Evidence for segregated pathways linking caudal frontal cortex with SPL and IPS. A: 5 parietal seed regions were selected along the rostrocaudal extent of SPL and IPS. Two frontal seed regions, FEF and PrCv, were selected in dorsal and ventral precentral sulcus. All seed regions were selected using the discovery data set or meta-analysis of fMRI studies (Table 3). The coordinate locations are reported in Table 2. B: functional connectivity of FEF and PrCv with the 5 parietal seed regions, arranged in rostral (lateral) to caudal (medial) order, from the replication data set. Rostrolateral IPS seed regions (IPS1, IPS2, and IPS3m) are more strongly correlated with PrCv than FEF, whereas the mediocaudal SPL seed regions (SPL7A and SPL7P) are more strongly correlated with FEF than PrCv.
