S_mean: brain regions where BOLD signal covaried positively with mean saliency. SA_dist: regions where BOLD signal covaried negatively with the distance between maximum salience and attended position. Sac_freq: regions where activity covaried positively with saccade frequency. p values are corrected for multiple comparisons at the whole-brain level (except for t values reported in italics), and k is the number of voxels in each cluster. Overt/Covert, spatial orienting with eye movements allowed/disallowed; FEF, frontal eye fields; a/pIPS, anterior/posterior intraparietal sulcus; SPG, superior parietal gyrus.
