Network analysis. The relationship between cue-related responses in the right IPS (X: initial variable) and target-related responses in the medial prefrontal cortex (Y: outcome variable) was mediated via the left fusiform gyrus (M: mediator/intervening variable). The X, Y, and M variables employed in the analysis involved contrast or interaction terms, as indicated in red font. The letters a, b, c, c’, refer to estimated path coefficients (see SI Text). FG, fusiform gyrus; IPS, intraparietal sulcus; MPFC, medial prefrontal cortex; Rewd, reward condition; No-Rewd, no-reward condition; I, incongruent trial; N, neutral trial. *P < .05, **P < .01, ***P < .005, two-tailed. The dotted line indicates a path that was not statistically significant after the mediator was taken into account.
