Diffusion-weighted imaging (DWI)-defined clusters are from the current study, and the colors listed refer to those shown in Figures 2 and 7. Cytoarchitectonic regions are based on the descriptions of Choi, Caspars, and Scheperjans and colleagues (Caspers et al., 2006, 2008; Choi et al., 2006; Scheperjans et al., 2008a,b). Retinotopic map designations are based on several studies (Schluppeck et al., 2005; Silver et al., 2005; Levy et al., 2007; Swisher et al., 2007; Konen and Kastner, 2008). The designations used by a group of researchers based in the Massachusetts General Hospital (MGH) and Katholieke Universiteit Leuven (Leuven) are listed in the fourth column (Vanduffel et al., 2002a; Denys et al., 2004b; Orban et al., 2006; Durand et al., 2007, 2009; Georgieva et al., 2009). Other designations based on the behavioral condition in which activations have been found are listed in the final column: a region referred to as AIP or hAIP region reported at the medial boundary of the second most anterior IPL cluster (Fig. 7, blue) (Binkofski et al., 1999; Grefkes et al., 2002; Culham et al., 2003; Frey et al., 2005; Grol et al., 2007); SPLant, SPLpost, and IPS/TOS (Koyama et al., 2004); MIP (Rushworth et al., 2001; Grefkes et al., 2004); and pos IPS, vIPS, and aIPS from Corbetta and colleagues (Corbetta et al., 2000; Astafiev et al., 2003; Kincade et al., 2005).
