Four V1 seed regions were selected using the calcarine fissure, histological V1 estimates (Amunts et al. 2000; Fischl et al. 2008) and the 17-network boundary estimate in the discovery data set. V1pd and V1pv were selected from the dorsal and ventral parts of peripheral V1, likely representing the ventral and dorsal peripheral visual fields, respectively. V1cd and V1cv were selected from the dorsal and ventral parts of central V1, likely representing the ventral and dorsal central visual fields, respectively. MT+d, MT+, and MT+v seed regions were selected from the dorsal, central, and ventral parts of the histological map of the MT+ complex so that MT+d and MT+v likely represent peripheral and central visual fields, respectively. Based on the overrepresentation of the lower visual field within macaque MT (Maunsell and Van Essen 1987), it is possible that the 3 MT+ seed regions might also represent the lower visual field. aMT+ was selected to be anterior and outside the MT+ histological map. V3A and V4 were selected based on their high correlation with MT+ in the discovery sample and were named using the approximate map of human visual areas (Van Essen 2004) as reference. Frontal eye field (FEF) and precentral ventral frontal cortex (PrCv) were selected from the caudal frontal cortex, whereas IPS2, IPS3m, SPL7A, SPL7P, and IPS1 were at or near the intraparietal sulcus (IPS). FEF, IPS2, SPL7A, and SPL7P were derived from the meta-analysis of functional magnetic resonance imaging (fMRI) studies (see Table 4). The PrCv region was selected based on its correlation with aMT+. IPS3m was chosen spatially between IPS2 and SPL7A. IPS1 was chosen on the lateral wall of rostral IPS. IPS2, IPS3m, SPL7A, SPL7P, and IPS1 were named using the probabilistic histological maps of the parietal cortex as reference (Choi et al. 2006; Scheperjans et al. 2008a; 2008b). Coordinates reflect the approximate center location based on the MNI atlas space.
