Baumgartner, 1997;Thirion & Faugeras, 2004;Voultsidou, Dodel, & Herrmann, 2005). The fuzzy variants of clustering Moser et al, 1997), PCA (Friston et al, 1993) and ICA (Beckmann & Smith, 2004McKeown et al, 1998) were successfully used to extract and eliminate components that contain physiological noise unrelated to the activation protocol, substantially improving performance of the standard, regression-based detection.…”
