Elevated FTP uptake in the anterior DAN is associated with impaired performance in the VOSP number location test. Coloured vertices on the cortical surface maps indicate the areas from which FTP signal (mean W-scores) was extracted for each patient and correlated with VOSP number location test performance. VOSP performance was not related to FTP signal within the visual network, but had a negative correlation within the DAN. When the DAN was split into its subnetworks, VOSP performance was found to be strongly negatively correlated with elevated FTP signal in the anterior DAN, but not the posterior DAN. VOSP performance showed the most robust negative correlation with the anterior-to-posterior DAN FTP signal ratio (the Tau Network Propagation Index).
