Behavioral-fMRI correlations and functional connectivity. (A) Behavioral sensitivity to saliency , i.e., the difference in luminance contrast sensitivity to detect the two different foregrounds, is correlated with fMRI saliency-sensitive response in the superficial layers of V1, giving a significant Pearson’s correlation coefficient <i>r</i>. Each circle represents one participant. (B) Pearson’s correlation coefficients <i>r</i> in the superficial layers of V1 and V2, and in the middle layer of IPS. The dashed line indicates the significance threshold after family-wise error (FWE) correction by a permutation test. (C) The feedforward and feedback pathways of saliency signals between V1 and IPS, assessed by the layer-specific generalized psychophysiological interaction (gPPI) analysis of functional connectivity. (D) Functional connectivity difference (90° vs. 15°) of the two pathways in C. Each gray dot represents a single participant. Error bars represent the standard errors of th
